Water Flow Switch NK-01D series

Principle Characteristics

Mechanical flow switch with built-in spring-supportedMechanical flow switch with built-in spring-supportedbaffle. When the flow reaches the prefabricated value, the mechanical structure triggers the microswitch.

SPDT output, small pressure loss, mechanical part and electronic part complete isolation/flow range is large,easy to adjust and set, switch factory standard with a set of baffle (5 pieces), can be flexibly combined according to the situation, suitable for a variety of pipelines, switch has high reliability and good repetition, strong anti-pollution abilitybaffle.
