Question

How do you measure fluid flow?

Answer 1

Hint: We could define the flow meter as the device that is used for the measurement amount of liquid flowing through a pipe along with the quantity of the liquid streaming. You may recall that there are a number of flowmeters used which is based on different principles. Name them.

Complete step-by-step solution:
In the question we are asked to find out the methods by which we measure fluid flow. We could name the quantification of bulk fluid movement as ‘flow measurement’. Some of the common types of flowmeters with industrial applications are the following:
(1) We have an obstruction type flow meter that is based on differential pressure or maybe variable area.
(2) We have inferential flow meters which is basically turbine type.
(3) Another class of flowmeters are the electromagnetic flowmeters.
(4) Then we have positive displacement flowmeters, which is basically known to accumulate a fixed volume of fluid and the number of times the volume is filled is counted so as to measure flow.
(5) Then we have fluid dynamic flowmeters.
(6) Another class of flowmeter is the anemometer.
(7) We also have the ultrasonic flow meters.
(8) Mass flowmeters that are based on Coriolis force is another class of flowmeters.

Note: The methods by which the flow measurements are taken other than the positive displacement flowmeters are known to depend on the forces that produced by the flowing stream. This force results from overcoming the known constrictions and thereby indirectly calculating the flow.
