5.4 Decimal Places
Decimal places are separately adjustable for Total, Accumulated Total, and Rate from zero to
three decimal places. The decimal places setting for Rate will set the available decimal places
in the analogue output set point. The decimal place settings for Total and Accumulated Total
do not influence configuration of the pulse output.
5.5 K-Factor Entry
The K-factor entry screen allows entry of up to 7 whole numbers and 4 decimals, however
only the first 7 significant digits are used by the software in calculating totals. When entering
the K-factor screen not all available digits are shown; moving the curser to the right will show
the remaining available digits. Note that when different engineering units are configured for
Total and Rate, the K-factor should be entered in the engineering units which are selected for
Total.
5.6 Input Type Configuration
The input type can be selected from the following; Reed switch, NPN, PNP, or Coil. The
following table should be referenced when selecting the correct software setting for your
flowmeter. Instruments delivered integrally mounted to a flowmeter will have this
parameter factory set and do not require user adjustment.
Sensor Type Used in:
Reed Switch
REED 120Hz
NPN Sensor
DP Meters – Hall Effect
NPN 1.2kHz
PNP Sensor
Other manufacturer’s
Flow Meters
PNP 1.2kHz
DP Meters - Voltage Pulse
5.7 Non-Linearity Correction
Non-linearity correction (NLC) allows the instrument to correct for known inaccuracies in a
flow-meter, thereby improving the overall measurement accuracy, and in many cases
increasing the effective flow range of the measurement system. Non-linearity correction can
be used on battery power however battery life will be reduced according to usage.
