The continuous flowmeter

Flow meters are classed as volumetric or inferential, the latter term referring to meters that determine velocity from other variables such as pressure differences across a device such as an orifice plate. There is a large variety of flow measurement device, using numerous physical principles. Full discussion of the whole range of flow measurement device is out of the scope of this book but the reader will find a comprehensive reference in the Flow Measurement Handbook (Baker, 2000). Table 18.4 gives typical information on some of the flow meters usually encountered in the water industry.
