MEASURING EQUIPMENT FOR DETERMINE A RELATIONSHIP BETWEEN AN ENCLOSED GAS VOLUME AND AN ENCLOSED LIQUID VOLUME IN AN ACCUMULATOR TANK

摘要

The present invention embraces a measuring equipment ("M") in order to, within a system (S) distributing liquid and having an accumulator tank ("T") and by means of a control unit (SE) and a calculation unit (D) assigned to the same, allow to determine an instantaneous relationship between an enclosed gas volume (Va) and an enclosed liquid volume "Vb" put under a positive pressure, wherein said accumulator tank ("T") is included in a distribution network ("S") supplying liquid and having a pump (P) and a pressure transducer (R) adapted to become actuated to pump water into the distribution network (S) at a selected low pressure, and adapted to become actuated to stop the action of the pump (P) at a selected high pressure, as well as a pipe system ("S1") to be able to distribute liquid under a selected positive pressure to one or more tapping points (A2, A2a) and wherein said distribution network ("S"), such as next to the accumulator tank (T)1 is provided with a pressure sensor (B) evaluating instantaneous pressure values.
