HVT-HALMI VENTURI FLOW METERS

HVT-CI Halmi Cast Iron Venturi Meters
begin their journey to the customer.

The HVT-Halmi Venturi Flow Element design, developed and perfected by Dezsoe Halmi, founder of Primary Flow Signal, Inc., is a proprietary design offered exclusively by the company for high accuracy and high reliability flow measurement of pressurized line fluids including liquids, gasses, and steam.  

In its embodiment as the HVT-SM Sealed Metering System, this revolutionary design accommodates flow measurement of high viscosity line fluids, solids bearing line fluids as well as harsh and/or contaminated line fluids.

This design is also available in the rectangular configuration for conduits shaped  thusly.

This design is available in a variety of configurations, including cast iron pressure vessel, fabricated (welded) metal pressure vessel,  plastic insert style, welded insert style, and welded-in pressure vessel style.  Additionally, the HVT is offered as a cast in place (usually concrete and typically rectangular) configuration.  PFS, Inc.  Applications specialists can help you select from the wide range of standard product configurations that we have available, or our engineers can custom tailor a solution for your specific and unique application requirements.

This basic design has numerous embodiments that are each intended for certain very specific application conditions.  To access more information on the HVT-Halmi Venturi Meter, please view the following subjects, or CONTACT us.
