Positive displacement flow meters measure the volume or flow rate of a moving fluid or gas by dividing the media into fixed, metered volumes.

Positive displacement valves are precision dispensing devices designed to provide precise fluid dispensation depending on applications.

Metering pumps are precision pumps, which dispense an exact amount of material.

Liquid flow meters are used for measuring the flow or quantity of a moving fluid

Gas flow meters are used for measuring the flow or quantity of a moving gas in an enclosed pipe or passage.

Flow meters (flowmeters) and flow sensors are devices used for measuring the flow rate or quantity of a moving fluid or gas

Gear pumps use intermeshing gears to pump various types of liquids.
