Descriprion High Frequency Radar Level Gauge Radar Water Level
meter Flare
The High Frequency Radar Level Gauge, also known as a Radar Water
Level Meter Flare, is suitable for environments with significant
temperature and pressure variations, as well as the presence of
inert gas, smoke, steam, and volatile substances. It is designed to
operate in hazardous locations and has a robust construction to
withstand corrosive and explosive environments. The 806 radar level
transmitter antenna emits a narrow microwave signal within the
industrial frequency band, with extremely low emission power that
poses no harm to humans or the environment.
The YUNYI-806 radar level transmitter is designed with an
intrinsically safe Ex iaIIC T6 explosion-proof rating, featuring an
aluminum outer casing connected to the earth. It strictly adheres
to national installation regulations for explosion-proof areas.
Moreover, by incorporating components such as air-cooling devices,
water-cooling devices, and purging devices, the working temperature
range can be extended from -40 to 400 degrees Celsius.
Additionally, the pressure sealing components can be adjusted to
extend the pressure range up to 4000 KPa.
