Description of High Precision high frequency Radar Water Level
Sensor Water Level Transmitter
The intelligent radar level gauge transmits and receives very short
microwaves with very low power through the antenna system. Radar
waves travel at the speed of light. The operating time can be
converted into a level signal by means of electronic components. A
special time extension method ensures stable and precise
measurements in a very short period of time. Even in the presence
of false reflections, the level echoes can be accurately analyzed
by our microprocessor technology and software. By entering the
container size, the overhead distance value can be converted into a
signal proportional to the level. The instrument can be debugged in
empty warehouse. Applications in solids measurement can use K-band
high-frequency sensors. Due to the excellent focusing of the
signal, neither installations in the silo nor adhesions on the silo
walls will affect the measurement.

Application of High Precision high frequency Radar Water Level
Sensor Water Level Transmitter
It is used for non-contact continuous measurement of the level of
liquids, slurries and granular materials. It adopts the measurement
method of microwave pulse (PTOF) and can work normally in the
industrial frequency band. The beam energy is low and can be
installed in various metal and non-metal containers or pipes,
without harm to the human body and the environment.
