Tuthill Corporations humble beginnings date back to 1892, when
James B. Tuthill purchased a clay quarry and a kiln and began
supplying Chicago common bricks to local construction rms. In the
early 1920’s, his efforts to improve lifting clay from the quarry turned
up a new transportation idea—a steam-powered truck engine.
The design eventually proved unworkable, but Tuthill recognized the
value of the engine’s small, internal gear pump, which injected fuel
oil directly into the truck boiler. The pump design was rened and
was marketed to companies that produced oil-red boilers for use in
residential and industrial heating, where it enjoyed great success and
formed the basis on which the Tuthill Pump Company was formed.
Over 120 years and ve generations later, Tuthill Corporation is a
global presence in vacuum pumps, blowers, plastics, and fuel and
chemical transfer systems. We take great pride in our “Made in USA”
moniker, making quality and durability top priorities. Tuthill Precision
Meters carry that legacy and competency in uid transfer products
to new levels. Our patented “Wave Form” gears provide extreme
accuracy through strict control of uid slippage in the metering
chamber, and our electronics work with virtually any metering or
management system.
Your choice of a Tuthill Precision Meter is an investment in
professional equipment that will pay dividends for years to come.
We appreciate your business, and look forward to serving you in the
future!

About Tuthill Meters
We thank you for purchasing aTuthill Meter for liquid
measurement service. Tuthill Meters,formerly Fluid
Power Products, is now atrade name of Tuthill Transfer
Systems. Fluid Power Products was established in
1980. Sinceits inception, the company has been
dedicated to manufacturing cost-effective, high
performance flow metering devices for petroleum,
industrial, commercial and municipal service.
Our facilities include computerized order entry and inventory
control, so that you are assured of accurate and prompt
de-liveries. Furthermore, our production personnel ensure
that each order, regardless of size, receives individual
attention.
Constant attention to new product development and produc-
tion design, our high standards of manufacture and final
testing are the reasons why Tuthill Meters meet your
most demanding requirements. With the ‘Waveform’
oval gear (2003 patent) meter accuracy is better than ever
before.
Our meters are used in batching, blending, process control
and to dispense fluids in liquid handling facilities throughout
the World. Service includes gasohol blends, bio-diesel, LPG
and special formulation racing fuels.
Principle of Operation
Positive Displacement meters have a measuring chamber,
where inlet & outlet are separated by rotors, a rotating
element or sliding vanes. As the liquid passes through the
flow meter, it causes the rotors/element/vanes to turn,
which forms the basis for volumetric measurement.
The Oval Gear metering principle is based on two elliptical
(oval) gears, which turn on center on two horizontal shafts
inside a measuring chamber formed by two overlapping
cylinders. The oval gears have meshing teeth along their
entire circumference, ensuring that
the gears will maintain correct position
in relation to each at all times,
without the use of timing gears.
The volume being transferred from the inlet to the outlet side
(= volume being measured) forms between the oval gear
and side of the measuring chamber, alternately in the upper
and lower half of the measuring chamber. In a full 360°
rotate, four such known volumes are released to the
downstream side of the flow meter.
.
With precision machining and close internal tolerances, the
slippage is minimal for superior linearity (accuracy) over a
broad turn-down ratio.
The TS Series meter is designed to provide:
F●● Assy: Electrical pulse signal to an electronic
register installed on the flow meter.
W●● Assy: Electrical pulse signal to a remote
electronicregister.
The flow meter is 100% gland-less with static O-ring seals
only. An internal magnet turns in the vertical plane; a sensor
mounted in flow meter end cover reads changes in the mag-
netic field, and generates 64 pulses per 360° rotation . Sev-
eral different signal types are available, to ensure signal
compatibility with all electronic registers.

