Reflex Gauge Glass For Observing Liquid Flow And Level - China

price: contact company for price

Round sight glass, also called round gauge glass and sight glass disc,

commonly uses the material of soda- lime glass, borosilicate glass,

aluminosilicate glass and quartz glass. We suggest different material

according to environmental conditions, such as temperature, pressure,

acid and alkali.

Soda- lime glass working temperature is up to 230 °C, but it is the most inexpensive material. Borosilicate glass is particularly used in aggressive environment, such as acid and alkali. The working temperature is up to 400 °C. Aluminosilicate glass can resist acid and alkali better than borosilicate glass and the working temperature can reach 650 °C. Quartz glass is the best material, whose working temperature can reach 1100 °C.

Round gauge glass is commonly used in industry, chemical, petrol and medicine pipes and flanges for observing the liquid flow and liquid level.
