Signet 2537 Flowmeter
Mode
This function is available on
these versions of the 2537:
PULSE TOTAL Output = Input pulses ÷ (K-Factor × P-Factor)
TOTAL is a traditional pump pulser function. This selection will
allow the entry of a K-Factor to de¿ ne a volumetric unit, then set
a P-Factor to de¿ ne the number of volumetric units required to
generate one pulse out.

In PULSE DIVIDER mode the P-Factor divides:
The pulse stream from the paddlewheel sensor will be divided
by the P-Factor. The resulting frequency is output through a
relay.
In PULSE TOTAL mode the P-Factor multiplies:
The pulse stream from the paddlewheel sensor is divided
by the K-Factor MULTIPLIED by the P-factor. The resulting
frequency is output through a relay.

Select DIVIDER or TOTAL operation.
The factory setting is TOTAL.
PULSE DIVIDER Output = Input pulses ÷ P-Factor
DIVIDER allows you to set a scaling value (P-Factor) from
1.0000 to 99999.
Example: If the P-Factor is set for 2, then the 2537 will output
one pulse for every 2 pulses received from the sensor.
This selection enables the output frequency to be scaled down
to match associated equipment capabilities.
When using the PULSE DIVIDER output, associated equipment
must divide the K-Factors in this manual by the P-Factor for
correct calibration.
Example:
Set the Total Pulse output so there is one pulse out for each
2 gallons that passes the sensor if the K-Factor is 3.0.
1.
K-Factor = 3.0 (pulses in per gallon)
2.
P-Factor = 2 (gallons out per pulse)
