For higher resolution (reading in gallons and tenths, gallons and hundredths,
etc.) multiply by 10 for tenths; by one for hundredths. The number dialed into
dipswitch S5 corresponds to the number of digits to the right of the decimal point.
Example:
Flowmeter “K” Factor = 230
CF= .004348
Desired display = gallons and tenths
Multiply by = .04348
S4 = 1
Factor Switches = 4348; S3 = 4, S2 = 3, S1 = 4, S0 = 8
Decimal point = S5 = 1
To adjust the calibration factor to reflect the turbines actual response to the
operating conditions apply the following formula:
Field Correction
New Calibration Factor = Actual Total
Meter Total
X Calibration Factor
Example #2:
Actual Total = 50
Meter Total = 52
C.F. = .004348
50/52 X .004348 = New Calibration Factor
.9615 X .004348 = .0041806
Insert 4181 into S3 – S0 respectively
In the above example .9615 denotes that the meter is operating .385% fast and
multiplying the present calibration factor (.004348) by the ratio of Actual Total:
Meter Total (.9615) reduces the calibration factor 3.85%.
Assume that rather than gallons, liters are the desired engineering unit.
Calibration Factor – Change of Calibration Engineering Units
Example #3:
K-Factor = 230 pulses per gallon
Liters = 3.785 per gallon
3.785
230
= Calibration Factor
.01646 = Calibration Factor for display of liters
