Patent ID: 11940315
Assignee: ROSEMOUNT TANK RADAR AB
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 5:
6. The filling level determination system according to claim 1, wherein:
the antenna arrangement of the first measurement unit is configured to radiate an electromagnetic second transmit signal generated by the transceiver from the first measurement position towards a second target position on the tank wall spaced apart from the first target position on the tank wall, and for returning an electromagnetic second reflection signal resulting from reflection of the second transmit signal at the second target position back towards the transceiver;
the tank deformation data is additionally indicative of a known relation between the level of the product in the tank and deformation of the tank at the second target position;
the reference data is additionally indicative of a reference distance between the first measurement position and the second target position for a known level of the product in the tank; and
the processing circuitry is configured to determine the filling level additionally based on a timing relation between the second transmit signal and the second reflection signal.
