Electronic Flow Switch (Thermal differential type)
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 .
Feature1,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 .
Application Suitable for the gas and liquid measurement . Can used for pneumatic and hydraulic systems, flow monitoring for recycled water, cutting fluid and lubricating oil , the protection of pump’s run idle .