other appropriate authorities.
In the event of a small, contained gas leak:
 Isolate and stop the leak
 Prevent accidental ignition
 Prevent entrance of gas into other portions of the
building. Be aware that LPG is heaver than air and
will seek lower levels
 Evacuate all people from the danger zone
 See that the gas is dispersed before resuming the
business and operations. If in doubt, notify your
local authorities.
IN THE EVENT OF A GAS FIRE
In the event of large fires or fires that are spreading:
Evacuate the building and notify your local fire department.
Stop the leakage only if you can safely reach the equipment.
In the event of small, contained fires that you can safely
control:
Stop the leakage if you can safely reach the equipment.
Then use the appropriate extinguisher: Class B fire extin-
guisher, water, fog, etc. depending on the equipment. If in
doubt, call your local fire department.
Safety Procedures
This manual provides warnings and procedures that are intended to inform the owner/operator of the
hazards present when using the Tuthill Meters and other products. The reading of these warnings
and the avoidance of such hazards is strictly in the hands of the owner/operator of the equipment. Neglect
of that responsibility is not within the control of the manufacturer of the flow meter.
The meters non-shock maximum operating pressure is
indicated on the meter name plate. The meter should
never be operated in excess of this pressure. Care should
be taken to eliminate thermal and hydraulic shock pres-
sures, so that they do not exceed the meters maximum
working pressure.

5
Installation & Operation
Installation (also see page 12):
 Positive Displacement meters are designed to operate full
of liquid. The meter should be installed in a manner, so
that it remains full of liquid at all times.
 Hydraulic shock can be harmful to flow meter and
other system components. Consideration to elimi-
nate hydraulic shock should be given in selection of
pump and design of the piping system.
 In critical installation, block valves and by-pass lines
are recommended. This allows the meter to be ser-
viced without interruption of flow in a critical process
application.
 Thermal and or over pressure relief valves are rec-
ommended and should be installed whenever it is
possible to block (isolate) the meter between two
valves. Thermal pressures many times the operating
pressure are possible with only a small rise in tem-
perature.
 Protective caps installed in flow meter flanges prior to
shipment should remain in place until you are ready to
install in the piping system.
 Keep all external surfaces of the meter clean.
 It is recommended that a Strainer be installed upstream
of each flowmeter, to prevent damage from foreign mat-
ter, such as welding slag, pipe scale or parts breaking off
other equipment. When using Tuthill right-angle strainer:
 Inlet can be either from the front or the rear of the
strainer (inlet flange & strainer basket cover have same
bolt pattern, and can be reversed in the field).
 Allow adequate space for removal of strainer basket
cover, so strainer basket can be cleaned.
 Strainer basket comes standard with 200 mesh for
LPG (Propane) service.
 Flush the system with a liquid compatible with the flow
meter to remove all debris, scale and welding slag prior
to flow meter installation.
If this is not possible, temporarily remove rotors (oval
gears), and reinstall after the system has been flushed.
 Apply pipe compound to male threads, to install the two
companion flanges. Tighten to a position, that allows
the meter to bolt to the companion flanges, free of pipe
stress.
 The meter should always be supported by bolting
firmly to a solid platform or foundation. Never use the
connecting pipe as the means of support.
 When installing the flow meter, consider future mainte-
nance of both flow meter and accessories. The meter
can be serviced in place, provided block (isolation) valves
are included, and adequate space allowed.
OPERATING TEMPERATURE
TS Series W●● & F●● assemblies are rated for opera-
tion from -40°F/+257°F (-40°C/+125°C), subject to possi-
bly tighter ratings applicable to the electronic register.
OPERATING PRESSURE
Maximum non-shock Operating Pressure is:
350 PSI (24 BAR) at 100°F (= 38°C)
The flow meter should never be operated in excess of this
pressure. Care should be taken to eliminate thermal and
hydraulic shock conditions, so that system pressure never
exceeds Maximum Working Pressure rating.
SAFETY INSTRUCTIONS
Make sure that all necessary safety precautions have been
taken, including proper clothing, personal safety equipment
and fire safety equipment if required.
Before Start-Up of the Flow Meter, make certain that:
1. The meter is properly mounted, secured and piped.
2. All connections are tight.
3. All bleed and drain valves are closed.
4. Do NOT smoke near meter, or use meter near an open
flame, when metering flammable liquids. Fire or Explo-
sion could result.
Install the Flow Meter and Accessories in compliance
with all applicable Local, State & Federal Construction,
Electrical and Safety Codes. Additionally LPG meters
must be installed in accordance with the requirements
of ANSI-NFPA 58.

