Thermal Flow Switch
When the fluid flows,the heat of detecting resistance will be taken away,resistance is changed.the differential resistance value is used as the basis of flow velocity.
Feature
1) No moving parts,maintenance free,easy installation,a model can be suitable for a variety of pipe diameter.
2) Adjustable setting point of flow switch,extremely low pressure loss,compact structure.
3) LED light shows the flow trend and switch state.
