Product Details

Description

 

Liquid Flow Switches are Single - Pole, Double - Throw (SPDT) flow switches that are used in liquid lines carrying water,ethylene glycol,or other liquids not classified as hazardous, They can be wired to energize one device and de-energize another device powered from the same source when liquid flow either exceeds or drops below the set flow rate.


Feature

 

  • LQY series liquid flow switch is used to monitor the flow change
  • Renovated SPDT micro-switch ensure the reliable switch function
  • Max temperature of medium 120℃
  • Liquid pressure up to 1Mpa
  • 3 stainless steel blades for diameter of 25-75mm pipeline
  • 6 additional blades for 100-150mm pipe
  • Protection type IP54
  • Various connections are available on request
  • Max working pressure 13.5Bar
  • Electrical loading AC250V 10A
  • CE approval
