Alicat Whisper™ MW-Series Low-Pressure Drop Mass Flowmeters, Digital Display, SCCM

Provides accurate real-time mass and volumetric flow readings with minimal pressure drop
  • Instant warm-up
  • Ninety-eight pre-loaded gas calibrations
  • One-hundred millisecond control response
  • IP40 rating
These low-pressure drop mass flowmeters utilize laminar differential pressure technology to deliver precise mass flow measurements for over 130 different gases. With a rapid control response time of just 100 milliseconds, they integrate easily into test stands, enabling immediate and accurate verification without the need for warm-up.

Designed to minimize pressure drop—as low as 0.07 psid—these flowmeters are ideal for applications with limited source pressure. Each unit comes pre-loaded with 98 standard gas calibrations that can be easily switched without compromising accuracy.

These stand-alone devices measure mass flow, volumetric flow, temperature, and absolute pressure, with readings shown in standard cubic centimeters per minute (SCCM). Additional features include a backlit monochrome LCD display, a data I/O port for seamless data logging to a computer, and versatile mounting options—even allowing for upside-down installation.
