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.
-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.
