Ideal for Both Gas and Liquid Line Fluids: The adiabatic expansion factor is known and applicable so flow measurement of gas and steam line fluids is fully supported.
No Downstream Installation Effect: Based on decades of lab calibrations, there is no effect on the HVT-Halmi Venturi Meter by downstream disturbers, meaning one can safely close couple valves or other fittings on the downstream end of the meter without any concern for diminished accuracy performance.
Minimal Upstream Installation Effect: The effect of upstream disturbers such as elbows or tees is minimal. Typically, with three (3) to five (5) upstream diameters being provided, there is no error in performance.
Piping Mismatch Minimized Through Technology and Testing: Due to the special geometry of the HVT-Halmi Venturi Meter design, coupled with extensive proprietary research and development, the error introduced as a result of mismatch between piping and meter body that typically occurs in installations, is quantified and well known, and in most cases, has been determined to be minimal.
Shortened Recovery Cones: The HVT recovery cone can be shortened quite considerably without adversely affecting the accuracy of the meter, making it an ideal candidate for replacement projects involving failed ultrasonic meters, mag meters, flow tubes, orifice runs, and many other devices.
