Quartz tubular type level gauge are specially used for high temperature to 450°c and high pressure fluid level measuring.
GZS type bi-color quartz glass tubular level gauge
1. function and work principle
quartz glass tubular level gauge is widely used in petroleum, chemical, industries, electricity, metallurgy, papermaking etc. to measure transparent liquid level in tank and boiler.
GZS type bi-color quartz glass tubular level gauge. According to standard GB 9658-88 and HG/T2483-93 by well-designed and take full advantage of optics principle. The color in gauge tube is green for liquid and red for non liquid. And the color changes according to liquid level continuously and automatically, and brings much convenience to read and record the level digit.
