Product 3D Image Get couponsBased on the thermal principle, the sealed probe contains two resistors, one of which is heated to act as a detection resistor and the other unheated to act as a reference resistor. As the medium flows, the heat is removed from the heated resistor and the resistance value is altered, with the difference between the two resistances being used as a basis for determining the flow rate. No moving parts, maintenance-free, easy to install, one model for a variety of pipe diameter requirements, switching volume continuously adjustable, very low pressure loss, compact structure, LED display flow trend and switching status.
Pneumatic and hydraulic dual purpose, low flow rate alarm, can be used for pneumatic and hydraulic systems, can be used for circulating water, cutting fluid and lubricating oil cut-off detection, and pump idling protection.
For vertical installation, it should be installed on the pipe section flowing from bottom to top.
When mounted horizontally, the probe should be kept away from air and sediment.
