If the mass flow rate drops below 15 g/sec but not below 10 g/sec:
-
The 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 mass flow rate drops below 10 g/sec, both outputs will report zero flow, and 0
will be used in all internal processing.
4.2
Configure volume flow measurement for liquid
applications
The volume flow measurement parameters control how liquid volume flow is measured
and reported.
The volume flow measurement parameters include:
Volume Flow Type
Volume Flow Measurement Unit
Volume Flow Cutoff
Restriction
You cannot implement both liquid volume flow and gas standard volume flow at the same time. You
must choose one or the other.
