Master Meter Proving Stand

Master Meter Proving Test Stand

Whether you require annual proving for regulatory purposes, repair, testing, or accuracy verification in which meter performance is in question, our experienced, factory trained and certified technicians will ensure all of your needs are met.

Customers who have purchased or are purchasing meters in government regulated, custody transfer or plant balance applications have been challenged by:

  • Increased demands by regulatory bodies
  • Difficulties with in situ meter proving
  • Long turnaround delays
  • High maintenance costs related to off-site meter proving

In an effort to support our valued Customers, Spartan has invested in a Master Meter Proving Stand.

This factory certified NIST traceable meter calibration stand provides volumetric and density calibrations on a wide range of meter technologies and sizes. The stand utilizes multiple Micro Motion master meters calibrated to accuracy specifications of better than 0.05%.

With a tank capacity of 8,500 liters and two parallel centrifugal pumps, the stand is capable of cycling clean water through test meters at rates ranging from 15 to 4,000 liters/minute. The stand has the capabilities to prove ½” all the way up to 6” Micro Motion and Rosemount Mag meters to within their published factory specifications. Additionally, Vortex meters from ½” to 6” and Micro Motion Meters as large as 10” can be verified for good repeatability and accuracy. All of these sizes and types of meters in the past would have been sent out of country for calibration and verification.

By utilizing a sophisticated ROC800L proving flow computer, the Master Meter Proving Stand gathers the I/O, performs all proving calculations, and comes with professional calibration reports that are stored to a Customer profile database.

Our hydraulic ram mechanism allows for quick and boltless installation of test meters, enabling us to offer same day turnaround capabilities on emergency situations with standard turnaround times of 1-2 weeks on meters that are provided pre-cleaned.
