Flow Instruments

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. There are different principles of flow measurement. Flow meters are referred to by many names, such as flow gauge, flow indicator, liquid meter. 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 mass flow controller for very small flows is. Accuracy and repeatability of flow instruments are important features of the flowmeters and will be different with every type of flow instrument or flow controller.

Types of Flow meters

Coriolis Mass flowmeters
Electromagnetic flowmeters
Flow controllers/ flow switches
Flow indicators
Positive displacement flowmeters
Thermal mass flowmeters
Turbine flowmeters
Ultrasonic flowmeters
Variable area flowmeters
Vortex flowmeters

 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.

 How to select flowmeters?
