Information

Radar level gauge is a commonly used liquid level measurement equipment, and the selection of its antenna is crucial to the measurement effect. This article will introduce how to correctly select a radar level gauge antenna to ensure measurement accuracy and stability.

1. Antenna type:

Rod antenna: suitable for general liquid level measurement, with good versatility and stability. Angular antenna: suitable for scenes with liquid buoys or floats, which can better penetrate the liquid surface for measurement. Antenna array: suitable for large storage tanks or complex scenes, capable of providing a wider measurement range and more accurate measurement results.

2. Working frequency:

26GHz frequency band: suitable for general liquid level measurement, with good anti-interference ability and high measurement accuracy. 6GHz frequency band: suitable for scenarios with high dielectric constant or high viscosity liquids, which can better penetrate the medium for measurement.

3. Antenna material:

Stainless steel antenna: corrosion-resistant, high-temperature resistant, suitable for harsh environments such as chemical industry. Polytetrafluoroethylene (PTFE antenna: has good chemical stability and corrosion resistance, and is suitable for food, pharmaceutical and other industries.

4. Antenna installation:

Installation location: The antenna should be installed at the highest point of the measured liquid to ensure accurate signal reception. Antenna angle: The antenna should be at a certain angle to the liquid surface, usually 45 degrees, to ensure that the signal penetrates the liquid surface.
