Square root output
When a flowmeter of orifice or nozzle is used to measure flow, Square root computation
is applied to convert differential pressure voltage signals into flow-rate signals. Low Cut
value range = 0.0~5.0% (value of Ch1 < value of Ch2)
Example) Linear Voltage = 0.0 ~ 10.0, Range=0.0~1000.0,
1) Lowcut=0.1%(0.01V limit)
if input value = 1.0,
0.1% : 1.0 = X : 1000.0,
∴
X =0.01V
