Flow Calibration - ISO/IEC 17025

Polycontrols is one of the few flow calibration laboratory accredited ISO / IEC 17025 for the calibration of gas flow meters and liquid flow meters. All our flow calibrations are traceable to NIST with an unbroken chain of comparison.

Polycontrols' flow calibration laboratory is certified under ISO / IEC 17025, the highest recognition in flow calibration, for the calibration of gas flow meters within a range of 5 sccm to 6000 slpm and liquids flow meters within a range of 0.378 kg/min to 41.58 kg/min.

At Polycontrols' flow calibration laboratory, our main objective is to respond to the customers' specific requirements, by executing a precise and reliable flow calibration service in a timely manner. To achieve our goals, our flow calibration services include:

In-Lab Flow Calibration

  • "10-day service" for standard flow meter calibrations and "same day" service for emergency calibrations
  • Standard flow calibration gases : Air, N2, Ar, He, H2
  • Standard flow calibration fluids : Water, MIL and Oil
  • Detailed as found and as left flow calibration data; Notification of any out-of-tolerance conditions and historical records of every flow calibrations
  • NIST traceable flow calibration reports meeting biomedical and aerospace regulatory requirements
  • Calibration, modification and refurbishing of all major brands of flow meters
  • Extensive inventory of flow meters and spare parts for fast calibration services

We are devoted to offering precise, reliable and fast flow calibration services that meet our customers' expectations!

In-Situ Flow Calibration

Polycontrols' on-site flow calibration services provide an effective flow calibration solution for customers who need to certify entire process loops under real operating conditions. Each one of our on-site flow calibrations meets the same strict requirements as calibrations carried out at our flow calibration laboratory.

Working with an ISO/IEC 17025 flow calibration laboratory is a promise of the quality and the effectiveness of your service
