Alicat Whisper™ MCW-Series Low-Pressure Drop Mass Flow Controllers, SLPM

Accurately measures and controls real-time mass and volumetric flow readings with minimal pressure drop

These low-pressure drop mass flow controllers, featuring a fast control response time of just 30 milliseconds (ms), offer quick integration into test stands for accurate verification without any warm-up time. Controllers create minimal pressure drop, making them ideal for systems with limited source pressure. They are capable of measuring and controlling flow generated by both positive pressure and suction. Real-time monitoring of flow, pressure, and temperature is available directly on the display screen.

The controllers come with 98 pre-loaded gas calibrations, which can be seamlessly switched while maintaining accuracy. The stand-alone units measure mass flow, volumetric flow, temperature, and absolute pressure, with flow rates displayed in standard liters per minute (SLPM). Additional key features include an LCD display with backlight, a data I/O port for logging data to your computer, and flexible mounting options, including upside-down installation.
