Category: Type Flow Meter

Type of Flow Meter 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:

• Obstruction type (differential pressure or variable area)
• Inferential (turbine type)
• Electromagnetic
• Positive-displacement flowmeters, which accumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow.
• Fluid dynamic (vortex shedding)
• Anemometer
• Ultrasonic
• Mass flowmeter (Coriolis force).

Flow measurement methods other than positive-displacement flowmeters rely on forces produced by the flowing stream as it overcomes a known constriction, to indirectly calculate flow.  Flow may be measured by measuring the velocity of fluid over a known area. For very large flows, tracer methods may be used to deduce the flow rate from the change in concentration of a dye or radioisotope
