A new Guidance Note on Coriolis meters has just been placed on-line to offer advice on this important metering technology.
“This will be useful for anyone with an interest in Coriolis meters, including end users,” says Flow Measurement Engineer, Chris Mills, who put the information together. “It provides information on the operation and calibration of this type of meter. It also highlights the key areas that people should be aware of to ensure optimal use and performance.”
The guidance covers a wide range of issues relating to Coriolis meters, including meter installation and zeroing, alongside advice on service conditions and the status of current research. It is a key document, given the importance of this type of metering technology, which can be utilised for nearly all applications, and which has a growing market share in many different industries such as oil & gas, food & beverage, chemicals and pharmaceuticals.
“This guidance is a living document and will be updated as we continue to do our research and push forward the boundaries of knowledge in this area,” says Chris. “It was produced as part of our role as a leading National Measurement Institute, and underlines our commitment to ensuring good measurement practice.”
As one example of the type of advice provided, the Guidance Note explains that, while most Coriolis manufacturers claim that their Coriolis flow meters are not adversely affected by installation effects, a minimum of 5 diameters of straight pipe should be installed upstream and downstream of such a device. This minimises any potential stress on the device and allows for the meter to be clamped securely.
The guidance builds on the research and knowledge transfer work that has been done on the importance of calibrating Coriolis meters at operating conditions. This is a vital issue, as elevated temperatures, pressures and viscosities have significant effects on the performance of this type of meter.
