Section1—Introduction
Barton 7000 Series Flowmeters
Barton 7000 Series owmeters are specially designed to accommodate a
broad range of precise uid measurement applications. They can accept larger
ow rates with lower pressure drops than other meters in their class, and fea-
ture a self-ushing design for longer sustained accuracy. Their high-frequency
digital output is ideal for interfacing with digital readout equipment. The 7000
Series' symmetrical bi-directional design supports reverse ow applications,
without reducing accuracy or ow capacity.
All meters are shipped with a pickup coil. Each meter assembly includes two
locknuts, two ow straightener tube assemblies, a center shaft, two diffus-
ers, and a rotor, and is factory-calibrated with water. Bearing type varies with
models: Models 7100 and 7300 feature wear-resistant tungsten carbide sleeve
bearings and thrust washers. Models 7200 and 7400 feature self-lubricating,
precision stainless steel ball bearings. The Model 7400 features bearings with
dry lubricant impregnated ball separators.
During operation, uid passes over the diffuser section and is accelerated onto
a multi-blade hydro-dynamically balanced turbine rotor. The rotor speed is
proportional to the volumetric ow rate. As the rotor turns, a reluctance type
pickup coil (mounted on the meter) senses the passage of each blade tip and
generates a sine wave output with a frequency that is directly proportional to
the ow rate.
The rotor is the only moving part of the Barton turbine owmeter. The small
lightweight rotor hubs ensure fast response to process ow changes. The rotor
is hydro-dynamically balanced during operation, eliminating the need for me-
chanical thrust leveling. This low-friction design improves metering linearity
and reduces wear and maintenance.
The pickup coil is inserted into a conduit adapter that is welded to the outside
of the turbine body. The boss is explosion-proof/ameproof with 3/4" male
NPT electrical threads. The pickup coil can be removed for troubleshooting
without depressurizing the meter or stopping uid ow.

MeterPickupCoil(s)
A variable reluctance generating pickup coil contains a permanent magnet and
a wire winding. In Model 7100, 7200 and 7400 owmeters, the rotor blade of
the turbine meter is made of a ferritic stainless steel such as grade 430. The
movement of the rotor blade in proximity to the magnetic eld of the coil tip
produces an AC type voltage pulse within the coil winding. In Model 7300,
the ferritic bars imbedded in the rotor shroud interact with the pickup coil.
Because the bars on the shroud outnumber the blades on a standard rotor, the
7300 owmeter provides more pulses per unit volume (resolution). This fea-
ture is valuable when proving large-capacity meters with a small-volume prover.

5
Model 7000 Series Turbine Flowmeter Section 1
Shielded wire cable conveys the output of the pickup coil to compatible elec-
tronic instruments to indicate ow rate, record, and/or totalize the volumet-
ric ow. Since the coil itself does not require electrical power, the standard
pickup coil incorporates connection pins that mate to a quick connector.
The pickup coil can drive a variety of instruments including ow rate indica-
tors, totalizers, preampliers or ow computers/RTUs. Preampliers are used
to transmit the coil signal over extended distances to remote-mounted instru-
ments.
The meter may be factory-tted with multiple coils for redundancy, indication
of ow direction or pulse train verication.
The pickup coil type and magnetic strength vary with application require-
ments. For coil replacement, refer to the part number etched on the coil body.

Section2—InstallationandOperation
Unpacking
All Barton owmeters are tested and inspected during manufacture. However,
the instrument should be inspected at time of unpacking to detect any damage
that may have occurred during shipment.
Unpacking Procedure
1. For applications requiring special cleaning/precautions, a polyethylene
bag is used to protect the instrument from contamination. This bag
should be removed only in an extremely clean environment.
2. Unpack the meter and verify the accuracy of the information listed on the
packing slip (proper model number, serial number, calibration data, etc.).
3. Remove the threaded protectors or ange covers from the meter housing.
4. For meters up to 3-inch size, place the meter in a horizontal position
and blow (lung pressure should be sufcient) into the inlet port. Place
larger meters in a horizontal position and turn the rotor by hand or with
a wooden dowel. In either instance, the rotor should turn freely with no
evidence of roughness or binding in the rotation.
5. Visually inspect the meter inside and outside (without disassembling the
meter). Report any visible damage to Cameron immediately.
6. Replace the thread protectors and ange covers, then place the meter
back inside the polyethylene bag. Note: Meters may be stored indenitely
in the polyethylene bag.

