What is a Flow Meter and how does it work?

Video source:

A flow meter (or flow sensor) is an instrument used to measure linear, nonlinear,mass or volumetric flow rate of a liquid or a gas.When choosing flow meters,one should consider such intangible factors as familiarity of plant personnel,their experience with calibration and maintenance, spare parts availability,and mean time between failure history, etc., at the particular plant site.

It is also recommended that the cost of the installation be computed,only after taking these stepsThe different sensors include dial, in-line, ultrasonic, orifice plate,totalizing meters, variable area, venturi, or with switch output.The different designs of the flow meters have a variety of applications.

Know More about Flow Measurement

If you need to know the flow rate in you pipe, or river, that when you need a flow meter. So, flow meter is the instrument that can finish the flow measurement.

Flowmeters consist of a primary device, transducer and transmitter.

The transducer senses the fluid that passes through the primary device.

The transmitter produces a usable flow signal from the raw transducer signal.

These components are often combined, so the actual flowmeter may be one or more physical devices.

Different types of flow meters are available for different application,

and depending upon the requirement, a careful selection of flow meter is made.

For e.g., we prefer vortex flow meters flow steam flow measuremnet. And we like the ultrasonic flow meters for non-contact pipe flow measuremnt.

Turbine type flow meter cannot be used for measuring the flow in an unclear liquid

(waste water or corrosive liquids).

Electronic flow meter, are industrial digital flow meters for fluid flow rate measurement. Electronic flow meters types like: MagneticVortex, and Ultrasonic flow meters.

While magnetic, vortex, and ultrasonic–are neither exclusively nor exhaustively electronic in nature. They do represent a logical grouping of flow measurement technologies.

All electronic flow meters have no moving parts, are non-intrusive, and are made by electronics technology.

Magnetic flowmeters, are the most directly electrical in nature, deriving their first principles of operation from Faraday’s law. Vortex meters depend on piezoelectric sensors to detect vortices shed from a stationary shedder bar. And today’s ultrasonic flowmeters owe their successful application to sophisticated digital signal processing.
