(flō'mē-tĕr),
A device for measuring velocity or volume of flow of liquids or gases.

flowmeter

/flow·me·ter/ (flo´me-ter) an apparatus for measuring the rate of flow of liquids or gases, often named for the method employed, e.g., ultrasound f.

flowmeter

a device that regulates and measures the flow of a fluid or gas. In an anesthetic gas machine it is the flowmeter that measures gases by speed of flow, according to their viscosity and density. Also called rotameter and Thorpe tube.

flow·me·ter

, flow meter (flōmē-tĕr)
1. A device for measuring the flow of liquid or gas.
See also: pneumotachometer
2. A device for controlling the flow of medical gases, as in the delivery of air or oxygen to a nebulizer.

flowmeter

An instrument for measuring the rate of flow of a gas or liquid. Flowmeters are important in anaesthetic practice.

A device for measuring velocity or volume of flow of liquids or gases.

flowmeter,

n a physical device for measuring the rate of flow of a gas or liquid, such as with nitrous oxide.

flowmeter

an apparatus for measuring the rate of flow of liquids or gases, particularly anesthetic gases. Called also rotameter.

Bourdon flowmeter
based on the straightening of a flexible metal tube as gas pressure increases. Has limitations, especially at very low flow rates.