Model 7000 Series Turbine Flowmeter Section 2
BestPracticesforInstallation
Before installing a Barton turbine owmeter, read the following best practices
in their entirety.
Filtration
All meters should be installed with upstream ltration to isolate the meter
from damage from foreign objects in the piping system. See the Barton 7000
Series product data sheet for recommended ltration size. Cameron offers
start-up screens as an optional accessory to prevent damage from foreign
objects.
Avoid the use of Teon® tape on body threads. Strands can enter the ow-
stream and collect on the rotor, causing measurement error.
All meters should be isolated from gas or liquid “slugs” which can cause
damage by over-speed and water hammer.
Electrical Installation
Consider the process operating temperature when selecting the type and
location of electric tting and instrument components. Heat conducted and
radiated from the turbine can damage wiring, connectors, electrical housing
and circuit boards. The meter can be installed so that the pickup coil is in any
plane. Avoid orienting the pickup coil in a 12 o'clock position in applications
with elevated temperatures.
Where possible, minimize the length of signal transmission cables from the
pickup. The signal from the turbine is a low-voltage AC sine wave that can be
as low as 30mV peak-to-peak. Electrical noise on the wires will cause false
counts on the readout instruments. Direct-mounting a totalizer or preampli-
er is preferred. If this is not possible, ensure that the signal cable is not near
power cables, other signal cables, or routed where electrical noise may inter-
fere with signal transmission.
Follow common wiring installation practices, using quality cable (twisted
pair, shielded with ground wire).
Flowmeter Position
Barton turbine owmeters are calibrated in a horizontal position. Therefore,
the best correlation of calibration occurs when the meter is operated in this
plane. However, the meter will operate satisfactorily in any position.

10
Section 2 Model 7000 Series Turbine Flowmeter
Flowmeter Location
See Figure 2.1 for reference. Location of the owmeter to obtain optimum
accuracy is dependent upon several factors.
• Relative to the System—When the ow is expected to be intermittent, the
meter should not be mounted at a low point in the piping system since
solids can settle on, or congeal around the rotor. These solids can cause
the rotor to freeze or otherwise be damaged.
• Tolerance to Mechanical Vibration—The turbine meter is constructed
to withstand rugged service. However, meter life can be increased by
locating the meter so as to protect it from the direct shock or mechanical
vibration.
• Tolerance to Electrical Interference—To obtain the best electrical signal
output from the meter, locate the meter at a distance from sources of elec-
trical interference. A preamplier is recommended for use on all installa-
tions to reduce the effect of undesired noise.
• Where practical, install the meter upstream of control valves and pres-
sure regulators. Where necessary, the meter should be at least 100 pipe
diameters from the valves.
Model 7400 owmeters feature a pressure tap on the body opposite the rotor.
For compliance with international measurement standards, any pressure sen-
sor used for computation of corrected volume should sense pressure from this
tap.

gardless of the material that the tting passes through.

