Flow meter


Flow measurement is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. The common types of flowmeters with industrial applications are listed below:a) Obstruction type 
b) Inferential 
c) Electromagnetic
d) Positive-displacement flowmeters, which accumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow.
e) Fluid dynamic 
f) Anemometer
g) Ultrasonic
h) Mass flowmeter.
