Flow Switch (CX-FS) for Water

Product Description

We produce various flow swich and widely used for gas and liquid. and below is the mainly model.
 

Principle Based on the principle of thermal theory, there are two resistances in the closed probe. One resistance was heated and regarded as detected resistance, the other one was heated and regarded as standard resistance. When the medium is flowing, the heat on the heated resistance will be taken away and the resistances' value will be changed. The differential resistances value is the basis of determining the flow velocity. Feature 1, No movable parts. 2, Maintenance free. 3, Easy installation. 4, Suitable for variable diameter demand. 5, Switching value can be adjusted continuously. 6, Extremely low pressure loss. 7, Compact structure. 8, LED indicator display flow trend and switch state.
