Enter the value of delta P at which the unit will begin using the hi
range delta P pressure transmitter signal.
Input:
Number with floating decimal point: 0.000...999999
Display: 0.000 in H2O
SWITCH UP DP
Enter the value of delta P at which the unit will begin using the lo
range delta P pressure transmitter signal.
Input:
Number with floating decimal point: 0.000...999999
Display: 0.000 in H2O
SWITCH UP DP
Enter the low flow cutoff. This is used as a switchpoint for creep
suppression. This can be used to prevent low flows from being
registered.
Input:
Number with floating decimal point: 0.000...999999
Display: .000 ft3/h
LOW FLOW CUTOFF
Enter the K-Factor of the flowmeter.
Note:
• The K-Factor is expressed in pulses per unit volume (as
defined by "total units")
Input:
Number with floating decimal point: 0.001...999999
Display: .000 ft3/h
LOW FLOW CUTOFF
Enter the inlet pipe diameter or bore for the piping section upstream
of the flow measurement device.
Input:
Number with floating decimal point: 0.001...1000.00
