Radar Level Transmitter Non Contact Type Radar Level Transmitter With Remote Indicator Guided Wave Radar Level Sensor
Radar level sensors are usually housed in an assembly that combines the transmitter and receiver antenna in one device.
The two main radar level sensors in use are Air-to-Air Radar (TAR) and Guided Wave Radar (GWR).
Airborne radar level sensors are the most common type as they are non-contact and easier to install. The emitted magnetic waves fan out from the sensor until they hit the liquid surface and are reflected back. The main disadvantage of the TAR level sensor is that the electromagnetic pulse energy is attenuated by the longer distance and the lower dielectric process medium. TAR level measurement technology can be used in aggressive chemical applications as it does not come into contact with the fluid being measured.
Guided wave radar types include a waveguide mounted in front of the sensor to focus microwave pulses and boost the reflected wave energy. This allows the use of GWR-type sensors with lower dielectric process media that would otherwise degrade the performance of TAR-type sensors.
Radar level sensors are mounted above the liquid level on the top of the tank, or on a platform that spans the top of the open tank.

● Low Temperature
We can withstand the extreme process temperature in cold environment, and the robust sensor can still obtain stable and reliable measurement results even below freezing point without freezing or condensation.
● High Temperature
We are not afraid of high temperature and direct sunlight or extremely high medium and ambient temperature, such as blast furnace used in mining and petrochemical industry, which can be perfectly adapted.
● Humidity
Our instruments are not afraid of humidity, waterproof, and can be kept dry under various conditions. They can be used in water and wastewater treatment and food industries.