13
Model 7000 Series Turbine Flowmeter Section 2
System Pressure
The maximum and minimum system pressures must be considered when
installing the turbine meter into the system.
• Minimum Meter Pressure—To obtain proper response, a back pressure
should be applied to the meter. This back pressure should be at least
twice the pressure drop of the meter at maximum ow (all meters). For
liquid meters, the back pressure should be twice the pressure drop of the
meter at maximum ow, plus twice the uid vapor pressure.
Minimum Pressure at the Meter = (2 x Net Pressure Drop at Maximum
Flow) + (2x Vapor Pressure of Fluid)
Some piping arrangements cause this amount of back pressure on the me-
ter due to downstream restriction, valves, etc. If additional back pressure
is needed, a downstream orice or valve can be added in accordance with
the piping arrangements shown in Figure 2.1, page 11.
InstallationProcedure
Prior to installing the turbine meter into the system, perform the following:
1. Install a “spool piece” and allow sufcient ow through the system to
completely ush any foreign material from the system. If foreign mate-
rial is expected in the ow the uid should be ltered. This is especially
important for ball bearing meters.
2. Remove gas "slugs" from liquid meter ow lines and liquid "slugs" from
gas meter ow lines.
3. If the meter is used in a cryogenic application, (available by special order
only; limited to model 7200 meters), install a bypass for cooling the pip-
ing without passing uid through the meter (Figure 2.2). This prevents
gasication of the cryogenic uid and ensures all ow passing through
the meter is liquid.
Figure 2.2—Flowmeter bypass
4. If liquid meters are to be "proved" for accuracy in-situ using a portable
prover, install prover taps per API standards.
5. Install a straight section of pipe on either side of the meter. This pipe
must be the same nominal pipe size as the meter with a length of at least
10 pipe diameters upstream and 5 pipe diameters downstream. (For
example, a owmeter with a 2-in. nominal diameter requires a 2-in. pipe.

14
Section 2 Model 7000 Series Turbine Flowmeter
The section of straight pipe upstream must be 20 in.; the section down-
stream must be 10 in.) Do not install throttling valves within 100 pipe
diameters upstream of the owmeter.
6. Install a ow straightener upstream and downstream of the meter. The
applicable lter should be selected according to ISA Standard RP31.1.
All uids to be used with a Model 7200 turbine meter should be free of
particles larger than approximately 10 microns.
7. Align the meter bore with the pipe, ensuring that the direction of ow
corresponds with the direction of the arrow engraved on the meter body.
All Barton turbine owmeters have “IN” and “OUT” stamped into the
housings to identify the direction of ow in which the meter was cali-
brated.
8. Insert bolts and apply torque for a leak-proof seal. See Tables 2.1 and 2.2,
page 11, for bolt size and torque requirements.
9. Install the magnetic pickup as follows.
a. If the meter will be used in a Class I, Div. 1 area, apply an industrial
thread-locking compound to the threads of the magnetic pickup. This
step is not required for non-hazardous installations.
b. Screw the magnetic pickup clockwise into the conduit adapter until
nger-tight. Do not tighten with pliers.
c. Attach the signal cable connector to the pickup and turn the swivel
nut until the connection is snug. Do not over-tighten.

Section3—Maintenance
Barton 7000 Series owmeters have a proven history of providing long cycle
periods between maintenance intervals. It is recommended the meters be
inspected every 3 to 5 years unless measurement anomalies occur. Many
installations are suitable for much longer maintenance cycles.
RoutineMaintenanceChecklist
Perform the following steps as part of your routine maintenance.
1. Before removing internal components from the meter, check the rotor to
determine if it turns freely.
2. Disassemble the meter and check for evidence of erosion or other me-
chanical damage to the interior of the meter body or internal components.
a. The rotor blade edges should be dened and not excessively round-
ed.
b. The rotor should be uniform and symmetrical.
c. Models 7100 and 7300 tungsten carbide bushings and bearings
should be free of radial play.
d. Model 7400 tungsten carbide bushings and bearings are dry lubricat-
ed and may emit a uniform sound and may not feel perfectly smooth
when rotated. This is normal.
e. Model 7400 and Model 7200 bearings should be free of axial and
radial play.
3. In a vented area, clean each part thoroughly in di-chlorethylene or any
similar cleaning solvent before reassembling the meter.

RepairKits
Should an internal component of a Barton turbine owmeter require replace-
ment, replace all internals with a repair kit. See Tables 3.2 through 3.4, page
19, and Table 3.5, page 20, for a complete list of repair kits.
Repair kits are factory-calibrated with water using eight data points and two
repeat points. They are calibrated with the meter in which they are to be in-
stalled. Therefore, they should be purchased with the meter to prevent down-
time. If the repair kit has not been calibrated and on-site proving (calibration)
cannot be performed, return the meter and the repair kit to the factory for
calibration.
