  Principle of liquid level measurement - guidance radar  
     
  High frequency microwave pulses are transmitted along steel cables or steel pipes, reaching the surface of the medium and then emitted back, which are received by electronic components. The transmitter calculates the operating time of the microwave pulse and converts it into the corresponding liquid level or material level output. This transmitter can pre-set the length of the ordered probe without the need for time-consuming adjustments. The steel cable and steel rod can be adjusted to the length suitable for actual needs.
