The relationship between pressure and depth is often exploited in instruments that measure pressure. Two pressure gauges based on this principle are the closedtube manometer and the opentube manometer, which measure pressure by comparing the pressure at one end of the tube with a known pressure at the other end.

Other flowmeters do not measure volume, velocity or mass but rather infer the flow through the flowmeter from other measurements. Differential pressure flowmeters are commonly used to infer the flow rate in a pipe by measuring the differential pressure produced across a restriction. Differential pressure flowmeters such as orifice plate, Venturi, nozzle, variable area, and target flowmeters .
