Summary
INITIAL CONSIDERATIONS
Some years ago at Cranfield, where we had set up a flow rig for testing the effect of upstream pipe fittings on certain flowmeters, a group of senior Frenchmen were being shown around and visited this rig. The leader of the French party recalled a similar occasion in France when visiting such a rig. The story goes something like this.
A bucket at the end of a pipe seemed particularly out of keeping with the remaining high tech rig. When someone questioned the bucket's function, it was explained that the bucket was used to measure the flow rate. Not to give the wrong impression in the future, the bucket was exchanged for a shiny new high tech flowmeter. In due course, another party visited the rig and observed the flowmeter with approval. “And how do you calibrate the flowmeter?” one visitor asked. The engineer responsible for the rig then produced the old bucket!
This book sets out to guide those who need to make decisions about whether to use a shiny flowmeter, an old bucket, nothing at all, or a combination of these! It also provides information for those whose business is the design, manufacture, or marketing of flowmeters. I hope it will, therefore, be of value to a wide variety of people, both in industry and in the science base, who range across the whole spectrum from research and development through manufacturing and marketing.
