Device for the contactless flow measurement of fluids in flexible tubes

摘要

For flow measurement a device with a compact housing and a fixable hinged cover has a measuring channel for inserting a flexible tube such that it becomes deformed in a defined way. The measuring channel extends over the entire width of the housing. A measuring cell arranged in the center of the measuring channel has
four ceramics I, II, III, IV, integrated in a sound-decoupled way and facing each other diagonally in pairs, which are placed in lateral parts on the left and on the right of the measuring cell, and a base plate limiting the measuring cell downwards in the direction of an installation space for an electric evaluation system, wherein the base plate also limits the remaining area of the measuring channel from below.

1. A device for the contactless flow measurement of fluids in flexible tubes, consisting of a compact housing with a fixable hinged cover under which there is, on the upper housing limit, below the hinged cover, a measuring channel with
a rectangular cross-section, wherein the measuring channel extends over the entire width of the housing and is configured for insertion of a flexible, such that the flexible tube is deformed in a defined way in a measuring cell which is arranged in the centre of the measuring channel and wherein: four ceramics I, II, III, IV, are integrated in the device around the centre of the measuring channel in a sound-decoupled way and facing each other diagonally in pairs, which are placed in lateral parts on the left and on the right of the centre of the measuring channel, and a base plate limiting the measuring cell downwards in the direction of an installation space for an electronic evaluation system, wherein the base plate also limits the remaining area of the measuring channel from below, and wherein the base plate is embodied in such way that it can be exchanged according to a modular concept and therefore a change of the geometry of the measuring channel regarding its cross-section from the shape of a square to the shape of a standing rectangle can be carried out.
