Flow Metering

GIL provides primary and secondary calibration services for pneumatic, hydraulic and electronic instruments. Our calibration procedures are in line with ISO17025 requirements.

We are certified by local standard boards and we provide primary metering systems for proving meters and for calibrating measurement devices.

GIL Automation offers on-site and in-house flow meter calibration for a wide range of petroleum-based products, up to 5000 litres per minute. Our truck-mounted volumetric proving vessels are available for on-site flow meter calibration of light petroleum products and some chemicals. All proving vessels are traceable to NIST and re-certified yearly. Calibrations are performed according to NIST Handbook 44 guidelines.

We have prover tanks from Seraphinn in US for range from 500litres per minute up to 5000 litres per minute. Our Offshore skid has a prover tank (primary standard) and a master meter ( secondary standard) on board in line with DPR requirements.

Some of the equipments we certify include:

      • Flow meters (PD Meters, coriolis mass meters, turbine meters etc)
      • Metering systems such as provers (using master meters and provers), custody transfer meters etc.
      • We also lease our equipment for mobile offshore use.

We have deployed Laboratory information management system (LIMs) to meet the requirements of our clients.

Furthermore, our equipments are traceable to NIST and API certified laboratories and metereology centers.

In conjunction with our technical partners, GIL provides and support skid solutions such as:

      • Metering skids
      • Wellhead control panel
      • Hydraulic Power Units
