Extending Flow Measurement Capacity with the Straighttube Coriolis Technology
Tao Wang, Yousif Hussain
Abstract:
Coriolis flowmeters had been mainly developed and used in line sizes less than DN100 (or 4-inch) because the size of the flow sensor itself could become too unwieldy and expensive for practical uses. This paper specifically reports the latest research and development of using the straight-tube Coriolis technology to extend flow measurement capacity to a high flow range. Design of the Coriolis flow sensor using a straight-tube configuration is firstly presented. Then, description of a special calibration procedure used in the manufacturer’s gravimetric water flow rig is provided. Finally, an extensive test programme within internal facilities and other independent facilities is also reported. Test results verified straight-tube flowmeters’ performance and showed a step forward in advancing the general Coriolis flowmetering technology.
