Flexim ADM 7407 Ultrasonic Flowmeter Evaluation
A Flexim 7407 clamp-on ultrasonic flowmeter (USM) was subjected to a series of tests in order to evaluate its performance under a variety of conditions. The USM was tested under ideal conditions with long undisturbed straight lengths of pipe, both upstream and downstream. In these tests, the USM was set up with the correct fluid properties. The USM was then subject to a series of tests to evaluate its performance under common operational issues. These tests included but were not limited to: power blackouts, power brownouts, random operations, 48 hour running, flow over range and reversal and transient flows.
