GZS type quartz glass tubular level gauge(One) GZS type quartz glass tubular level gauge is of field indicating instrument. The features of mechanics, mechanical, electric and optics of quartz glass tube are superior to nominal glass tube. Furthermore, it is superior to nominal glass tube liquid level gauge because of the action of refraction and reflection, it has bicolor characteristic. And therefore it can be applied to measure fluid level of various kinds of industrial equipments such as pot, tower, tank and box. And particularly apply to measure the high temperature, high temperature difference, high pressure and acid fluid level. And because of the double color indicating action, it can specially affect the high temperature, normal temperature boiler liquid level double color indicating directly. Our quartz glass tube liquid level gauges all adopt SiO2 quartz glass, purity is 99.99%, transform temperature is 1075, compression resisting is 1000MPa(10,000kgf/cm2), factor of expansion is 5.5×10-7. And quartz glass tube, according to the standard of JC225-81, after special dealing, make to transparent quartz glass tube as the meter measuring body. And after the delicate design of meter structure, the gauge has the characteristics of clear display, high ability of resist compression, convenience to install, protect and maintain.quartz glass tubular level gauge is a upgraded products of common glass tubular gauge. (Two) 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. Acording 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 continously and automatically, and brings much convenience to read and record the level digit. 2. technical parameter (1)tube: quatz glass tube, test pressure in less than 13 Mpa.
