A NEW FLOW CONDITIONER FOR 4-PATH ULTRASONIC FLOWMETERS

G J Brown, B W Griffith

Abstract

There are benefits, limitations and trade-offs to be taken in to account when considering using a flow conditioner with an ultrasonic meter. These include aspects such as the pressure loss, the risk of fouling and the influence on meter repeatability, as well as the ease and reproducibility of manufacturing. This paper discusses different flow conditioner designs and introduces a new design intended for use with 4-path ultrasonic flowmeters. Performance data and permanent pressure loss measurements are presented and compared with a commonly used form of perforated plate flow conditioner. It is shown that comparable flowmeter performance can be achieved while reducing the pressure loss significantly.
