PGEN

The [PGEN P/Unit Volume] menu cell entry controls a digital output pulse function and is available in
Custody Transfer units only (designated by a "C" in their part number). It allows the assigning of PGEN
digital signal pulses per unit of volume. For example, 1000 output pulses per cubic foot of gas.
NOTE: The unit of volume is determined by the Volume Units initially selected from the [Total
Volume Units] menu cell option list (refer to paragraph 4.6.6).
To assign PGEN output pulses:
From the [Span Data] menu press
From the [PGEN P/Unit Volume] menu cell, press
Use the numeric keys to enter the desired number of PGEN pulses per unit volume.

Max Flow

The [Max Flow] menu cell stores the maximum range for the flow rate output (Vfo). It can be a positive
or negative value. Enter the data using the flow rate units you selected. This entry also spans the un-
signed flow variable (Vfab) as noted above.
Vs is the sonic velocity in meters-per-second (m/s) of the flowing gas.
The min. and max. Vs entries establish the Vs span. Max Vs (m/s) defines
100% of span. The Min Vs (m/s) defines 0% of span.
Vsg is the inferred operating specific gravity of the gas. The min. and
max. Vsg entries establish the Vsg span. Max Vsg defines 100% of span
and Min Vsg defines 0% span.
