Series CFS Turbine Flow Sensors
1/4”, 3/8”, 1/2" Pipe Size, 0.8-25 LPM, Reed Switch Output
DESCRIPTION
Series CFS Turbine flow sensors are designed for water and compatible clean fluid flow measurement. They are a very economical choice for application where the accuracy, materials of construction and 500,000 liter approximate life rating of the sensors are acceptable.
A magnet imbedded in the turbine (CFS2000 &3000A) or a PA plastic encased magnet turbine (FS4400) closes a hermetically isolated reed switch when in proximity. Sensor calibration factors are provided to convert pulses to flow rate.
Common applications include water treatment systems, filter monitoring, water dispensing, cooling loops and more.
