Overview
mA Output Cutoff specifies the lowest flow rate that will be reported through the mA
output. All flow rates below the specified value are reported as 0.
mA Output Cutoff is applicable only when mA Output Source is set to a flow rate variable.
It is applied to all flow rate variables: mass flow rate, liquid volume flow rate, gas standard
volume flow rate, and so on.
Procedure
Set mA Output Cutoff as desired.
Set mA Output Cutoff in the measurement units used for the process variable. If you
change the measurement unit, mA Output Cutoff is adjusted automatically.
• Default: 0
• Range: 0 or any positive value
Tip
For most applications the default value of mA Output Cutoff should be used. Contact customer
service before changing mA Output Cutoff.
Configuration and Use Manual
Under conditions of forward flow, for flow rates between 0 and +100 g/sec, the mA
output varies between 12 mA and 20 mA in proportion to (the absolute value of) the
flow rate.
Under conditions of forward flow, if (the absolute value of) the flow rate equals or
exceeds 100 g/sec, the mA output is proportional to the flow rate up to 20.5 mA,
and will be level at 20.5 mA at higher flow rates.
Under conditions of reverse flow, for flow rates between 0 and −100 g/sec, the mA
output varies between 4 mA and 12 mA in inverse proportion to the absolute value
of the flow rate.
Under conditions of reverse flow, if the absolute value of the flow rate equals or
exceeds 100 g/sec, the mA output is inversely proportional to the flow rate down to
3.8 mA, and will be level at 3.8 mA at higher absolute values.
