This is a means of measuring the flow of water in a given parameter at a given time The flow meter is the piece of equipment used to make the measurement
A device that measures the quantity of product flowing through a pipeline It provides data for controlling products in a pipeline and for accounting purposes
An instrument for monitoring, measuring, or recording the rate of flow, pressure, or discharge of a fluid, as of a gaseous fuel. Device that measures the velocity of a gas or liquid. It has applications in medicine as well as in chemical engineering, aeronautics, and meteorology. Examples include pitot tubes, venturi tubes, and rotameters (tapered graduated tubes with a float inside that is supported by the flowing fluid at a level that depends on the flow rate). Ultrasonic flow meters, in which reflecting ultrasound off a flowing liquid leads to a Doppler shift (see Doppler effect) that is calibrated to provide the flow rate of the liquid, have important industrial applications and have also been used to measure arterial blood flow
