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

Claim 11:
12. The method according to claim 9, wherein:
the method further comprises the steps of:
radiating an electromagnetic second transmit signal from a second measurement position towards a second target position on the tank wall, different from the first target position; and
receiving an electromagnetic second reflection signal resulting from reflection of the second transmit signal at the second target position;

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 second measurement position and the second target position for a known level of the product in the tank; and
the filling level is determined additionally based on a timing relation between the second transmit signal and the second reflection signal.
