1. 1.Description of water 1.8GHz guided wave radar level transmitter meter

Guided wave radar transmitter works on the principle of time and travel (TDR). Radar wave travels at the velocity of light. The flying time is converted into level signal via the electronic components. The probe emits high frequency wave pulse which travels along a cable probe or a rod probe. When the wave pulse reaches the medium surface, it will be reflected and received by the receiver, and then the distance signal will be converted into level signals.

The reflected wave pulse travels back along the cable and arrives at the electronic unit. The microprocessor will process the signals and recognize the returned waves from medium surface. The identification of correct return wave signals can be done by the intelligent software.

The water radar level meter can be used to measure the liquid or solid powder.
