Briefly describe

The FM continuous wave radar level gauge applies high-frequency signals that vary linearly during the measurement process. The signal of the radar level gauge is emitted from the antenna, reflected on the measured plane, and the echo is received by the antenna.

The frequency difference between the emission of radar level gauge signals and the reception of echoes is used for further signal processing, and the frequency difference corresponds to the measured distance. A large frequency difference should be applied to a larger measurement distance. passFFTThe frequency difference is converted into a spectral difference, which is then used to calculate the measurement distance. The difference between the level and measurement distance depends on the height of the empty tank.

feature

The FM continuous wave radar level gauge is equipped with two-wire technologyFWCMRadar level gauge,FWCMThe mature non-contact antenna technology of radar level gauge is easy to maintain, replacing switches, ultrasonic measuring equipment and pressure transmitters, with low cable cost, high accuracy and high repeatability.

principle

The FM continuous wave radar level gauge is based on the principle of FM continuous wave（FMCW)Using a linear frequency modulation high-frequency signal, the transmission frequency of the high-frequency signal of the radar level gauge varies with a certain time interval(scanning frequency)linearvIncrease, as the transmission frequency varies with the time of signal propagation and is proportional to the distance from the reflecting object, the height of the object is obtained by the difference between the current transmission frequency and the received reflection frequency.
