ABSTRACT:
The invention is directed to an improvement for a fluid-volume apparatus for measuring a fluid under pressure. A measuring chamber housing with a movable measuring part is arranged in a pressure-resistant outer housing. A fluid medium is present in the space between the outer housing and the measuring-chamber housing. The improvement includes separating this space between the measuring-chamber housing and the outer housing from the fluid to be measured in a fluid-tight manner and providing a pressure-responsive element for placing the above-mentioned space between housings in pressure-equalizing communication with the liquid to be measured whereby the pressure of the fluid medium in the space between the housings is at a pressure which corresponds to the pressure of the liquid to be measured.
