The technical benefits of radar as a level measurement technique are clear.

Radar provides a non-contact sensor that is virtually unaffected by changes in process temperature, pressure or the gas and vapour composition within a vessel. In addition, the measurement accu- racy is unaffected by changes in densi- ty, conductivity and dielectric constant of the product being measured or by air movement above the product. These benefits have become more significant to the process industry since the advent of low costs, high perfor- mance, two wire loop powered radar level transmitters. This breakthrough, in the summer of 1997, produced an unprecedented boom in the use of non-contact micro- wave radar transmitters for liquid and solids process level application.

‘Radar level measurement – the user ́s guide’ is offered as a reference book for all those interested in the tech- nology, the application, and the prac- tical installation of radar level sen-sors. We cover many practical process level applications rather than the closed niche market of custody transfer mea- surement.

Radar history, physics and techni- ques are presented as well as descripti- ons of types of ra-dar antenna and mechanical and electrical installations.

Now radar is an affordable option for process level measurement. We compare it closely with all of the other process level techniques and give many examples of the myriad applications of radar across all industries. Radar level measurement has come of age. We hope that this book will be invaluable in helping you to see the potential of this latest and almost uni- versal level measurement technology. More than anything, we hope that you enjoy delving into the pages of this book. Peter Devine Technical manager Vega Controls Ltd
