Abstract

This study examines the traceability and measurement uncertainty of in situ hydraulic calibration using clamp-on ultrasonic flowmeters as a reference. The procedure compares the equipment readings with the reference ones. Measurement uncertainty evaluation uses GUM formulation, considering the linearity conditions of the mathematical models applied. Experimental values are used to test the procedure and its suitability for actual cases where the expected accuracy needs to be achieved.

Keywords

Flow measurement, clamp-on ultrasonic flowmeter, measurement uncertainty, traceability, measurement accuracy.
