They are mainly used for power station boiler drums and other water level indications under lowPressure conditions.According to the structure, they are divided into two types: linear and interlaced (blind-zoneless).the light source uses the new LED red and green light sources developed by our compnay,making the water level indication clear and distinct,achieving a good observation effect.It has the advantages of low maintenance, low power consumption, long service life and low cost.

LHSB series Level gauge Is mainly used for liquid level monitoring of boiler drums and various storage vessels in thermal power plants,petrochemical industry and other industrial sectors.It has the advantages of continous water level indication,clear and intutive observation,safe and reliable operation,and convenient installation and operation.It can also be used in conjunction with a television monitoring system to achieve remote video monitoring.

the observation window is made of special Al-Si glass with good optical transmittance and pressure bearing performance.

High-quality mica and compound pad Are selected toEnsure high-Pressure sealing Performance,long-term corrosion resistanceandClear observation.

BotH the steam and water side valves are equipped with safty steel balls,which can automatically close the valevs in case of sudden pressure loss to avoid accidents.

LOw power consumption of light source, long Use time, high brightness, good color purity,Minimal heat dissipation, continuousLy adjustableBrightness, low cost of accessories, and Easy to replace. 

SPecial mechanical structure and processing technology are Adopted to improve the service life of the level gauge.
