Description
This calculation is used to convert, for example, a differential pressure signal from a
throttlingflowmeter
suchasanorificeandnozzleintoaflow-ratesignal.Thereisno
hysteresis for low signal cutoff point.
Output = Input
The slope equals “1” at levels below
the low signal cutoff point (A.SR=1).
The slope equals “0” at levels below
the low signal cutoff point (A.SR=2).
