PROBLEM TO BE SOLVED: To provide a level gauge capable of detecting a level position in the non-contact state to a medium to be measured. SOLUTION: Level positions L1, L2 are L3 synchronously measured and calculated through a signal processing unit 13 and level position measuring circuits CL1-CL3 by a plurality of transmitting and receiving sets A, B and C, respectively, are averaged, and the result is displayed on a display part 18. |
