Electronic flow sensor (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 .
