C&W Meter Service offers a broad range of pipeline custody transfer meter proving services up to a maximum flow rate of 18,000 bph (12,600 gpm). All our proving equipment is NIST traceable, and is designed and operated per the guidelines of the American Petroleum Institute (API) for custody transfer meter proving. pipeline

C&W maintains a fleet of portable Small Volume Captive Displacer provers to meet your pipeline meter proving needs. All pipeline proving connections are made via petroleum industry standard hammer style fittings for reliable, leak-free operation. All our proving rigs are equipped with generator power for independent, reliable operation, as well as, an on-board drain system for efficient draining of the proving equipment. Prover operation and report generation is done by computer running the PROVEit8 software program supplied by Flow-Cal, Inc.

The measurement technicians employed by C&W have many years of pipeline meter proving experience and are trained in the API guidelines for custody transfer meter proving. The health and safety work practices of all C&W employees is governed by our company Health and Safety Manual which is routinely audited by companies like NCMS, DISA and PICS. Our Health and Safety plan details are accessible via ISNetworld. Safety is the number one priority for C&W Meter Service.

To accommodate the high flow portable proving requirements for our customers, C&W designed and built a portable High Flow proving rig complete with Small Volume Prover and 12″ Master Turbine Meter. The 12” Master Turbine Meter provides a transfer standard for proving microprocessor based flow meters like ultrasonic or Coriolis meters that require long sample times to meet API custody transfer requirements. The Direct Master Meter proving method utilized by C&W Meter Service is in accordance with the standards set by the newly revised API MPMS Chapter 4.5 Master Meter Provers, Third Edition November 2011. The high flow trailer mounted proving system has a maximum flow capacity of 18,000 Bph (12,600 gpm) of refined petroleum products like gasoline and distillates. The rig uses 12″ articulating loading arms that are hydraulically actuated for fast, easy connection to the pipeline. They provide flexible hookup from the trailer’s left side, right side or rear. In addition, the arms can be crossed to accommodate pipeline flows from left-to-right or right-to-left. The proving rig is fully powered by an onboard diesel generator for independent, reliable operation. On-site densitometer proving and calibration services are also available using a Pycnometer standard. This service is performed in accordance with API MPMS Chapter 14.6, Continuous Density Measurement and is traceable to the National Institute of Standards and Technology (NIST).
