TDR is sometimes called ‘radar on a rope’ or guided wave radar; its contact-based measurement principle makes it ideal for reliable product monitoring. A probe or cable is lowered into the vessel from the top and continuously measures the product level as it makes contact along its length. This level measurement technology is immune to dust, vacuum, humidity, foam, and variations in pressure, dielectric and temperature. Hycontrol’s VF Series TDR family offers a wide range of gauges and level indicators to meet almost every requirement.
