The classical Venturi tube lends itself for highly accurate flow measuring. lts special design implies its use in cases where pressure loss is to be kept low. lt is, for instance, applied in the field of flue-gas flow measurement. The differential pressure is read by means of several pressure tappings inserted in the tube‘s circumference in regular distances.

The Venturi Nozzle is ideally suited to applications where large pressure losses should be avoided. In contrast to the classical Venturi Tube this device uses the same upstream pipe lengths as Orifice Plates. The average error amounts to about 1.3% of maximum flow.

Features

Classical Venturi tubes are available in nearly all DN, and, depending on the respective diameter, up to PN 400. The overall length has, as a principle, to be computed. As a rough rule for the overall length, however, applies the formula 5 x D.

Applications
