Instrument: Mechanical Flowmeter

Acronym: Mechanical Flowmeter

External Identifier:

Description

Manufactured by General Oceanics, a mechanical flow meter is used with plankton tows to determine the volume of water which flows through the net. Flow meters are also used in rivers, estuaries, canals, sewer outfalls, pipes, and harbor entrances to determine water velocity and flow distance information.
