Tubular Sight Glass Used for Observing Liquid and Gas Flow

Tubular gauge glass, also called tubular glass, tubular sight glass and tubular boiler glass, can be divided into standard size and heavy wall size according to the wall thickness. The standard size tubular glass is commonly used in low pressure boiler, tanks and some other low pressure instruments. The heavy wall kind is suitable to high pressure environment, such as crude oil and water, gas flowmeter or acid and alkali containers.

The material of tubular sight glass is soda-lime glass, borosilicate glass and quartz glass. Borosilicate glass and quartz glass can resist acid and alkali and work in high pressure and temperature environment. But for soft environment application, soda-lime glass is the most economic choice.

 The red line in the tubular glass makes the
liquid level more clear for reading.

Features and advantages

• Corrosion resistance 
  Glass material have stable chemical property. We have quartz glass and borosilicate glass for aggressive working environment.
• High working temperature and pressure 
  Our standard size tubular gauge glass is suitable in no pressure and low temperature environment. Our heavy wall kind tubular gauge glass can work safely in high pressure and high temperature environment for a long time.
• We can draw a red line in the tubular sight glass 
  The red line in the tubular sight glass can make the liquid level more clear for reading.
• Precise dimension 
  We can customize the tubular gauge glass according to the required dimension. We can achieve ±0.01 mm tolerance for accurate instruments application.
• Easy to clean 
  The tubular gauge glass can be cleaned easily by water. With suitable cleaning, the tubular gauge glass can be used as long as 10 years.

Application

• Used in tanks or reservoirs for liquid level reading.
• Used in petrol industry.
• Used as water or gas flowmeter.