Follow the manufacturer’s recommendation fully when in-
stalling pumps. Give particular attention to factors like: use
of foot valves, pipe size to the inlet and conformance to net
positive suction head (NPSH) conditions when suction
pumping is required. Following the manufactures’ recom-
mendations will minimize air and vapor elimination prob-
lems.
Start-Up:
Fill the system slowly to avoid operation on air or vapor.
This can be accomplished in the following manner:
Throttle the meter inlet valve, and allow the meter and pip-
ing to fill slowly by gravity.
Crack open the outlet valve and start the pump, then slowly
open the inlet valve until the system is up to pressure. Open
the outlet valve fully to establish full flow. Check the flow
rate to assure the meter is operating within specified rates.
The meter is not designed to operate on air, but the design
and materials of construction of the Tuthill Meter allows for
operation on vapor for short periods of time without damage
to the elliptical gears or other meter internals.
Note: Overspeeding andhammer caused bythe
presence of vapor in the system can cause
internal damage to the meter.
6
Installation, Start-Up & Operation
 The Vapor Eliminator is included in the flow meter as-
sembly, with one vent port connected to differential valve
(or 3-way solenoid valve, when included). The other vent
port must be piped back to storage.
 Connections for calibration should be provided during
installation. An easy means for diverting flow into a cali-
bration vessel (or master meter) should be considered.
Refer to Tuthill Technical Manual for a diagram of the
sug-gested installation.
Operation Requirements:
Upstream lines must be maintained full to prevent air/vapors
from entering the meter. If the upstream or inlet lines are
constructed in a manner which allows reverse flow, foot or
back check valves should be installed.
Underground tanks that are furnished with a submersible
pump will eliminate many problems that occur with positive
displacement pumps with suction pipes, when the suction
piping is incorrectly sized creating too large a lift.
Every meter should be calibrated under actual service and
installation conditions. Follow your local Weights and Meas-
ures recommendations.
Give careful attention to your system’s pumping equipment
and piping, because of their influence on the liquid being
measured as it enters the meter assembly. Systems should
be designed free of conditions that cause or introduce en-
trained air or vapor.

Vent Line:
The vent line from the meter’s vapor vent to the vapor space
on the supply tank should a minimum of 1/4” inside diameter
tube or pipe. A shutoff valve must be installed in the vapor
vent line to allow removal of the strainer or service on the
meter. The vapor release vent line must be returned to the
vapor space of the supply tank and normally should not be
made common with the other vapor return lines or pump by-
pass lines. When properly installed, this line must permit
free flow in either direction. If the vent line is closed the me-
ter will not function, as the differential valve will not open.
These instructions must be followed to maintain proper func-
tion of the differential valve.
Support:
Prevent pipe strain or stress from occurring when making
connections to meter or accessories and during repairs.
Pipe strain and stress occurs when the pipes are not sup-
ported or are not aligned correctly to the meter. The weight
of the pipes must always be supported independent of the
meter. This meter and accessories can easily be removed
without affecting the pipes or the pipe alignment. Never
leave any of the pipes hinging.
12
Calibration
Theory of Operation;
The Tuthill Meter LPG metering system combines an
oval gear positive displacement meter, differential valve,
strainer and vapor eliminator in one assembly. The
differential valve incorporates a piston type construction
with the piston mov-ing away from its seat when at least 15
PSI pressure (above product vapor pressure) is
maintained at the meter outlet. The soft seat valve
assures measurement accuracy by re-quiring pump
operation for delivery, by requiring adequate back
pressure to prevent product vaporization during meas-
urement and by requiring blockage of flow when the vapor
eliminator release valve is open. The strainer prevents for-
eign particulate from entering and damaging the meter. The
meters close tolerance machine construction and no metal
to metal contact provides accurate liquid measurement.
Installation on a Truck:
Flow Meter:
Install the meter assembly in a dispenser cabinet, or a truck
deck to a secure base using the bolt holes on the “feet” of
the strainer assembly base. Make inlet and outlet connec-
tions at the flanged surfaces on the strainer and differential
valve, respectively. Leave a minimum of 12 inches be-
tween he strainer flange and any obstacle for servicing
the strainer.
Flow meter can be TS06A
(as shown in diagram), or
model TS10A = straight-
through, where the back-
check/differential valve is
mounted with outlet facing
down.

