WGLF series magnetic level gauge

■ General

WGLF series magnetic float level gauge is widely used in petroleum, chemical industry, pharmacy, metallurgy, sugar making, paper making, power, water treatment, shipping, environmental protection, boiler and other industries to detect and control the medium level in various tanks, tanks, towers and other containers (equipment). The liquid level gauge has incomparable advantages over the traditional glass tube (plate) liquid level gauge. Because its indicating part does not contact with the measured medium, it can achieve high sealing. It is more reliable and safe for high-temperature, high-pressure, toxic, harmful and strongly corrosive media.

The magnetic float level gauge takes the float as the measuring element, and transmits the liquid level linearly to the field magnetic turnover indicator through the magnetic coupling of the magnetic steel, so that the indicator can clearly indicate the height of the liquid level. The liquid level meter can be equipped with a liquid level alarm and a liquid level remote transmission device. The liquid level alarm realizes the upper and lower limit control, limit alarm and accident interlock of the liquid level. The remote transmission device of the liquid level linearly converts the change of the liquid level into a DC 4~20mA current signal output, which is used to connect with the digital display instrument or computer system to achieve remote liquid level display and control.

■ Product characteristics
