Proving Liquid Ultrasonic Flow Meters for Custody Transfer Measurement
ثبت نشده
چکیده
Liquid ultrasonic flow meters (LUFMs) continue to gain popularity in petroleum measurement with the promise of high accuracy and low maintenance. These are favorable features, but because of the high volume and value of petroleum products, buyers and sellers must have a high level of confidence in the accuracy of measurement. This assurance in custody transfer measurement is gained by adherence to the standards, procedures and methods that define the measurement process.

متن کاملA simple and novel method for acoustic streaming power measurement of ultrasonic horn
Ultrasonic horn with transfer of acoustic wave into an aqueous solution results in unique properties. When, transfer of sound wave into a liquid results in liquid movement in the direction of wave propagation which gradually loses its energy due to the viscous friction. This wave motion induces a flow which is known as acoustic streaming or micro-streaming. In this article, a simple innovative ...
متن کاملA Comparison of Liquid Petroleum Meters for Custody Transfer Measurement
Petroleum products bought and sold on the world wide market may be transported over thousands of miles and change ownership many times from the well head to the end user. Each time the product changes ownership, a “custody transfer” is completed and both buyer and seller expect their asset share to be accurately measured. The dynamic measurement provided by meters is a convenient and accurate m...
متن کاملThe Performance of a Multi-path Ultrasonic Meter with Wet Gas
Due to increasing economic pressures in natural gas production, there is a recognized demand for flow meters that are able to measure when a significant quantity of liquid is present in gas flows. The key issues are that the liquid quantity is often unknown and its presence can affect the operation of traditional dry gas meters making the gas flow readings inaccurate. A number of techniques are...
