This project provides a summary of test data based on the flow disturbance tests that are outlined in Annex B of the International Organization of Legal Metrology (OIML) R 137-1. The data that are included in this report are for multipath gas…
SICK FLOWSIC500 (FS500) ultrasonic flow meters were tested over a range of pressures and flow rates in piping configurations that are similar to those commonly used for rotary meters. This project extends the results previously reported in…
The influence of upstream pipe roughness on the performance of multipath ultrasonic flow meters was examined through a set of experiments involving three different brands of ultrasonic flow meters. Tests were conducted with 16-inch meters with…
Evaluates the effect of flow conditioner location on the performance of a Daniel Industries 8-inch Senior Sonic ultrasonic meter with enhanced electronics and improved transducers. The meter was tested in high pressure (5500 to 5800 kPa) natural gas…
Flow performance evaluation of an 8-inch SICK MAIHAK FLOWSIC600 4+1 and Check ultrasonic meter assembly. Tested in high pressure (5500 to 6000 kPA) natural gas with pipe Reynolds numbers between 2.2E6 and 11E6 and tested in baseline, two elbows out…
The influence of upstream pipe roughness on the performance of multipath ultrasonic flow meters was examined through a cursory literature review and an examination of experimental test data supplied by the natural gas industry. The results of these…
This project provides a review of previously completed PRCI projects on the topic of the effects of upstream disturbances on ultrasonic meter performance. This compendium document includes brief summaries of the projects along with comparisons of the…
This project evaluated the effect of six different designs of end-fed header configurations on the velocity profile in an American Gas Association Report No. 9 (AGA-9) default ultrasonic flow meter run. The header configurations were experimentally…
Protocols have been developed to ensure complete and consistent collection of PRCI USM calibration data, logs files and documentation of test piping layout. The protocols also describe how to organize the data for inclusion in the PRCI USM test…
SICK Flowsic500 ultrasonic flow meters were tested over a range of pressures and flow rates in piping configurations that are similar to those commonly used for rotary meters.
