摘要： Method and apparatus for determination of the density of a treatment liquidor a pair of pressure sensors vertically spaces (10) are arranged in terms of measuringthe pressure of the processing liquid and are connected to a common device for
measuring the or differential pressure transducer (13) via pressure transmission conduits(12). The temperature of the transducer and possibly adjacent parts of the transmissionpaths of the pressure is thermostatically controlled and maintained substantiallyconstant, while the parts (17) of the conduits (12) adjacent to the pressure sensors (10)take the liquid temperature treatment. The intermediate pieces (16) ducts are disposedsymmetrically about a horizontal line and preferably are arranged in a horizontalcommon plane so as to avoid measurement errors.
