Thermal Instrument is the leading Fabricated Venturi Tubes Manufacturer in India providing reliable solutions for accurate pressure measurement to the process industry worldwide.
THERMAL Venturi Tubes serve users with accurate measurement of non-viscous fluids in clean & dirty streams Venturi Tubes are virtually maintenance-free. Venturi tubes are manufactured in strict accordance with ASME MFC-3M, BS- 1042, and IS0-5167 standards. These measurement standards provide users with +-/-1.0% uncertainty of discharge coefficient. For critical measurement applications, wet calibration at reputed flow laboratories can be offered.
A 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. 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 an entrance cylinder of the same diameter as the pipe connected to a conical convergent section, a cylindrical throat, and a conical divergent section which varies in angle from 7° to 15° depending upon the pressure recovery. The high-pressure taps are located in the middle of the inlet section and the low-pressure taps are located at the middle of the throat section. A piezometer ring is sometimes used for differential pressure measurement. This consists of several holes in the plane of the tap locations. Each set of holes is connected together in an annular slot to give an average pressure.
