Stopping an operational process for validation or calibration is a necessary evil.  Alicat’s portable flow calibrators make this procedure more palatable by reducing the downtime and disruption to your process.  Instant-on and real-time readings for multiple gases across wide flow ranges let you get in and out quickly.  Portable flow meters make system checks, calibrations and audits fast and easy.  All portable flow instruments offer laboratory-grade accuracy and multivariate readings that update 1000 times a second. 

The MWB “Whisper” series portable flow meters with low pressure drop are the perfect calibration instruments for mass and volumetric flow rates. Low pressure drop minimizes system impact, enabling flow measurement at near-atmospheric pressures or when there is little available system pressure.

Alicat’s MWB “Whisper” series portable flow meters can be custom built with your choice of options.  Choose your communications protocol, display, process connections, elastomers, flow totalizer, and calibration.  Need further customization?  Contact us and we'd be happy to help you build the instrument you need.

Each flow meter comes with a NIST-traceable calibration certificate, an Alicat operating manual, a micro-USB charging cable and AC wall adapter.
