Flow Controllers

Malema offers advanced flow controllers using Coriolis and Ultrasonic technologies engineered for chemical dosing and flow control applications in various industries, including high-purity applications for controlling the flow of DI water, chemicals and slurries. Many of these closed-loop flow controllers are designed to meet the specific installation requirements of large semiconductor equipment manufacturers to be used in specific tools.

Coriolis Mass Flow Controllers, with extreme accuracy of ±1%, are immune to changes in fluid conditions such as density, viscosity or the presence of entrained gases in liquids and slurries. Thus, having calibrated on DI water, they can be used on different process fluids without adjustments for density or viscosity changes. The unique sensor design and advanced firmware ensure quicker control response and improved accuracy.

Ultrasonic Flow Controllers offer high accuracy and repeatability specifications for measuring liquids and slurries with the help of the most advanced filtering and digital signal processing techniques used in the industry. Featuring all-wetted parts made PTFE/PFA providing corrosion resistance, these flow controllers are trusted around the globe based on tens of thousands of successful installations.

Malema's customer support and application engineers are ready to offer guidance on selecting the right flow controller technology for the application. Contact us to get started.

Malema Flow Controllers FAQ

What is a flow controller?

A flow controller regulates the rate of fluid or gas in a system, maintaining consistent flow regardless of changes in pressure or system conditions.
What are the different types of flow controllers?
Flow controllers are available in the following types:
- Coriolis flow controllers regulate mass flow with high accuracy by directly measuring the mass of fluid passing through. They are ideal for precise dosing and chemical processes where exact amounts are critical.
- Ultrasonic flow controllers regulate flow by measuring fluid velocity using sound waves, allowing non-invasive monitoring. They are well-suited for applications where maintaining pipe integrity and avoiding leaks is important.
What is the difference between an ultrasonic and a Coriolis flow controller?

Ultrasonic controllers measure and control flow using sound waves and are suitable for non-invasive monitoring. Coriolis controllers provide direct mass flow control with high precision and are ideal for complex chemical-intensive applications or applications that may include bubbles or foaming.
