C&W Meter Proving Services is your partner of choice for custody transfer and mission critical flow measurement proving services. With a wide variety of state-of-the-art tools, C&W can meet the most demanding meter proving needs in the field or in our shop. The key to our success and your satisfaction is using the right tool for the job.


To accommodate the high flow portable proving requirements for our customers, C&W has available a portable High Flow proving rig (SVP 34) complete with Small Volume Prover (100 Gal) and 12″ Master Turbine Meter. The 12” Master Turbine Meter provides a transfer standard for proving microprocessor based flow meters (Ultrasonic or Coriolis) that require long sample times to meet API custody transfer requirements. The Direct Master Meter proving method is in accordance with the standards set by the newly revised API MPMS Chapter 4.5 Master Meter Provers. The high flow trailer mounted proving system is built with ANSI #300 class piping with a maximum flow capacity of 18,000 BPH (12,600 GPM) of refined petroleum products. The rig uses 12″ articulating loading arms that are hydraulically actuated to provide flexible hookup from the trailer’s left side, right side or rear and can be crossed to accommodate pipeline flows from left-to-right or right-to-left.
