差圧が差圧検出器１によって測定される。2. Description of the Related Art A conventional example will be described with reference to FIG. 8, which is a sectional view thereof. This conventional example mainly measures the water level in the tank based on the pressure at its bottom. That is, one pressure is the pressure at the bottom of the tank and the other pressure is atmospheric pressure, and the water level in the tank is determined from the difference between these pressures, that is, the differential pressure. In FIG. 8, covers 3.4 are removed on the left and right sides of the main portion of the differential pressure detector 1 via O-rings 2, respectively. The left cover 3, the connecting pipe 60, and the base 6 are integrally welded, and the flange 5 and the seal diaphragm 7 are connected to the base 6 with a gun or screws. The recessed space of the base 6 in contact with the seal pulley A/flamm 7, the hollow part of the connecting pipe 60, and the internal space of the cover 3 on the left end side of the main part of the differential pressure detector 1 are filled with a pressure transmission medium. Filled liquid 8 is filled. The flange 5 is used to attach the entire device to the bottom outer wall of a tank (not shown). One pressure, for example the pressure based on the level of the stored liquid at the bottom of the tank, acts on the outer surface of the sealing diaphragm 7,
It is transmitted to the left end surface of the main part of the differential pressure detector 1 via the sealed liquid 8. The other pressure, for example atmospheric pressure, is placed on the right cover 4.
It is introduced from the pressure guiding hole and directly acts on the right end surface of the main part of the differential pressure detector 1. The difference between the one pressure and the other pressure, that is, the differential pressure is measured by the differential pressure detector 1.

When the fluid in contact with the outer surface of the seal diaphragm 8 is at a high temperature, not only the flange 5 and the base 6 but also the sealed liquid 8 become high temperature, and as a result, the differential pressure detector 1 is also heated to a high temperature. If the differential pressure detector 1 becomes hot, not only will it not be able to properly detect the differential pressure, but in extreme cases it may even be destroyed. An object of the present invention is to provide a flanged differential pressure measuring device that solves the above-mentioned problems of the prior art and is capable of measuring even when the fluid related to one pressure of the differential pressure is at a high temperature.
