Differential Pressure (Flow)
VEGADIF
-
In flow-rate measurement via differential pressure measurement, the differential pressure is measured with the help of a differential pressure device, e.g. an orifice plate or a dynamic pressure probe (pitot tube). The differential pressure transducer calculates the flow rate from the measured value provided by differential pressure system. Thanks to the finely graduated ranges of the measuring cells and the minimal measurement deviation, very accurate flow-rate measurement can be realized.
