Ball provers calibration

We carry out on your site in onshore or offshore the calibration of ball pipe provers by the waterdraw calibration method according to the API 12-2-4 standard or using a master meter according to API 12-2-5.
We provide the necessary equipment: pump, hoses, fittings, pulses counter, tank provers and master meter, pressure gauges and thermometers with calibration certificates.
We also provide equipment for:
- extraction and transport of sphere (suction cups and extractor, net)
- sphere inflation and measurement (pump, hoses and fittings and circometers)

We are able to clean your ball pipe provers before calibration and only with clear water, which considerably reduces the cleaning time, saves you additional costs related to the use of solvents, and preserves the environment.

We have COFRAC accreditation n° 2-7290 for the calibration of piston/compact provers (scope available on www.cofrac.fr) according to standard NF EN ISO/IEC 17025, allowing the guarantee of rigorous work and of quality that we apply in all our fields.

Compact/piston provers calibration

We carry out on your onshore or offshore site the calibration of piston/compact provers by the waterdraw calibration method according to the API 12-2-4 standard
For this service, we have COFRAC accreditation on site n° 2-7065 (scope available on www.cofrac.fr) according to the NF EN ISO/IEC 17025 standard, guaranteeing rigorous and quality work.
We provide the necessary equipment: pump, hoses, fittings, pressure gauges and thermometers with calibration certificates.
We can also provide the necessary tank provers, or can use your own (if they have a calibration certificate from an accredited laboratory according to ISO/IEC 17025 standard)
