WGLFT series buoy level gauge, interface gauge

■ General

WGLFT series float type liquid level gauge is a new type of liquid level measuring instrument developed by our factory based on foreign advanced liquid level measuring technology. It is suitable for continuous measurement of liquid level in various atmospheric pressure and pressure vessels in petroleum, chemical, electric power, metallurgy and other industries. Its output is a 4-20mA DC current signal proportional to the change of liquid level, which is used together with display, recorder, regulator and computer to realize the liquid level measurement and control in the process of production.
