This is a book about flow measurement and flowmeters written for all in the industry who specify and apply, design and manufacture, research and develop, maintain and calibrate flowmeters. It provides a source of information on the published research, design, and performance of flowmeters as well as on the claims of flowmeter manufacturers. It will be of use to engineers, particularly mechanical and process engineers, and also to instrument companies' marketing, manufacturing, and management personnel as they seek to identify future products.

I have concentrated on the process, mechanical, and fluid engineering aspects and have given only as much of the electrical engineering details as are necessary for a proper understanding of how and why the meters work. I am not an electrical engineer and so have not attempted detailed explanations of modern electrical signal processing. I am also aware of the speed with which developments in signal processing would render any descriptions which I might give out of date.

In the bibliography, other books dealing with flow measurement are listed, and my intention is not to retread ground covered by them, more than is necessary and unavoidable, but to bring together complementary information. I also make the assumption that the flowmeter engineer will automatically turn to the appropriate standard; therefore, I have tried to avoid reproducing information that should be obtained from those excellent documents. I include a brief list that categorizes a few of the standards according to meter or application.
