液位計。[Scope of Claim for Utility Model Registration] 1. An immersion type that has a pressure detection part that is inserted into the liquid to be measured and detects the head pressure of the liquid, and that detects the liquid level of the liquid to be measured from the pressure detected by the pressure detection part. In the liquid level meter, the output characteristic value data of the pressure detection section in the liquid level measurement range is built-in, and the pressure is calculated by comparing and calculating the actual liquid head pressure value to be measured and the output characteristic value data. An immersion type liquid level meter characterized by eliminating linearity errors in the detection section. 2. The immersion type liquid level meter according to claim 1, wherein a non-volatile memory is employed as the means for storing the output characteristic value data.
