For Pressure
The upper and lower calibration points indicate the upper and lower pressure value that will
correspond the upper and lower scale value respectively.
Flow = (scale EU100 – scale EU0) * sqroot(( DP – Cal Lower) / (Cal Upper – Cal Lower)) –
scale EU0 for DP > cal Lower
Flow = (scale EU100 – scale EU0) * sqroot((Cal Lower - DP) / (Cal Upper – Cal Lower)) – scale
EU0 for DP < -cal Lower
Flow = 0 for DP < abs ( cal lower)
Where scale EU100 and scale EU0 are in flow units and Cal Upper and Cal Lower are in
pressure units.
The square root function is automatically employed for conversion from pressure to flow scale
units. Calibration units are always in pressure units.
