Glass tube level gauge Direct-reading liquid level indicator 

We are one of the repute's manufactures in China, we produce the level gauges and flow meters. Our products are Magnetic level gauges, glass tubular level gauges, glass sheet level gauges(transparent type and reflective type, sight glass level gauges), drop-in type level gauges, capacitive level gauges, level indicator, level transmitter and sensor. Flow meters: Metal rotary flow meters, vortex flow meters and turbine flow meters, electromagnetic flow meters, oval gear wheel flow meters, precession vortex flow meters and roots flow meters.


B43H-64 Quartz tubular glass water level indicator
This B43H-64 Tube type Water Gauge are composed by top valve (steam valve) bottom valve (water valve), gage body, Drain valve, balance pipe etc.
Top valve and bottom valve is a quickly composed valve, not only manually open quickly and all closing, as there are insurance valve and a insurance bead in valve inside, when the quartz tube suddenly blow up, insurance steel bead will quickly apical under the high pressure pop, then close the up and down passageway automatically, until Manual closing fast valve, Insurance bead will get pressure balance by balance pipe, has obtained by insurance bead self-respect, so will not appear False water and other no good phenomena.
 
1.  Operating pressure: 1.6-10MPa
3.  Length: 440-670mm
4.  medium temperature:≤450 ºC
5.  Material: Q235-A carbon steel

One Structure and working principle
Flanges are added to meter with up and low valves. The flanges connect with tank and make a communicator with tank. Then the liquid level will be read from the Transparent glass tube or glass plate directly.

The upper and lower valves have steel ball inside. So if the glass plate or glass tube was broken by accident, the steel ball will block the channel under pressure, and to assure the container be sealed automatically which can prevent the liquid flowing out.

There is screw fixed on the valve ends. When sampling or repairing the meter, rotate the screw and dismounting the meter.
