Principle, structure

Mechanical flow switch. The stopper with built-in spring support triggers a micro motion switch when the flow rate reaches the preset value.

characteristic

Online installation, minimal pressure loss, good repeatability, anti fouling ability, precise switch settings achieved through knobs. The mechanical and electronic parts are safely isolated.

application

Gas liquid dual-use type, suitable for industrial automation/mechanical equipment/air compression industry/refrigeration and air conditioning pipelines with a diameter of ≤ 50mm.

Performance Overview

Flow switch, brass (stainless steel) valve body. The internal components such as the baffle, corrugated tube, and support frame are made of stainless steel. Applicable media: water, ethylene glycol solution, oil, air. Maximum working pressure 25 bar. Medium temperature -30... 350 ℃. Power supply: 250V, 3A. Protection level IP54. Suitable for pipe diameters DN15~DN50

Parameter Table

Note: The above parameters were obtained by installing the switch vertically in a horizontal pipeline and testing it with 20 ℃ water as the medium. The switch material for the above model example is 316L stainless steel (with bronze material optional)
