Power generation Oil production and refining Water treatment and distribution Gas processing and transmission Chemical and petrochemical industry Special Features Suitable for liquid, gas and steam flow measurement Accuracy ≤ ±0.5 % of actual flow rate Repeatability of measurement 0.1 % Lowest pressure loss in the family of primary flow elements Calibration may be performed if required 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 of a Venturi tube over other differential pressure flow meters 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.
