is the same as with a standard orifice meter. It works with both clean or dirty gases and liquids, generally 4 in. and larger line sizes; accuracy is ±2%. Volumetric flowmeters whose output is not proportional to the square root function are termed linear flowmeters. Meters are either linear due

determines flow by measuring fluid pressure before and after an orifice in the flowmeter. The size of the orifice is determined by the application flow rate and fluid type. As described in Bernoulli's principle, fluid flow passing through an orifice increases in velocity, causing an increase in kinetic

on the other side. The material is conditioned to a constant temperature, within a tenth of a degree, in order to maintain a constant viscosity. Desired flow is achieved using a variable pressure and specific orifice size. On an automotive enclosure, for example a hood, the dispenser robot moves across
