Venturi Meter Engineering
Amity Flow brings over four decades of experience to every venturi meter project. We manage every step of the process to deliver the most accurate, durable and repeatable products to our clients. Our engineering team starts the process with the Amity Computation Module of The Flow Consultant™. This software was developed in collaboration with R. W. Miller exclusively for Amity Flow.
A comprehensive engineering solution
Size and Compute dimensions in the same software
Specialized designs to fit application can be designed based on fluid mechanics a CFD (computational fluid dynamics)
Develop and check AMITY module equations using Math Cad and CFD AMITY program
Compute all dimensions based on pressure and temperature corrections presented in Miller Flow Measurement Engineering Handbook (GENERIC SOLUTION pg 9.107-9.117 3rd Edition)
Develop the AMITY software module to accommodate other meter designs such as the Wedge meter, Eccentric Venturies, etc.
Offers the ability to set the length of the meter to installation requirements
Easily and timely add user inputs and requirements to module.
Continually update discharge coefficient equations based on newly obtained laboratory data.
Amity Computation Module
The Amity Computation Module computes pressure and temperature factors in accordance with ASME, ISO standards and the equations detailed in the Flow Measurement Engineering Handbook by R.W. Miller. This module is forward compatible and will accommodate future changes in calibration and standards. In addition to the creation of our standard production, this module allows Amity Flow to efficiently design solutions for specific customer requirements
Yields Better Products
The result of the work with Dr. Miller and the Amity Computation Module is the first new proven Venturi Meter designs in 30 years.
The S-Design has a cylindrical radius inlet geometry. The entrance to the PTC-6 throat section is critical to insure boundary layer development length is in accordance with the PTC-6 theoretical extrapolation requirement. AMITY S-design use an inlet geometry of the Standardized Torodial Throat Nozzle, extensive data and CFD studies show excellent entrance to the throat results for this geometry.
The T-Design Amity PTC-6 flow meter, uses a Halmi double cone entrance with a unique cone angles and a throat entrance developed based on test results in Holland (Miller 1989), with confirming CFD studies.
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.
