products description

This cutting-edge tool combines advanced radar technology with the principle of guided wave propagation to provide an accurate and non-intrusive method of measuring the level of liquids and solids in a variety of vessels and pipelines. Whether you work in the chemical, food, pharmaceutical or waste management industries, radar level gauges will revolutionize the way you manage materials.

So how does the radar level gauge work? It all starts with high-frequency microwave pulses emitted by the device and guided along a detection component, which can be a steel cable or rod, depending on your specific needs. As the pulse propagates toward the medium under test, it encounters any changes in the surrounding dielectric constant and some of the pulse energy is reflected back.

By measuring the time interval between the transmitted pulse and the reflected pulse, the radar level gauge can accurately determine the distance of the measured medium and provide you with a real-time level reading. This information can be displayed on a digital screen, transmitted wirelessly to your computer or smartphone, or integrated with your existing control system for process automation.

But the advantages of radar level gauges don't stop there! Unlike other liquid level measurement methods such as ultrasonic or capacitive sensors, radar level gauges are not affected by changes in temperature, pressure or material composition. It can even detect the level of frothy or turbulent liquids that are difficult to measure with other devices. And because it uses non-contact technology, the risk of contamination or damage to the measuring equipment is greatly reduced.

Investing in radar level gauges means investing in your productivity, safety and profitability. With its high precision, low maintenance and versatility, you'll wonder how you ever managed without it. Contact us today to learn more about how radar level gauges can transform your operations!
