Repair, Resize, Upgrade or Refurbish

Repairing a flow meter can only be done by an expert. Polycontrols offers the most professional service when it comes to the refurbishing of your instruments. Thanks to the expertise acquired over the last 35 years, our metrology technicians have mastered not only the volumetric and mass flow calibration but also the necessary techniques to make most repairs on popular thermal mass flow meters and controllers. More specifically we are able to;

  • Upgrade or rescale the flow range
  • Recalibrate under new operating conditions
  • Replace defective parts with our 2000 spare parts inventory
  • Disassemble, clean and decontaminate the instrument
  • Clean and degrease for Oxygen service

Gas meters have moving parts that are subject to wear and adjustments might be required during routine maintenance and calibration. That’s why we also offer maintenance and repair of internal mechanical parts in order to deliver an instrument with precise readings that can be returned to service.

Our specialists are able to perform modifications or refurbishing on most brands of flow meters
