Manufacturer of liquid level switch controllerThe UQD series float level transmitter can display on site. It converts the displacement of the magnetic float with the change of liquid level into a 4-20mA two-wire standard signal output. The working power supply of the transmitter is 24VDC. Suitable for online measurement and control of various water supply and drainage projects such as petroleum, chemical, metallurgical, environmental protection, etc. (equipped with various regulating instruments).

structural characteristics

The UQD series float level transmitter consists of magnetic float, measuring conduit, measuring element, circuit unit, junction box housing, and installation components.
