Malema offers advanced flow controllers using Coriolis and Ultrasonic flow measuring and controlling technologies. These flow controllers are designed for chemical dosing and flow control applications in various industries, including high-purity applications for controlling the flow of DI water, chemicals and slurries. Additionally, 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. With two distinct technology options – Coriolis and Ultrasonic – Malema offers a range of flow controllers to best fit your application.
Coriolis Flow Controllers – With an extreme accuracy of ±1%, Malema’s patented Coriolis flow sensor used in the Coriolis mass flow controller is 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 further adjustments/corrections for density or viscosity changes. Thanks to the unique sensor design and the advanced firmware that employs innovative signal processing and control algorithms, faster control response and accuracy are ensured.
Ultrasonic Flow Controllers - Malema 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, Malema Ultrasonic Flow Controllers are trusted around the globe with their tens of thousands of successful installations.
Malema's customer support and application engineers are well-trained and ready to offer guidance on selecting the right flow controller technology for the application.
