ABSTRACT:
A radar level gauging system for determining a level of a surface of a product in a tank, comprising a propagation device arranged to allow microwave signals to propagate towards the surface, and to return a reflection of the microwave signals from the surface and at least two radar level gauge (RLG) units. Each RLG unit includes transceiver circuitry, processing circuitry connected to the transceiver circuitry and adapted to determine the level based on a relation between transmitted and received signals, and a communication interface. The system further comprises a communication link interconnecting the RLG units, for communicating control data between the RLG units, the communication link comprising an isolating interface, ensuring galvanic isolation between the RLG units. One unit may communicate configuration data to the other RLG units which results in a simplified configuration of the sensor system and thus more cost effective compared to the prior art solutions.
