The ACU10FDR low-pressure-drop gas mass flow controller is equipped with a proprietary high-flow electromagnetic valve, making it ideal for controlling mass flow even when system pressure is nearly unavailable. Its minimal pressure differential ensures the least possible impact on the system, enabling precise flow control under near-atmospheric conditions while significantly reducing system response time. We can customize the valve and PID control features based on your specific application parameters, guaranteeing fast, stable performance with minimized pressure loss.
Range: (150-3000) SLM

The ACU10FDR Low-Pressure-Drop Gas Mass Flow Controller features a proprietary, high-flow electromagnetic valve, designed specifically for controlling mass flow rates even in situations where system pressure is nearly unavailable. Its low-pressure differential ensures minimal impact on the system, enabling precise flow control under near-atmospheric conditions while significantly reducing system response time. We’ll customize the valve and PID control functionality based on your specific application parameters, ensuring the product delivers fast, stable performance with optimized, low-pressure loss characteristics.
The ACU10FDR series of low-pressure differential gas mass flow controllers is widely used across various industries, including process manufacturing, food analysis, and analytical testing and measurement applications. Featuring multi-variable measurements and a highly adjustable 50:1 range, a single ACU10FDR controller can effectively replace the functionality of multiple devices. With an accuracy of 1%, repeatability of 1%, and a control response time of less than 200 milliseconds, these controllers ensure reliable operation of process gases.
