FLOW RATE TIME UNITS
(converts flow rates from per
second to other time units) Float 54 Typically delivered in customer
requested units (standard is 3600 for
flow per hour other choices are 1 for
per second 60 for per minute)
NETORGROSS Integer 50 0 = GROSS FLOW, Rate & Total
1 = NET FLOW, Rate & Total
Net Reference Temperature Float 1114 Reference Temperature in
Temperature Units used to Calculate
Net Flow.
Use the units that the system was
delivered in (e.g., degF or degC)
Net Reference Pressure Float 1116 Reference Pressure in Pressure Units
used to Calculate Net Flow.
Use the units that the system was
delivered in. The units maybe one of
the following:
Kg/cm
2
,
PSIG,
bar,
kPa
Kfactor Float 98 See LEFM 240C/220C Installation,
Operation, and Maintenance manual
for table of pulses per unit volume.
When changing to a non-standard k-
factor the desired flow range must
produce an output between these
values:
Minimum Frequency = 3 Hz
Maximum Frequency = 10 kHz
Force a Frequency Output Integer 802 0 = Normal Operation
Any other value outputs a pulse
output at a frequency equal to the
value entered.
