Alicat portable gas flow meters measure and display mass flow, volumetric flow, line pressure or barometric pressure, and gas temperature. They are precision scientific instruments whilst being rugged and ready for use in the real world. Quality is paramount and they are backed by a Lifetime Warranty.

Portable gas flow meters make audits, GC checks and calibrations fast and easy. They also fulfil a number of lab measuring functions all within the one device. All portable flow instruments offer laboratory-grade accuracy and multivariate readings that update 1000 times a second. Engineering units (Ln/min, SLPM, mln/min, sccm etc) are configurable and no conversion factors are required. Up to 130+ gases are stored onboard to ensure that the stated accuracy remains true regardless of the gas type or created mixture.

AFS–Portable Gas Flow Calibrators

A portable gas flow standard that is ready for anything.

When a calibration process requires the utmost accuracy, the AFS flow standard delivers. It features Alicat’s most advanced calibration for optimal performance across changing temperatures, plus an on-board relative humidity sensor to maintain its accuracy all the way up to 100% RH (non-condensing). These advancements make possible a 0.75% of reading accuracy spec that requires no additional full-scale component. Low pressure drop allows calibration of volumetric flow rates with minimal impact. Averaged measurements and onboard data logging make it easy to gather multivariate flow data.

  • Full scale from 5sccm to 50SLPM
  • Turndown ratio: 200:1 when flowing air; 20:1 when flowing other gases or gas mixes
  • Typical measurement response time constant: 5-10 ms
  • No warm-up time required

MB–Portable Gas Mass Flow Meters

Laboratory-grade flow verification, anywhere you need it.

Alicat’s portable flow flowmeters make calibration or validation simpler and faster by reducing downtime and disruption. Instant-on and real-time readings for multiple gases across wide flow ranges ensure periodic checks can be completed within just a few minutes.

  • Available ranges: max 0-5000 slpm, min 0-0.5 sccm/0-500 sμlm
  • Turndown ratio: 200:1 (standard gases) or 100:1 (corrosive gases)
  • Standard accuracy calibration, NIST-traceable: +/- (0.8% of the reading + 0.2% of the full-scale range)
  • Optional high-accuracy calibration, NIST-traceable: +/- (0.4% of the reading + 0.2% of the full-scale range)

MWB–Low Pressure Drop Portable Gas Mass Flow Meters

Measure flow with minimal system impact, anywhere you need it.

  • “Whisper” series portable flow meters with low pressure drop are the perfect measuring and 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.
  • Available ranges: max 0-1000 slpm, min 0-0.5 sccm/0-500 sμlm
  • All other specifications are as per the MB Series

Alicat portable measuring and calibration devices are available for gas flow, liquid flow and pressure calibration checks.
