Radar Level Meter can measure the level of a wide range of liquid or granular products on a large variety of installations, including LPG and LNG. The level meter does not require calibration or commissioning when installed and can be applied in agitated process conditions and agitated vessels.
Based on radar signal, the radar level meter transmits a high frequency signal which increases linearly during the measurement phase. The signal is emitted, reflected on the measuring surface and received with a time delay, t . For further signal processing, the difference is calculated from the actual transmission frequency and the received frequency and is directly proportional to the distance.
