The Pressure module (PIM) provides the FB107 with pressure
inputs and pulse counts for AGA7 flow calculations with AGA8
compressibility. Each FB107 supports one PIM, which can have up
to two pressure transducers.
When used with a linear meter input , the pressure transducer in
the PM measures pressure while a designated I/O module in the
FB107 measures pulses from the turbine meter.
Note:
Turbine pulse inputs must go to the PI of an I/O module,
with a pre-amp to amplify the signal.
The primary inputs for AGA7 flow measurements are pulse input
counts, static pressure, and temperature. Pulse input counts come
from the linear meter input; static pressure (including auxiliary
pressure) inputs come from the pressure transducers; and
temperature readings come from an RTD probe. The FB107 reads
inputs in the following sequence at the following frequencies:

Pulse counts are read once per second.

Static pressure is sampled once per second.

Temperature is sampled and linearized once per second.
6.3.1 Installing/Removing a Pressure Module
Note:
The PIM is a factory-installed option for the FB107, and is
bolted onto the FB107’s exterior case. In normal operation,
you should not have to install or replace the module.
