The Series PWD Pulse Divider is designed for pacing electronic metering pumps. The enclosed rotary switch setting mechanism can be manually set to any number from 0 to 9999 pulses. Once the divider has received the set number of pulses from the meter, it outputs one pulse to stroke the pump. The PWD is also useful in boiler and cooling tower feed and bleed operations, and for lowering frequency output of high frequency meters. The PWD is available in two different housings, one is an enclosure that can be mounted near the pump, and the other is a watertight housing for mounting on the meter.
