Low-frequency wave radar level gauge is a type of radar level measurement instrument with a working frequency typically around 6 GHz (such as 6.3 GHz). It measures the liquid level by transmitting and receiving microwave pulses. With its outstanding penetration ability and strong adaptability to harsh working conditions, it has become the preferred solution for reliable measurement in complex industrial environments.

• Wide beam angle: The lower the frequency, the wider the beam divergence angle, and the wider the coverage range.
• Large antenna size: With the same antenna, the beam of low frequency is wider than that of high frequency.
• Strong resistance to dust and material curtains: The longer the wavelength, the better the penetration, making it suitable for environments with high dust levels and granular materials.

• Petrochemical: It is used for measuring storage tanks of crude oil, refined oil, asphalt, liquefied gas, etc., especially suitable for occasions with steam, foam or volatile gases.
• Power and Energy: It is used for liquid level measurement in boiler steam drums, deaerators, water tanks, etc., and can handle high-temperature, high-pressure and steam environments.
• Water Treatment and Environmental Protection: It is used for liquid level measurement in sewage treatment tanks, sludge storage tanks, dosing tanks, etc., and can penetrate foam and suspended matter for measurement.
• Food and Pharmaceutical: It is suitable for various storage tanks with hygiene requirements, and can measure liquid medicine, syrup, alcohol, etc., without pollution and easy to clean.
• Metallurgy and Building Materials: It is used for solid material level measurement in mineral powder storage tanks, cement storage tanks, coal powder storage tanks, etc., and can penetrate dust, with good adaptability to inclined surfaces.

If you are dealing with a "dirty, messy and poor" environment, such as a solid silo with high dust, a sewage pool with thick foam, or a chemical reaction tank filled with steam, then low-frequency radar should be your first choice.
