The glass plate level gauge is an in-place direct-reading instrument for direct indication of the height of various tanks and pressure vessels. The operator can judge the operation status of the container according to the reading of the instrument at the scene once, and ensure the safe and stable operation of the device and reduce the unnecessary loss. Widely used in petrochemical, power, pharmaceutical, paper and other industrial areas of liquid level measurement.

System composition and principle
Glass plate level gauge by the body, gland, glass, sealing components, vapor-liquid valve, and sewage valve and other components. Glass plate level gauge is divided into transmission and reflection, transmission level gauge body before and after a piece of glass, by the front and rear glands by bolts tighten the seal, through the light projection principle display level; reflective level gauge with compression U-type plug will be gland, glass, sealing components, the body connected to form a sealed structure.

Glass plate level meter with monochrome and two-color display can be selected.

Transparent monochrome level gauge is through the flat glass can be intuitive to see the liquid level or interface, easy to observe the liquid level or boundary.

Transparent two-color level gauge with 90 ° slot glass, gas phase is red, liquid phase is green, can clearly observe the liquid level line.

Reflective monochrome level gauge with multi-stripe glass, gas phase is white, liquid phase is black, can clearly observe the liquid level line.

Reflective two-color level gauge with 90 ° groove glass, according to the principle of optical reflection, so that the gas phase was red, liquid phase was black, can clearly observe the liquid level line.



Technical advantages
Glass plate level score for blind and non blind two kinds of structure, no blind structure of glass plate has same visual range and center level meter has the advantages of easy observation, visual range, the liquid level observation more accurate.

Glass plate level meter Vapor valve are equipped with safety protection device, when there is accidental leakage, the protection of steel ball in the container under the pressure of the automatic sealing channel, improve safety. For the relatively strong corrosive chemical media display level, our company uses a corrosion-resistant glass plate level gauge, in the glass plate and the measured liquid with mica between the mica has a strong corrosion resistance and high temperature performance , Thus protecting the glass plate, to ensure long-term, stable and reliable operation of the device.

When the operating temperature of ≥ 200 ℃, the glass plate with aluminum silicate glass and lined with mica, aluminum glass has good chemical stability, strong mechanical strength and low coefficient of thermal expansion, suitable for high temperature environment, to ensure that The device is safe and reliable in high temperature environment.

I glass plate level meter company has formed a series of products, according to different working conditions can be equipped with the corresponding function of the glass plate level gauge.

Frost type
It is suitable for measuring liquid level below 0 degrees centigrade, and low temperature liquid often causes frosting or icing on the surface of liquid level meter, which makes it impossible to observe liquid level. Under this condition, the glass plate liquid level gauge with frost proof function can be adopted, that is, the propylene base protective window is added on the visual window, and the heat meter is added to the liquid level meter to observe the correct liquid level through the protective window.

Jacket type
Suitable for measuring high viscosity or low boiling liquid levels. The heating function is to install the jacket on the glass plate level gauge. For high viscosity easy to solidify the liquid, in the jacket into the steam or high temperature liquid, so that the internal temperature of the level gauge and the measured device within the temperature consistent, so as to determine the exact level. For low boiling point boiling water, in the jacket through the cooling water to achieve a stable role in the liquid surface, and thus to ensure the accuracy of the measurement level.

Thousands of birds
The glass plate level gauge window side by side arranged alternately, so that the measurement range is completely visible without blind spots, to avoid the blind spot and can not accurately observe the liquid level of the situation.

Wide diameter type
Applicable to a strong bubble liquid, the use of tubular structure, the body cavity area is large, can make the fluctuating liquid level more stable, to avoid the fluctuation caused by the measurement of liquid surface error, so that the observation is more clear, more accurate measurement, In the viscosity of the liquid, the installation center distance ≤ 6000mm.
