KFR = 6000/(X Pulses/Engineering unit) (for units/minute)
Locate the X Pulses per Engineering Unit in the calibration sheets of the flow transmitter. It is best to use
numbers larger than 100 but less 9000.
The generic K‐factors for the most common AW‐Gear Meters transmitters are:
Transmitter KFR cc/min KFR Gal/min KFR Oz/min
ZHM‐01 142.0 .0375 4.80
ZHM‐02/1 720.0 .1915 24.51
ZHM‐02 1363. .360 46.00
ZHM‐03 3448. .911 116.6
HPM‐15 720.0 .1915 24.51
HPM‐20 1363. .360 46.00
HPM‐30 3448. .911 116.6
As these are generic K‐factors, consult the calibration sheet supplied with the flow transmitter for the
most accurate information.
USED IN: All modes.
RELATED VARIABLES: DP for Rate A KFR (only in OPTO communication).
HEX ADDRESS: 00E2 HEX ‐‐‐‐> same address used in EMO‐2000.
BYTES: 2 Bytes DEFAULT: 720
ASC form COMMAND: reading = 106; writing = 506; E is with decimal point. N is just the
numeric value.
K‐Factor for Total A KFT (including the decimal point)
The KFT‐factor scales the display to the incoming amount of pulses on channel A, which is on pin 4. Enter
the decimal point in ASC‐form communication. If the OPTO type communication is used, then you must
enter the decimal point separately.
The formula for calculating the KFT value is:
KFT = 10000/(x Pulses/Engineering unit) (for pulses)
The figure X Pulses per Engineering Unit can be found in the calibration sheets of the flow transmitter. It
is advisable to use numbers bigger than 100 or less 9000.
The generic K‐factors for the most common AW Gear Meters transmitters are as follows :
