PD6928 Ex-Proof & I.S. Loop-Powered Flow Rate/Totalizer
Instruction Manual

Pulse Output (
PULSE
)
Pulse outputs may be assigned to output the rate, total, or grand total at a programmable factor. If the output is
assigned to rate, the factor is a multiplier that determines the number of pulses generated based on the rate. For
example, if the meter display shows 100 gallons/second and the factor is set to 2, the number of pulses generated
per second would be 200. If the output is assigned to total or grand total, the k-factor corresponds to the number of
pulses generated per unit of measure. For example, if the k-factor is 0.001 and the units are gallons, one pulse will
be generated for every 1,000 gallons. The maximum frequency is 1,000 Hz.
Setting output 2 to quadrature will duplicate the other open collector output, but lag by 90 degrees out of phase. The
other output should be programmed as desired for the quadrature output function and must be a pulse (
PULSE
)
output selection. The quadrature maximum frequency for both outputs is 500 Hz.
The
TEST
option will output a fixed number of pulses per second based on the
FREQ
value entered.
