The Guided Wave Radar Level Transmitter is an instrument for measuring the level of solids and liquids commonly used in industry. It transmits electromagnetic pulses with the steel wire cable or tube/rod to propagate at the speed of light; when these encounter the surface of the medium to be measured, the pulses are partially reflected to form an echo wave and returned to the pulse transmission device along the same path, and the liquid level height can be calculated. It uses advanced echo wave processing technology with a wide range of applications, capable of measuring the low dielectric constant of the solid buck. and capable of measuring the solid level, liquid level and average surface area. Product models include coaxial cable, tube/rod, steel wire type at customer's choice, suitable for liquid level measurement in high temperature and high pressure fluid.
