Smith Meter UPT Installation Service

Universal Pulse Transmitter (UPT)
Installation/Service

Bulletin MN01045 Issue/Rev. 0.7 (11/17)

General

The Smith Meter® Model UPT (Universal Pulse) Transmit­ter 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 cali­brator. If other mechanical stack accessories are required,
a calibrator adaptor kit is used for mounting the manual
calibrator above the UPT Transmitter.

Receipt of Equipment

When the equipment is received, the outside packing case
should be checked immediately for any shipping damage.
If the packing case has been damaged, the local carrier

should be notied at once regarding his liability. Carefully

remove the unit from its packing case and inspect for
damaged or missing parts.

If damage has occurred during shipment or parts are
missing, a written report should be submitted to the Inside

Sales Department, Measurement Solutions, PO Box 10428,
Erie, Pennsylvania 16514.

Prior to installation, the unit should be stored in its original
packing case and protected from adverse weather condi­tions 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 Trans­mitter. 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 tem­perature 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.

ATEX/IECEx Installation

Standards Used:

IEC 60079-0 6th Edition, EN 60079-0: 2012 +A11:2013,
UL 60079-0 6th Edition, CAN/CSA C22.2 No. 60079-0:11

IEC 60079-1 7th Edition, EN 60079-1: 2014. UL 60079-1
7th Edition, CAN/CSA C22.2 No. 60079-1:11

Cable entries must be in accordance to EN/IEC 60079-1

section 13.

For wiring systems utilizing cable glands the gland and or

thread adaptor must be Ex certied.

The cable end must be securely installed and depending
on the cable type be properly protected from mechanical
damage.

For wiring systems utilizing conduit, an Ex certied sealing

device must be used immediately at the entrance of the
enclosure. Any unused entry must be suitably blocked

with an Ex db IIB IP65 certied plug for ATEX and IECEx

applications.

Equipment bonding shall be provided at the external
grounding facility terminal, external connection is not

required when using metallic conduit or armored cable.

External grounding facility terminal wire range:
10-12 AWG (5.26 sq mm to 3.31 sq mm) wire.

CAUTION: To prevent ignition of hazardous atmospheres,
disconnect from supply circuit before opening. Keep tightly
closed when circuits are in operation.

WARNING: To prevent ignition of hazardous atmospheres,
do not open enclosure unless area is known to be non­hazardous. To reduce the risk of ignition of hazardous
atmospheres, conduit runs must have a sealing tting
connected within 18 inches of the enclosure.

Special Conditions For Safe Use:

- Special Fasteners: Cover Bolts - DIN 912 grade 12.9 (alloy
steel) M8 x 1.25, thread tolerance 6g, only replace with this

type.

- Select wiring and cable glands suitable for 80°C operation.

- Contact manufacturer at address listed for information on
the dimensions of the ameproof joints.
