In-House Engineering

All Amity Venturi Meters are designed using the Amity Computation Module within The Flow Consultant™ software. This module was developed by R.W. Miller exclusively for Amity Flow.

Our program uses customer specific line conditions, such as temperature, pressure, and fluid properties, to design the most accurate meter in their flowing conditions, line size, and materials. Every venturi tube design is specific for the customer application. The program is based on scaled equations with pre installed fluid and material properties providing repeatability.

History of Amity's Venturi Meters

We control the entire fabrication process from start to finish which allows for repeatability: our flow meter designs match our products. Our products are built to such tight tolerances, we can consistently surpass both ASME and individual design standards for results between .25% to .5%. In 2008, we formed a partnership with R.W. Miller PhD, PE, the leading industry flow engineer, to design the most efficient Venturi meters and continually push the model to create new and improved products. We have manufactured and sold Venturi tubes since 1973 under other labels, and we are in the unique position of supplying our Venturi flow meters directly to our customers.
