Instrumentation used with Flowmeters

This is an enormous subject which really needs a book-or, rather, a series of books-to itself, and this chapter must therefore have a very limited aim. This is firstly to deal with a few matters of special importance to flowmeter users, such as the design of piezometer rings and thermometer pockets, secondly to give some idea of the great variety of equipment now available, and thirdly to offer a few practical tips on the use of some of the devices most commonly found in flow metering situations.
