Displacement Volumetric Meter
Encyclopedia
A Displacement Volumetric Meter is a device which measures total volume. It can operate on the principle of the fluid
sweeping out a fixed calibrated volume, which produces a rotation of a calibrated gauge. By maintaining constant conditions and taking readings over a prescribed period the flow rate can be calculated for the specific operating conditions. The instrument essentially measures total volume.
Some water meters work on the principal to measure fixed volumes of water for billing. These are commonly referred to as "positive displacement meter

Fluid
In physics, a fluid is a substance that continually deforms under an applied shear stress. Fluids are a subset of the phases of matter and include liquids, gases, plasmas and, to some extent, plastic solids....

Positive displacement meter
A positive displacement meter is a type of flow meter that requires the fluid being measured to mechanically displace components in the meter in order for any fluid flow to occur. Positive displacement flowmeters make volumetric flow measurements taking finite increments or volumes of the fluid...
