Most Accurate Control By Electronic Thermal Mass Water Flow Switch

                                    -----------We are gold supplier in 9 consecutive years
     CX-FS series Electronic thermal mass  flow switch , 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 .
     The Principle of electronic thermal mass flow switch 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 .




Application:
gaseous /liquid
The flow switch for ground-source heat-pump is mainly applicable to industrial automation/mechanical equipment/air compressing industry/ refrigeration and air-conditioner. The magnet not contact with flowing water, so can normally work in sewage discharging system.
