Venturi Tubes

Venturi Tubes

Salient features & benefits

• Can be used on slurries and dirty fluids
• Short Upstream piping required
• Low installation costs
• Lower susceptibility to erosion
• Low permanent pressure loss
• Extended product life with no moving parts
• Vertical or horizontal installation

General venturi Tubes serve users with accurate measurement of non viscous fluids in clean & dirty streams. Venturi tubes are virtually maintenance free and corrosion resistant. Venturi tubes are manufactured in strict accordance  with ASME MFC- 3M, BS-1042 and ISO-5167 standards. These maesurement standards provide users with +/-1.0% uncertainty of discharge coefficient. For critical measurement applications, wet calibration at reputed flow laboratories can be offered.

Venturi tube is a low pressure drop metering device. It offers constant accuracy, low susceptibility to erosion, high pressure recovery, and installation at any angle from horizontal to vertical. Corrosion-resistant and virtually maintenance-free, this measurement product performs in a wide variety of applications that include air, water, vapor, steam, gas, chemical substances, sludge and slurry applications.

The classical Venturi tube is made up of a entrance cylinder of the same diameter as the pipe connected to a conical convergent section, a cylindrical throat, and a conical divergent section. The high pressure taps are located in the middle of inlet section and the low pressure taps are located at the middle of the throat section. A piezameter ring is sometimes used for differential pressure measurement. This consists of several holes in the plane of the top locations. Each set of holes is connected together in an annular slot to give an average pressure.