and scratches.
 Repair pulled threads with threaded insert fasteners.
These can be used in many instances. Contact your full-
service distributor for advice if this occurs.
 Coating threads: When removing and replacing bolts and
screws in a meter, always coat the threads with anti-
seize.
 Removing flange seals: When removing the flange as-
sembly, always carefully remove the O-ring seal. Make
sure that the flange surface is clean. Discard and replace
the old O-ring seals if it is nicked or scratched in any way.
It is undamaged, it can be re-used.
 Examine all fasteners: make sure fasteners are not bent,
rusted, or have pulled or burred threads. The threads
should all appear evenly placed. If the bolts are bent,
check the housing and cover for flatness. Use a straight
edge to determine flatness. Use a stone to remove any
burrs on the flat surfaces for the housing.
 Look for gaps: When disassembling a meter, use a feeler
gauge to check for gaps between the post and gear
plates and housing. If you do find gaps, check the plates
for flatness with a straight edge. Gaps can be caused by
shock problems that must be resolved. Contact your full
service distributor, or the Service Department at
Tuthill Meters for assistance if this occurs.
 Check the O-Rings: O-rings should be smooth. Cracked
or worn O-rings should be replaced. However, a more
serious problem of shock my have occurred if the O-rings
are nibbled or extruded. Shock problems must be verified
and resolved. Contact your full service distributor, or the
Service Department at Tuthill Meters for assistance if
this occurs.
 Check the post and gear plates: Check the plates for
flatness. Use a straight edge. Warped plates can be
caused byhydraulic shock problems that must be re-
solved. Contact your full service distributor, or the Ser-
vice Department at Tuthill Meters for assistance if this
oc-curs.
 Weights & Measures: Check with the regulatory agency
that governs Weights and Measures in your area. Re-
moving a seal wire may require Weight & Measures re-
calibration.
13
Meter Maintenance
Storage:
If the meter is used for seasonal work, at the end of each
season the meter should be removed from the system and
thoroughly flushed with a compatible liquid. This includes
removing the drain on the front and rear covers. Then flush
the product from the front and rear covers. If flushing with
water is preferred, extra care should be taken to drain the
meter completely and to dry all internal parts. Immediate
refilling with a compatible liquid (or oil misting) is essential to
prevent corrosion as well as ice damage to parts from mois-
ture that was overlooked after flushing and drying.
Preparing for Service:
 Close the belly valve of the supply tank.
 Close the valve on the vapor return line.
 Close the manual valve in the supply line on the inlet side
of the meter. If no manual valve exists on the inlet side,
consult the bobtail manufacturer or service provider/
installer for procedures to depressurize the system.
 Slowly open the valve/nozzle on the end of the supply line
 After product is bled off, close the valve/nozzle at the end
of the supply line.
 Open the bleed valve provided by your installer to relieve
the system pressure. Product will drain from the meter
system.
 As product is bleeding from the bleed valve, slowly re-
open and close the valve/nozzle on the discharge line.
Repeat this step until the product stops draining from the
bleed valve and discharge line valve/nozzle.
 Leave the discharge line valve/nozzle open while working
on the system.
General Service:
 Do not scratch or mar any of the precision machined sur-
faces by prying or sanding parts.
 Torque specifications. All fasteners such as screws and
bolts should be torqued to proper specifications. See the
“Torque Chart” in this manual.
 Stone the machined surfaces when reassembling the
meter to assure the machined surfaces are free of burrs
Relieve all internal pressure before servicing. Line pressure must be 0.0 PSI
Serious injury or death from fire or explosion could result from maintenance
of an improperly de-pressurized and evacuated system.
Danger!! Danger!! Danger!!

 Remove the eight screws (#19) from flow meter front
cover (#5). Detach the front cover from meter body (#1).
 Remove the four screws (#20) from the gear plate assem-
bly (#4). Detach the gear plate assembly.
 Inspect the gear plate (#4) for wear. Make sure that it is
not scratched, or bent. If the gear plate is not damaged, it
may be reused.
 Inspect the target magnet assembly (#29A) for damage
or bearing wear. Significant movement between the tar-
get magnet shaft (#29C) and the bearings (#29B) indi-
cate the need to replace the bearings.
 Replace the bearings (#29B) if necessary. It is recom-
mended that the target magnet. bearings & drive shaft
assembly be replaced at the same time.
 Remove and inspect the oval gears (#2). If the gears are
not damaged or worn, they may be re-installed. They
must be installed at 90º to each other to function properly.

