What are flow meters?
Flow instruments, flow controllers or flow control valves measure the amount of flow in mass (Weight) or volume of gas, liquid or solids passing by in a process line per time unit. Flow can be measured with a mechanical turbine flowmeter with rotating internal parts or an electromagnetic flowmeter without any mechanical parts. Both flowmeters are used to measure large volumes of flow. To measure mass flow a thermal mass flowmeter should be used.
Types of Flow meters
Flow meter applications
Flow measurement in process and instrumentation systems is done with flowmeters or with differential pressure instruments. They can be found in the following flow applications: Air flow control, liquid flow control, purge gas flow control, analytical flow measurement, high-velocity stream measurement, low flow gas applications, slurry applications, energy-fuel flow measurement, cryogenic flow measurement, combustion fuel control, Fluid streams like, slurry, sewage, wood pulp, chemicals, water treatment plants, high viscous fluids, food processing, flow measurement of pulp, blending systems for the petroleum industry, Biopharmaceutical bioreactors and many more.
