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…
The objectives of this research are to develop methods for performing ultrasonic flow meter (USM) diagnostic evaluation automatically and a software tool with all necessary attachments.
USM-based diagnostics have been established and thirteen…
This project provided an updated literature review and market review for clamp-on ultrasonic flow meters for oil and gas applications. In addition, this project included updating a guidelines document that was previously developed by PRCI for…
The response of gas flow meters to different gases and the accompanied potential uncertainty increase is an important subject in industry. Multiple measurement technologies exist and are expected to behave differently under the change of gas type and…
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…
There were two objectives for the program described in this Final Report: 1) to develop and test a portable system to measure flow (and horsepower) in an operating centrifugal natural gas compressor, and 2) to understand and reduce the possible…
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…
This project provided a proof of concept for an in-situ verification method for ultrasonic flow meters in natural gas service. The tested method consisted of simultaneously injecting helium in a minimum of two locations upstream from an ultrasonic…
There are two methods broadly used for sediments and water (S&W) content determination, centrifuge method, and the Karl Fischer titration. They consume a significant quantity of toxic hazardous solvents such as Toluene, o-xylene, and chloroform.…
Measurement of the throughput of a natural gas compressor can be undertaken using a constant flow tracer dilution technique. In this technique, a constant flow of tracer is introduced into the piping upstream of the compressor while samples of…
