The patented HVT-Halmi Venturi Flow Element designed, developed, and perfected by Dezsoe Halmi, founder of Primary Flow Signal (PFS), is offered exclusively by the company for the highest accuracy and reliability for flow measurement of pressurized line fluids, including liquids, gasses, and steam, as well as high-viscosity line fluids, solids-bearing line fluids, and harsh or contaminated line fluids.
The HVT-CI Halmi Cast Iron Venturi flow meter is the industry standard for high accuracy and reliable, properly substantiated (2 Sigma), differential producing flow measurement.
The HVT-BCI flow meter is specifically designed to deliver highly accurate, bi-directional measurement. In instances where the same line is utilized for different delivery and/or control functions - like air or gas oxygenation, redistribution of storm sewage, and aquifer storage and recovery-the HVT-BCI provides highly accurate metering for changing system conditions and process objectives.
