What are flow controllers?

Flow controllers, or mass flow controllers, refer to electrical sensor devices that are capable of measuring and controlling the flow of different liquids and gases. Each flow controller, however, is usually engineered in such a way that it can control only a specific type of fluid or gas, and at a specific flow rate range. 

Being designed in such a way, flow controllers can control flow rates automatically through an auto-set flow rate received through the electric signal.

Types of flow controllers

The types of flow controllers depend on the flow rate. This way, flow controllers can be categorised into two types:

Volumetric flow

Flow controllers, having volumetric flow rates, measure the flow of liquid or gas with respect to the temperature and pressure.

Mass flow

Flow controllers, having mass flow rates, are suitable for broader industrial use. They are essential to establish accurate control.

Applications of flow controllers

Flow controllers have a wide range of applications across different industrial processes and sectors. They are generally used in oil and gas industries, the water treatment sector, power plants, and manufacturing sectors. Nevertheless, flow controllers are more commonly used in technical applications like:

• Cylinder speed control
• Mould water cooling
• Medical product coating
• Pig velocity control
