Select Setup item:
Flow input?
NOTES
Linearize
16 Point? Enter Point
Actual 01? Actual 01? 0.000
K-Factor 01?
1 Gas compressibility
Z Factor? Enter the compressibility factor of the gas being
measured
2 Specific gravity
Gravity? Enter the specific gravity constant calculated at
standard or the Base Reference Temperature for the
product being measured
At input = minimum
Lo flow? Enter the flow value at which the analog input is
lowest (i.e. no flow = 4.00mA. Enter 0)
At input = maximum
Hi flow? Enter the flow value at which the analog input is
highest (i.e. 300 m
3
/hr = 20.00mA. Enter 300)
Low flow
Cutoff? Enter the lowest flow value below which any
calculations are unnecessary. For example, a small
leakage when valve is closed to be ignored
3 Thermal Expansion
C(X10E-6)? Enter the Thermal Coefficient of Expansion for the
liquid being measured
4 Mean
Spec Heat? Enter the constant value for the ability of the liquid to
retain heat
Flow alarm set point
Lo alarm? Enter the low compensated flowrate value at which
the flow alarm relay will activate
Flow alarm set point
Hi alarm? Enter the high compensated flowrate value at which
the flow alarm relay will activate
