ABSTRACT:
According to a level meter of this invention, a pressure corresponding to a fixed water level formed by means of a reference chamber and a vertical pipe is applied to one pressure inlet port of a differential pressure detector, and a pressure corresponding to a water surface or water level inside a container to be measured is applied to the other pressure inlet port of the differential pressure detector by means of a lower pipe. Then, the water level inside the container is measured through the difference between these two pressures, the density of water to generate the pressures to be applied to the differential pressure detector, and the density of steam inside the container and the reference chamber. Adiabatic jackets are attached to the peripheries of the vertical pipe and the lower pipe.
