Metrology & Calibration

In-field & in-house calibration and metrology with portable transfer standards

For metrology and calibrations labs and field service teams looking to simplify calibration and validation of flow equipment, portable, NIST-traceable calibration equipment means technicians have the tools they need — whether in a state-of-the-art metrology lab or at a remote, outdoor site.

  • Accuracy to ±0.5% of reading or ±0.1% of full scale makes a 4:1 TUR readily accessible.
  • Battery-powered portable devices with standup interfaces don’t every require an outlet, computer, cord or wire when you’re in the field.
  • Multivariate measurement devices let you measure the environmental factors with the flow rates, maintaining the accuracy of each of your instruments.

Wireless transfer standards for in-field calibration & validation

Battery-powered, portable flow meters with high-accuracy calibrations are transfer standards which don’t need outlets, cables, or computers. You can control and monitor the device using the standup interface.

Rechargeable flow meters can be easily added into a flow line at any point for rapid, at-line system verification. If your devices are still in spec, they never need to be disconnected from the line.

Multivariate meters fully compensate for ambient conditions

Calibrating rotameters requires correction to specific standard or normal temperature and pressure conditions.

Alicat devices simultaneously measure mass flow, volumetric flow, temperature, and pressure in real time, so you can ensure your devices are calibrated to the right environmental conditions.

Calibration kits for any gas flow and range

Metrology labs and field technicians work with a huge variety of flow devices and gases. The PCU has a dynamic range of up to 1,000,000:1 and is a portable, rugged device with a standard accuracy of ±0.5% of reading or ±0.1% of full scale.

The COMPOSER Gas Select features means you can calibrate on any gas, including your own mixtures, and switch between gases at any point, no recalibration required.

Calibration, validation, and verification

Verification is an evaluation to make sure a specific piece of equipment is operating to its originally-stated specifications, while validation is a broader system check to ensure the piece of equipment is filling its intended purpose. Calibration ensures the instrument is conforming to an external reference standard.

NIST-traceable transfer standards

All Alicat devices undergo NIST-traceable calibrations and can be used as NIST-traceable transfer standards for in-house calibration, validation, or verification.