Meter Maintenance
Meter Disassembly:
The great advantage of Tuthill Meters model TS10AF83
& TS10AF93, is that the flow meter can be serviced in
place, without removal of the electronic register, or
cable con-nections to printer/remote controller.
Be sure to replace all seals when servicingthe meter
 Remove the security seal wire from the four pulser hous-
ing screws (#30).
 Remove the two screws (#18) from the collar (#8) on the
register adaptor support. Detach the collar (#8).
 Remove the four screws (#30) from pulser housing cover.
Detach the cover (#12).
 Disconnect pulser output cable from the terminal board
(#13) or SCL (#13). You may replace the terminal board/
SCL at this time, if necessary. When replacing the SCL,
please reference flow meter Serial No. when ordering the
replacement. To replace the pulser (#10), remove three
screws (#31) from the retaining plate (#11).
Relieve all internal pressure before servicing. Line pressure must be 0.0 PSI

it is recommended that the flow meter be replaced.
 Reinstall the meter gear plate (#4).
 Reinstall the cover (#5).
 It is recommended that all O-rings and seals be replaced
during service. If seals are reused, a good inspection is
critical.
 Reinstall the pulser (#10) and terminal board/SCL (#13) if
necessary. Reconnect pulser output cable.
 Reinstall the pulser housing cover plate (#12) on front
cover (#5). Replace the pulser cover “O” ring if neces-
sary. A small amount of petroleum jelly may be used to
help hold the “O” ring (#15) in place while re-installing.
 Fill the flow meter with gas, and inspect for leaks
15
Meter Maintenance
 Inspect the post plate and posts. Replace if there is any
wear or scratches on the post plate. A small amount of
polishing (surface marking) on the post plate (#3) is nor-
mal. If the polishing results in an indentation or grooves
in the surface, replace the post plate assembly.
 Inspect the meter body for damage. Use 200 grit paper
to remove small scratches and blemishes, if the damage
is more than superficial, replace the body.
Clean all surfaces using a brush or fine (200 grit) emery
cloth to remove small scratches or deposits. IF THERE
ARE LARGE SCRATCHES OR DAMAGE THAT CAN
CREATE A LEAK PATH, REPLACE THE PART.
 Rotate the oval gears (#2) on the posts and insure that
there are no rubs between the gears and the body (#1).
A Rub would indicate a bent post or a bent post plate
assembly (#3). If this occurs, replace the post plate as-
sembly (#3).
 The expectations would be, that the post plate assembly
(#3) should be replaced with each second or third set of
gears depending on service conditions (flow rate & total
volume).
 Install a new oval gear set (#2) if necessary. Gears
should be perpendicular to each other. The gears will not
rotate a complete revolution if not installed properly.
Once installed, the gears should rotate freely, without
binds or rubs.
Check clearances between the gears and the body (#1).
There should be a minimum of .003 inch (0.076 mm)
between gears (#2) and the gear plate (#4). If there is
any binds or rubs between the gears and the meter body,

Strainer
The same strainer is used with both TS06A (single or dual)
& TS10A models; in single configuration, one side of the
strainer is closed with a blind cover (#33). In dual configura-
tion, a check valve is installed between the strainer and
each flow meter.
When temperature compensation is required, a thermo well
is available for installation in strainer body (#8). When tem-
perature compensation is not required, the strainer is sup-
plied with a plug instead.
 Remove the four bolts (#15) from the strainer basket
cover and remove the cover (#7).
 Inspect the seal (#12) and replace if damaged or brittle
 Remove the strainer basket (#10). Clean the basket with
low pressure air, blowing out all loose sediment. Wash
the basket with solvent.
 Inspect the basket for holes or other damage and replace
if necessary.
 Re-assemble in reverse order, making sure that all bolts
are torqued to the proper specifications.

