Electronic flow sensor
FS-FR11 series Electronic flow sensor , also known as differential thermal flow sensor and Thermal flow sensor . The set range can be 1-20m/s . Have relay output (230VAC.4A). Suitable for different kinds fluid .Concise and direct indicator ,and with high reliable .
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 .
-No movable parts .
-Suitable for variable diameter demand .
-Switching value can be adjusted continuously.
-Extremely low pressure loss .
-Compact structure .
-LED indicator display flow trend and switch state .
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 .
