Patent ID: 11933655
Assignee: ROSEMOUNT TANK RADAR AB
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 5:
6. A radar level gauge system for determining a level of a product in a tank, the radar level gauge system comprising:
a transceiver for generating, transmitting and receiving electromagnetic signals;
a probe arranged to extend towards and into the product from a first probe end coupled to the transceiver to a second probe end, the probe comprising a first probe conductor and a second probe conductor being conductively coupled to each other by a probe termination arrangement at the second probe end;
echo signal forming circuitry connected to the transceiver for forming, based on the reflection signal and a timing relation between the reflection signal and the transmit signal, an echo signal exhibiting an echo signal strength as a function of a propagation parameter indicative of position along the probe; and
level determining circuitry connected to the echo signal forming circuitry for determining the level of the product in the tank based on a propagation parameter value indicative of a first threshold position along the probe for which the echo signal has reached a predetermined threshold signal strength, and an offset indicative of an offset distance along the probe from the first threshold position towards the second probe end.
