Thermal Flow Switches are used in various applications like hydraulics and pneumatics system, circulating water system, run-dry protection of pumps. This switch is operated using a sensor. They are made using premium quality materials and according to the international quality standards. We supply and export these switches that are available in various specifications as per the requirements of the clients.
The flow swtch is 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.
The flow switch is able to monitor and control the liquid flowing of the tube at real time, providing switch output signal and display velocity of flow on multi-LED indicators. The monitoring functions areas follow:
1.Media flowing, reduce/ increase velocity of flowing;
The product could be used for monitoring velocity of flow, flow-cut or prevent pump racing. It is widely used for monitoring velocity of flow and fluid, or protecting the key device when the liquid runoff is failure in various industries.
1. 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.
suitable for different tube diameters;
9.Switch output, control point setting continuously on panel;
10.LED flicker and display flow and switch situation at real time
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.
