to choose the measurement methods of microwave pulse radar thermometer, low beam energy, will not damage the body and the environment, and can be within the scope of industrial frequency band normal operation, the device for pipeline, all sorts of metal and nonmetal container, about in inert gas and evaporation, pressure, temperature change larger occasions can be run, the non touch measurement methods of particle material, pulp and liquid can be successively measurement, is a launch microwave antenna to the measured medium level, a new liquid level measurement of appearance, strong function is higher after the antenna to launch energy measured medium low very short microwave pulse signals and acceptance of the reflected signal, and then measure the transmission and reflection of the time or frequency difference, and then complete the discriminant out container practical liquid level value intentions, the radar thermometer features five displacement, no driving part, not touch measurement, not affected by temperature, pressure, steam and dust aerosol and constraints, is suitable for the viscosity of the medium, poisonous, corrosive medium or non-toxic cleaning medium level measurement.

because radar liquid level measurement principle of juice and the microwave relay characteristics, so the relative dielectric constant and dielectric fluid turbulent and bubbles of the tested materials such as characteristics of the microwave signal attenuation formation, serious and even can't work. So different material has different relative dielectric constant. Because of too small relative dielectric constant to form useful signal of microwave attenuation, so each radar thermometer has a minimum relative dielectric constant, the user selects the radar time temperature. First to think about the relative dielectric constant of the material to make the radar thermometer for normal operation.
