Product Description
Quartz Glass Tubular Level Gauge
(One) Outline of quartz glass tubular level gauge
Quartz glass tubular level gauge is of field indicating Level instrument.
The features of mechanics, mechanical, electric and optics of quartz glass tube Make it superior to ordinary glass tube liquid level gauge, it has bicolor characteristic and can working at high temperature and high pressure conditions and acid fluid level. And therefore it can be applied to measure fluid level of various kinds of industrial equipments such as boiler, tower, tank.
Our quartz glass tube liquid level gauges all adopt SiO2 quartz glass, purity is 99.99%, transform temperature is 1075º C, 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.
(Two) bi-color quartz glass tubular level gauge
1. Function and work principle
Quartz glass tubular level gauge is widely used in lines of petroleum, chemical, industries, electricity, metallurgy, papermaking etc. To measure transparent liquid level in tank and boiler.
Bi-color quartz glass tubular level gauge. 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.
2. Technical parameter
(1) tube: Transparent quartz glass tube, test pressure in less than 13 MPa.
(2) gauge Material: A3 carbon steel or 1Cr18Ni9Ti SS304, PP
(3) Measure range: 300~3000mm,
(4) Fluid working temperature: -20º C~180º C, 180º C~450º C
(5) Gauge working pressure: ≤ 10MPa
(6) Flange: DIN, ANSI, JIS selectable
Also can produce according to customer's requirement specially.
(Three) Install, service and maintenance
1. Install
(1) When the products leave the factory, every part of the gauge pressure had been tested of 1.5 times of the marked pressure. As to prevent damage please don't remove quartz glass tube.
(2) Bi-color quartz glass tubular level gauge is of precision meter, so please be carefully when transport, carry, open case and install the meter, and also to avoid the quartz glass tubular, red and green glass damaged.
2. Applications
(1)When the level gauge has been installed to the container, open the upper and lower valve slowly, and the liquid flow in the tube and wash the wall. If the liquid is high temperature, the quartz glass tube must be warm-up for half an hour to prevent it bursting.
(2)When view the level, you must stand in front of the level gauge. And then the level you see is the actual level.
(3)When liquid flow in the container or the pressure rising in it, the bi-color may be not quite clear, this phenomenon is temporary which is because of the unclear liquid or unstable pressure. So the liquid level will be indicating clearly when the pressure is stable.
