VENTURI TUBES

VENTURI TUBES

Techno-Flow has designed its Classical Style Venturi Tubes to meet each customer's specific flow measurement needs with engineering that covers a wide range of applications. These maintenance-free tubes offer a constant degree of accuracy, a low susceptibility to erosion, high pressure recovery, and they can be installed at any angle from horizontal to vertical.
Techno-Flow manufactures venturi tubes in sizes ranging from 4" to 48" and larger. Customers can specify tubes for high and low pressures, volumes, and temperatures. Construction materials include carbon, alloy, and stainless steels. Techno-Flow can supply other materials on request for special applications.
Throughout the manufacturing process, skilled machinists and welders proceed according to A.S.M.E.-approved procedure specifications with supporting procedure qualification records. Techno-Flow has A.S.M.E. authorization to use "PP" (Power Piping) and "U" (Pressure Vessel) code symbols. Stringent inspection procedures assure conformity to code or customer specifications.

Techno-Flow manufactures venturi tubes to an accuracy of ± 1.5% uncalibrated and ± .25% for a calibrated venturi tube and pipe section. Accuracy is contingent on proper installation and on beta Reynolds, Number limitation.

VERSATILITY

Can be used in air, water, vapor, steam, gas, chemical, sludge and slurry applications.
Available in carbon, alloy and stainless steels as well as other materials, based on request and design suitability.

ECONOMY

Short upstream piping required.
No moving parts, simple configuration, maintenance-free.
Lower susceptibility to erosion than the square-edge orifice plate.
Lighter than cast type; fabricated from plate, pipe and bar stock.
Lower shipping costs.
Lower installation costs.

EFFICIENCY

High pressure recovery.
Sustained accuracy.
Wide range ability - will operate down to 200,000 pipe Reynolds number. Techno-Flow recommends laboratory flow calibrations below_200/)00 pipe Reynolds number.
High repeatability due to simple configurations and no moving parts. Accuracy is contingent on proper installation and on beta Reynolds Number limitation.
