26G Dual-beam Radar Level Gauge, PTFE Barrel For Corrosion Resistance

A dual-beam radar level gauge is an instrument that measures liquid level by utilizing the reflection characteristics of radar waves.

The dual-beam radar level gauge operates based on the time-of-flight principle. It emits extremely short microwave pulses with very low energy. These pulses are transmitted through the antenna system and travel along the cable or rod probe. When the pulse encounters the material surface, it is reflected back and received by the receiver within the instrument. The electronic components calculate the distance between the material surface and the probe based on the pulse travel time, and then determine the liquid level height.

• High measurement accuracy: For instance, the True Echo PRS dual-frequency pulse radar level gauge from APG Company can achieve a measurement accuracy of ±0.25% of the measured range.
• Strong anti-interference ability: The dual-frequency band technology ensures accurate and reliable liquid level measurement, and it can operate normally even in harsh environments with foam, steam or turbulence.
• Strong adaptability: It can be used in extreme temperature, pressure and other environments, and can measure various liquids, including corrosive, viscous and foamy liquids.
• Easy installation and maintenance: It does not involve complex pipelines or moving parts, making it easy to install and maintain.

Dual-beam radar level gauges are widely used in industries such as oil and gas, chemical, food and beverage, pharmaceutical, water and wastewater treatment, and can be used to measure the liquid level in storage tanks, reactors, containers and pipelines.
