'''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. | |||
