voomõõtur, mille mõõteava sulgemiseks kasutatav jõud tekitatakse gravitatsiooni asemel vedru abil, nii et voomõõturit saab paigaldada horisontaalselt
flowmeter in which the force tending to close the orifice is provided by a spring instead of a gravity, so that the flowmeter can be installed with its axis horizontal
In some models of the spring-loaded variable-head meter the displacement of the plug provides the readout, and in others the readout is the differential pressure.
