Performance Data - Reed Style Pulser

Pulsers: RD 01 - 02 - 011 - 022 

Performance Data

Low Frequency pulsed output
Type: REED-01/02

Description: The REED-01/02 is a 2-wire low frequency volt-free contact closure pulse for use with the WP/Dynamic Water Meters.  REED-01 is for use with Cold Water Meters; The REED-02 is designed for use with the Hot Water Meters, but is suitable for use in cold water applications if needed.  This type of pulser is used for with pulse counter, flow rate indicators, etc.

Principle:  A REED switch is encapsulated within the counter and is switched by permanent magnets fitted within the counter mechanism.  

NOTE: Continuous contact can occur when the water flow stops.  Connected devices must be suitably protected.