Strainer & Vapor Eliminator
Vapor Eliminator
 Disconnect the vapor return line flange (#2) and the differ-
ential valve tubing (not shown).
 Remove five bolts (#3) from the vapor eliminator housing.
 Remove the cover (#4) from the vapor eliminator housing.
 Remove the float and slide valve assembly (#34) from the
cover for inspection.
 Inspect the float for damage or leak-
age. A crack will allow the float to fill
with liquid and sink, thus preventing
the valve from closing. A collapsed
float is an indication of overpressure
or hammer (shock) conditions. These
operational conditions must be cor-
rected before reusing the flow meter.
 Inspect the slide valve (34.1 & 34.2).
Remove any build-up of salts or dirt,
which may cause the valve to stick.
The valve should slide freely, without
any signs of sticking. There should be
no scratches or burrs on the valve
assembly. Replace if there are signs of damage.
 Inspect all seals, and replace if damaged or brittle.
 Re-assemble the vapor eliminator in reverse order, mak-
ing sure that all bolts are torqued to the proper specifica-
tions.

Inlet Check Valve (optional component)
 Disconnect the outlet piping from the meter assembly at
the differential valve outlet flange.
 Remove the meter as detailed in the METER DISASSEM-
BLY section.
 Remove the back check valve assembly (#11a), which
sits between the strainer and the adaptor on flow meter
inlet.
 Manually open and close the valve to assure proper op-
erations.
 Inspect for dirt of salt build-up and clean if necessary.
 Inspect the seals for wear or damage. Replace worn or
brittle seals.
 Reassemble the valve and install in the strainer housing.
This valve is optional and will not retrofit into strainer
housing not originally supplied with the valve.
 Reassemble the system making sure bolts are torqued to
the proper specifications

Differential Valve
Differential Valve
 Remove the companion flange from valve outlet.
 Detach the tube from the vapor eliminator from the differ-
ential valve cover (#2).
 Remove the Screws (#1) securing the cover (2) from the
valve body (#4).
 Remove the differential valve piston assembly (#7) and
spring (#6).
 Inspect the valve body (#4) and cover (#2) for damage.
Clean all surfaces of dirt or deposits using a fine (200 grit)
emery cloth if necessary. If damage is more than superfi-
cial, replace the valve.
 Inspect all seals and replace any brittle or damaged
seals. It is recommended that all seals be replaced dur-
ing service.
 Replace the U-Cup seals (#7a). Note proper position of
the seals. Use a small amount of Teflon lubricant to help
install the seals.
 Replace the square cut seal (#7b). Use thread sealer
(Locktite Blue) when installing the fastener (#7e).
 Re-assemble the valve in reverse order, making sure that
bolts are torqued to the proper specifications..

Trouble Shooting
Problem
Leakage from seal cover.
Product flows through meter but the
register does not operate
Breaking teeth on gears.
No flow or low flow through the meter
Meter operates too slowly:
Product flows through the meter but
register does not record properly:
Probable Cause and Solution
 Seal has been damaged due to shock
 Cover bolts have not bee tightened sufficiently
 Replace seal and /or re-torque bolts
 Pulser is not functioning properly
 Meter gears are jammed and not turning
 Replace the pulser, inspect internal meter parts
 Starting or stopping flow too rapidly.
 Normal wear after long service
 Replace gears
 Correct system operation
 Check pump by-pass setting.
 Faulty non-functioning pump
 Differential vale not open or not functioning. Replace valve
 Meter “frozen” due to build up of salts or frozen material. Clean meter
internals and inspect for damage
 Vapor vent line valve shut or obstruction in vapor vent line. Open valve or
remove obstruction
 Strainer dirty and plugged. Clean Strainer
 U-Cups on differential valve leaking. Replace U-Cups
 Differential valve internal mechanism faulty. Valve does not open fully.
 Meter gears or rotors partially “salted”, enough to slow the rotating gears.
To correct, clean gears.
 Strainer partially plugged. Clean strainer basket.
 Pump not functioning properly. Repair pump
 Pulse output board faulty, or not calibrated for electronic register.
 Vapor release valve sticking.
 Differential valve leaking.
 Repair or replace as necessary.
