Abstract

PURPOSE: To improve the measuring accuracy by communicating the gap between a diaphragm and a protecting film with the space above the liquid level of a container of a liquid to be measured.
CONSTITUTION: The small gap between a diaphragm 1-1 and a protecting film 30 is communicated through upper and lower grooves 35 and 36 and pipes 37 and 38 with an intermediate tank 33 which in turn is connected through a pipe 12 with the upper space of the tank filled up with a liquid to be measured. Thus, a liquid 31 having a high boiling point such as silicone oil is filled into the continuous space. As a result, even if the pressure in the tank filled with the liquid is lowered to a vacuum condition so that the gases dissolved in the liquid 31 rise as bubbles, the content of the liquid 31 having risen as the bubbles is compensated by the supply of the liquid having no bobble through the pipe 38 so that the measurement can be prevented from becoming impossible as a result of the fact that the film 3 is pulled by the liquid through the bubbles which are generated from the space between the film 3 and the diaphragm 1-1. Thus, the diaphragm 1-1 can be accurately displaced in accordance with the level of the liquid.
