Description
High pressure recovery and low upstream and downstream requirements
Venturi tubes are reliable, easy to use, and low-maintenance. Venturi tubes are particularly suitable for the measurement of clean liquids and gases.
The main advantages are the higher pressure recovery and the lower upstream and downstream pipe requirements.
At the upstream side, the instrument consists of a gradually decreasing nozzle, through which the medium in a pipe is accelerated. The downstream side is a gradually increasing diffuser section, which enables a high pressure recovery.
Flow measurement with low differential pressures
Due to the fact that a major part of the output pressure is regained, the Venturi tube is particularly suited for measurement in systems with a low pressure differential.
Thanks to the low pressure loss the cost of pumping the medium can be reduced to a minimum.
