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.

Mechanical Installation
When ordered with a Smith Meter
(PD) meter, the Model UPT Transmitter will normally be
factory installed directly on the meter. The following steps
are required for field mounting the UPT Transmitter to a
Smith Meter PD meter:
positive displacement
®
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
