Measuring cell for the continuous determination of a liquid, especially a beverage flowing through a pipe

摘要

A measuring cell for the continuous determination of the carbon dioxide content of a flowing liquid. The cell comprises an inner chamber having a first substantially cylindrical portion, an input conduit for the feeding of liquid to the cell and a discharge line for the removal of the liquid. The input conduit has a portion entering at one end of the first portion tangentially to its peripheral surface and a discharge line has a portion disposed in a direction of the longitudinal axis of the first portion and entering the chamber below the input conduit. The input conduit is constricted at or immediately ahead of the point of entry and a device is disposed within the chamber in the immediate vicinity of the point of entry or directly ahead of the entry of the discharge line for measuring the temperature of the liquid and a second device is disposed at the inner wall of the first portion for measuring the outgassing pressure of the liquid. The two devices produce electrical signals corresponding to the measured values and conductors carry the signals out of the chamber of the measuring cell.
