•
mA Output Process Variable for the primary mA Output:
Gas Standard Volume Flow
Rate
•
Frequency Output Process Variable:
Gas Standard Volume Flow Rate
•
mA Output Cutoff for the primary mA Output:
10
SLPM (standard liters per minute)
•
Gas Standard Volume Flow Cutoff:
15
SLPM
Result: If the gas standard volume flow rate drops below 15 SLPM, the volume flow will be
reported as 0, and 0 will be used in all internal processing.
Example: Cutoff interaction with mA Output Cutoff higher than Gas Standard Volume

Rate
•
Frequency Output Process Variable:
Gas Standard Volume Flow Rate
•
mA Output Cutoff for the primary mA Output:

•
Gas Standard Volume Flow Cutoff:
10
SLPM
Result:
•
If the gas standard volume flow rate drops below 15 SLPM but not below 10 SLPM:
-
The primary mA Output will report zero flow.
-
The Frequency Output will report the actual flow rate, and the actual flow rate
will be used in all internal processing.
•
If the gas standard volume flow rate drops below 10 SLPM, both outputs will report
zero flow, and 0 will be used in all internal processing.

Overview
Flow Direction controls how forward flow and reverse flow affect flow measurement and
reporting.
Flow Direction is defined with respect to the flow arrow on the sensor:
•
Forward flow (positive flow) moves in the direction of the flow arrow on the sensor.
•
Reverse flow (negative flow) moves in the direction opposite to the flow arrow on
the sensor.
