Smith Meter UPT Manual

General
The Smith Meter®Model UPT (Universal Pulse) Transmit-
ter is a photo-electric, dual channel, high resolution, pulse
generator that is directly connected to the output shaft of a
positive displacement meter.
The UPT Transmitter is installed at the lowest level in the
meter accessory stack. It is designed to be mounted directly
on the meter dome adaptor and replaces the manual cali-
brator. If other mechanical stack accessories are required,
a calibrator adaptor kit is used for mounting the manual
calibrator above the UPT Transmitter.

tions and abuse.
Mechanical Installation
When ordered with a Smith Meter®positive displacement
(PD) meter, the Model UPT Transmitter will normally be
factory installed directly on the meter. The following steps
are required for eld mounting the UPT Transmitter to a
Smith Meter PD meter:
1. Remove all accessories (counters, mechanical temperature
compensators, transmitters, etc.) from the meter.
2. Remove the existing calibrator, located inside the meter
dome adaptor.
a. Remove the cap protecting the external calibrator
adjusting stem by removing the two mounting screws.
b. Indicate the calibrator setting with a line that intersects the
calibrator dial and its adjacent part.
c. Remove the calibrator adjusting assembly by removing
the two mounting screws and carefully withdraw the stem
assembly from the housing without changing the adjusting
screw.
d. Remove the calibrator from the meter dome adaptor by
removing the two small hold-down screws and carefully
rotating the calibrator body clockwise.
e. Attach the blind plate (provided in the adaptation
kit) over the calibrator stem assembly hole.

3. Mount the UPT Transmitter onto the meter dome
adaptor. A weatherproof gasket and three 3/8" - 16 x
1-1/4" mounting bolts are provided. Care must be taken
to properly engage the transmitter coupling or gear to the
meter drive coupling or gear.
For adaptation to old style (single case) PD meter (old
style PD meters include Models AB, AS, B, or S-12, 13,
24, 28, 30, 35, 42, 45, 50, 60, 65, 75, and 100), also
mount the 5/8" spacer between the UPT Transmitter and
meter dome adaptor. An additional weatherproof gasket
and longer mounting bolts are provided.
4. If a live calibrator is required to be installed below the
UPT Transmitter then a UPT calibrator adapter kit is
required P/N 529288011. If a live calibrator is required on
top of the UPT Transmitter then a remote calibrator kit is
required P/N 529288001.
5. If additional stack accessories are not required, install a
blind cover plate (10078-1) on the top of the UPT Trans-
mitter. The manual calibrator and other parts removed in
previous steps can be discarded (see note below).
6. If additional stack accessories are required, reinstall
the previously removed calibrator and stem assembly
into the new calibrator adaptor housing located on top
of the transmitter by reversing the removal procedure
described in Step 2 above (see note below).
7. Install oiler in calibrator housing (parts provided in the
adaptation kit):
a. Attach tube to oiler.
b. Insert tube through calibrator housing.
c. Drive oiler (force t) into housing.
d. Attach oiler tube to top of calibrator, just below drive
coupling.
8. Reassemble the accessories (counter, mechanical tem-
perature compensator, etc.) onto the calibrator housing.
9. Check the calibrator setting and adjust (if necessary) to
the setting recorded in Step 2b. Recalibration of the me-
ter may be required due to breaking of seals on original
calibrator adjustment and is recommended to maintain
optimum meter accuracy.
For adaptation to old style PD meters, the meter must be
recalibrated because the new factory-installed calibrator
is not adjusted.
10.If desired, a seal wire can be installed (like a belt) around
the middle of the UPT Transmitter cover and housing to
prevent unauthorized tampering with internals.
Note: With the calibrator removed from the meter, the oiler
tting on the PD meter is no longer needed and should be
sealed off.

Step 12. Attach the coupling on the end of the shaft
and insert hairspring cotter pin.
Step 12
Step 13. Inspect cover and housing at machined
surfaces (ame paths) for any signs of
damage. If surfaces are damaged the unit
must be replaced as this is part of the (ame
proof/explosion proof) protection. Apply a
light coating of multi-purpose synthetic
grease to the cover o-ring and ame path
joint before reattaching the cover to the
housing. This helps maintain a water-tight
seal and provides additional corrosion
protection to the ame path. TechnipFMC
synthetic grease P/N 644886401 is
recommended. Apply a nickel based
anti-size lubricant to all cover fasteners.
TechnipFMC P/N 646002401 is recommended.
Step 13
Step 14. Close the cover and tighten the eight cap
screws around the perimeter of the cover
using the sequence shown. The nal torque
should be 15 LB-FT / 180 LB-IN (20.3 Nm /
207.4 Kg. cm).
Step 14
Step 15. After tightening all cover bolts, check the
joint with a 0.0015" (0.038 mm) feeler
gauge all the way around the outer
perimeter of the enclosure. The feeler
gauge should not insert more than 0.125"
(3.2 mm) at any point. If it does, remove
the cover and recheck the cover joint for
any foreign objects, reassemble and check
again.
Step 15

Storage Instruction
The presence of moister / water causes excessive corrosion, damage to the electronics and eventually the units to fail.
To prevent moisture / water ingress during storage observe the following guidelines:
• Keep units in a dry, protected place
• Avoid storing units outside (if outside is only choice, protect from elements)
• Make sure the conduit port on the back side of the housing is closed with the factory provided 3/4" NPT plug
• Use the factory provided Vapor Desiccant Pack (secured with double-sided adhesive tape) inside the housing
• Keep the covers mounted to the housing to protect the electronics
Note: If units are installed and are awaiting start-up / commissioning observe the following guidelines:
• Use conduit seal-off tting as per applicable electrical code
• Do Not leave units installed with open seal-off tting and / or removed covers where moisture can enter into
the UPT housing
