Measuring element with strain gauge measurement bridge for volumetric flow measurement in homogeneous liquids and gases

摘要

The flow sensor (1) has a bending element (3), deflected from an original position, based on a force reaction, which is due to the flow of a liquid and a gaseous medium, to produce a signal depending on the amount of deformation. The bending element is connected in the flowing medium in either circularly or at two opposite lying places at least, rigidly with its frame (9) or the tube wall. A resistance of a strain gauge strip measurement bridge (7) is arranged on the surface of the bending element (3), at the place of maximum voltage and then at the place of the min. voltage of the bending element.
