220SS0005-1211 insert-style liquid flow sensors with stainless steel sleeves fit pipe sizes from 3” to 40” (77 to 1016mm). Sensor output is a pulse train whose frequency indicates flow rate. Used in conjunction with a compatible flow monitor or transmitter, these non-magnetic flow sensors provide an accurate reading of the rate of liquid flow, as well as total accumulated flow in indoor or protected areas.


  • Measuring liquid flow rates
  • Accounting for total accumulated flow


  • Six-bladed impeller design with a proprietary, non-magnetic sensing mechanism...high accuracy and repeatability
  • Forward-swept impeller is less prone to fouling by water-borne debris...reliable performance with minimal downtime
  • Signal can travel up to 2000 ft (609m) between the sensor and the display unit without amplification
  • Supplied with 20 ft (6m) of 2-conductor 20-AWG UL type PTLC cable (105°C rated)
  • Sensors of similar type are interchangeable, so there is no need for recalibration after servicing or replacement...quick install and fast maintenance
