Venturi Tube

Parsjahd Products - Venturi Tube

Venturi tube is a low-pressure-drop metering device identifiable by its tapered inlet, tapered outlet and straight constricted middle section. Also the venturi tube is the most accurate flow-sensing element when properly calibrated.

Because of being corrosion resistant and ease of inspection, this measuring device performs in a wide variety of application such as air, water, vapor, steam, gas, chemical substances, and sludge and slurry applications.

Venturi tubes are not as reliable at lower Reynolds number as chart below.
