The performance of two 8inch multi-path ultrasonic meters provided by Instromet and Daniel Industries is evaluated in the presence of a 19 tube bundle and the CPACL’ flow conditioner. These flow conditioners are placed downstream of a single elbow and two elbows out of plane. The ultrasonic meters are tested at several locations downstream of the flow conditioners. NOVA’s gravimetric meter prover is used to evaluate the performance of the meters. The present measurements indicate that the use of CPACL flow conditioner results in a near baseline performance of ultrasonic meters.

The two meters were also tested for pulsation effects using some of the solutions suggested by the manufacturers. Present tests indicate that the solutions were not effective enough and the meters are subject to errors when exposed to a pulsating flow.
