Quartz glass tube liquid level gauge is a local direct-reading meter and has applied thermostable, high pressure resistance quartz glass tube. It could indicate the liquid level in tanks with high temperature, high pressure and caustic liquid directly. The quartz glass tube is well protected by the metal housing and well sealed to ensure safety.
Bi-color water gauge consists of upper valve, lower valve, and gauge body, blow off valve, balancing tube and lamp house. The upper valve and lower valve can be fully opened and closed by Hand. Inside the valve body. There is a safety steel ball and safety valve seat. When the quartz glass rube is broken suddenly, the steel ball will remove to the safety valve seat in high speed pushed by high pressure steam to shut off the channel of the gauge automatically until the upper and lower valves is closed by hand. The ball will be reset by the pressure from the balancing tube and by its gravity.
