Quartz Tube Double Color Level Gauge

Short Description:

Color quartz tube level gauge is the use of natural light in the liquid fold, reflection principle, with the help of red, green, in the measurement, the liquid phase display green, gas phase display red. Due to the large contrast of liquid and gas phase display, the instruction is clear and clear, so it is more favorable for remote operation and night inspection. Widely used in petroleum, chemical industry, electric power, metallurgy and other industries of all kinds of transparent liquid containers and boilers, such as water, gasoline, liquefied gas, liquid ammonia, propane, propylene, aromatic, acid and other oil and chemical raw materials level measurement. At the same time for the interface measurement of two different medium densities, a three-color interface quartz tube level gauge can be selected. Three-color interface quartz tube level gauge is designed by using the principle of buoyancy and gravity difference, quartz tube in the small float suspended in two kinds of medium part of the boundary, because the float is black, the upper and lower part of the liquid level color is different, so the display eye-catching. The problem of indistinguishable interface between two kinds of mixed media in petrochemical production

    The Quartz Tube Double Color Level Gauge is a secondary instrument that shows the liquid level position directly by using the optical principle. It can be widely used in the steam drum and storage of high and medium pressure boilers. The liquid level meter, in the coexistence of water cars, the water phase is green, the vapor phase is red, the water level boundary is very obvious for observation; When the water is full, the whole string is green, when the steam is full, the whole string is red, completely overcome the general liquid level meter can not be resolved when the water or steam is full, so as to cause serious accidents. At the same time, the table also has the advantages of simple structure, convenient maintenance, safety and reliability
    Structure principle of quartz tube type two-color level gauge
    Quartz tube two-color level gauge is composed of upper valve, lower valve, body, blowdown valve, balance tube and lampshade.
    In addition to manual full opening and full closing of upper and lower valves, there are one insurance seat and one insurance ball inside the valve body. When the quartz tube is damaged accidentally, the insurance ball will automatically close the upper and lower channels of the table body under the impact of high pressure soda at high speed. Until the upper and lower valves are closed manually. The reset of the insurance ball is achieved by balancing the pressure and making the weight of the insurance ball. Therefore, there will be no false water level and other adverse phenomena. At the same time, this level gauge in addition to a special protective cover, the level gauge body itself is an excellent protective cover, so it is very safe and reliable.

  • *Borosilicate glass

    Borosilicate Glass for circular sight glasses or tubular sight glasses
    Borosilicate glass is a kind of glass with silica and boron trioxide as the main glass-forming element. Borosilicate glasses become famous for having very low coefficients of thermal expansion, making them more resistant to thermal shock than soda-lime glass. borosilicate glass is fit to be used in sight glass lens,
    Borosilicate glass is ultra and clear glass with good thermal and chemical properties and outstanding transparent
