Study Notes
Flowmeters
- Differential Pressure Flowmeters rely on forces produced by the flowing stream as it overcomes a known constriction to indirectly calculate flow.
- Positive Displacement Flowmeters accumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow.
- Velocity Flowmeters rely on measuring the velocity of fluid over a known area to measure flow.
Turbine Flowmeters
- Turbine Flowmeters are used in industrial applications.
Tracer Flowmeters
- Tracer Flowmeters rely on deducing the flow rate from the change in concentration of a dye or radioisotope, particularly suitable for very large flows.
