The ISO 5167 Compliant Design Venturi – A Further Summary of Calibration Experience

Kegel, T. M.

Abstract

This is the second paper describing a program to organize and analyze the results of a large number of venturi meters calibrated using compressed air. Part four of the ISO 5167 standard specifies discharge coefficient values. The calibration results are organized into four categories based on a qualitative judgment as to how well the calibration fits the ISO coefficients. The database contained 59 venturies when the first paper was published; the current summary is based on 76 calibrations.
