。 The main body case part has an atmospheric pressure chamber communicating with the atmosphere at one end and a water pressure chamber communicating with the fluid to be measured at the other end, the free end side closed with a bellows lid protrudes into the atmospheric pressure chamber, and the base part extends into the atmospheric pressure chamber. A first bellows fixed to the main body case part, and a second bellows whose free end side closed with another bellows lid protrudes into the water pressure chamber and whose base part is fixed to the main body case part or whose pressure receiving surface is connected to the water pressure chamber. a diaphragm arranged to face the main body and whose peripheral edge is fixed to the main body case portion; a connecting member that connects the bellows cover of the first bellows and the bellows cover of the second bellows or the diaphragm; and the main body. It has a length that is limited to the inner diameter of the case part, and is placed in the main case part with a bending force applied to the free end side via the connecting member and the proximal end fixed to the main case part. and a strain gauge attached to the surface of the strain plate;
A water level gauge characterized in that the pressure of the fluid to be measured applied to the bellows or the diaphragm is converted into an electrical signal by the strain gauge to obtain a signal corresponding to the water level.
