2.5 Gas
Flow
Volume
The GTFM can also be used to monitor accumulated gas flow and to provide an
indication when the volume in a gas cylinder has reached a programmed minimum
limit. The GTFM will calculate the volume of gas used based on the measure flow
rate. If the user programs the initial volume in a cylinder, and the minimum volume
for safe operation, the GTFM will indicate when the estimate minimum volume has
been reached. The GTFM will flash a
"G"
on the display when the estimated cylinder
volume has decreased below the programmed minimum. Setting the starting volume
“V” to 0 disables the function.
NOTE: THE LOW GAS VOLUME FAULT WILL NOT ACTIVATE THE FAULT RELAY BUT
WILL INDICATE THE FAULT CONDITION BY FLASHING A "G" ON THE
DISPLAY SCREEN.
