Is your recirculation pump working?

 

Is your recirculation system at the correct flow rate?

 

Is your chemical pump injecting into a stopped system?

 

Is your filter clogged?

 

A rare earth magnet is located within the red PVDF float of the new F-300 flowmeters. When the magnet passes through the Alarm Trigger Zone (Hysteresis) of the Sensor Accessory, the built-in contact closure switch sends a signal to external devices.

 

Note: Two alarms can be placed onto one meter to obtain both ‘Flow Switch’ and ‘Flow Sensor’ capabilities. See diagrams below.

 

Voltage	100 VAC or VDC Abs. Max.
Current	0.250 Amp AC/DC Abs. Max.
Power	5 Watts Max.
Contact Configuration	N.O.
Form	A, SPST
Housing Material	PVDF, Black
Load Type	5 feet, 24 wire
*For use with F-300 flowmeters which contain a RED float.

 

Detects if water flow rate is at desired level. A built-in contact closure switch can remotely turn on/off a chemical pump and/or other external devices when flow rate is within desired range. Additionally, this can be used as an alarm signal if flow rate is not within flow range target, potentially indicating a clogged filter, malfunctioning equipment, closed valve, etc.

• With flow rate sensor installed at targeted flow rate, the sensor can detect if your flow is within desired range. The alarm hysteresis window is approx. 10GPM (varies).
