Mass Flow Controllers & Meters

Portable gas flow standards

Pressure based mass flow instrumentation for top performance. 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.

  • 0.6% of reading accuracy on most flow instruments
  • 4 ms response time
  • No warm up
  • Four process variables
  • Built in display
  • Industrial protocols
  • Pressure compensation
  • Temperature compensation
  • Wide dynamic flow ranges

FP-25 is weatherproof, designed for outdoor calibration of particulate matter (PM) ambient air samplers.

The MB series is suitable for most flow measurement applications, with models that can measure flow rates as high as 5000 slpm or as low as 0.00005 sccm.

Choose an MBQ when your line pressures are high (145-305 psig).

The MWB series is best for low pressure drop applications and for reducing pneumatic response time at flow rates of 50 scccm or less.

Alicat’s PCU is a portable transfer standard that combines up to three individual flow meters for a very wide usable range. Choose a PCU when the range of a single flow meter isn’t enough for your calibration needs.

Flow Verification for a Gas Chromatograph (MB)

Check primary and by-pass flows to maintain optimal GC performance.

Calibration of an Air Sampling Canister (MWB)

Low pressure drop enables non-intrusive volumetric flow calibration.

Calibration of multiple flow instruments (PCU)

Three overlapping ranges makes the PCU extremely versatile.

Audit of an air sampler (FP-25)

Perform flow audits in any weather with highest accuracy.
