Rotor Flow Sensor

Home - Sensing - Flow Sensors - Rotor Flow Sensor

General Purpose rotor flow switch

Magnetic rotors are propelled proportionally to measure gas or liquid flow and no flow within the sensor to give continuous monitoring. Available as NO /NC and changeover the sensor operates without the need for a standby power supply and the self clean function is designed to reduce the need for maintenance but system filtration is recommended as well. These sensors are primarily designed to work with water but can be adapted to work with other fluids / gases, please contact us for chemical compatibility. Applications include water treatment, cooling systems, chemical processing, agriculture and food and beverage production.

  • Reed type magnetic activation
  • Zero standby power consumption
  • Low flow activation
  • Minimal flow restriction
  • Partical self clean function
  • Customizable configurations
  • NO / NC versions available

Max operating flow 12 litres / min.

Minimum pressure 0.005 MPa 

Maximum pressure ≤1.5Mpa

0°C… 100°C
