The roots of CWI lie in the meter proving industry. Our sister company C&W Meter Service, Inc. is the leader in the mobile pipeline, petroleum, and petrochemical meter proving industry. It is no wonder that CWI would offer Meter Proving service to the rail road industry. The only way you will be able to accurately know fuel consumption volume is with an accurate meter. The only way to have an accurate meter is to calibrate your meters to a NIST certified field standard. This process is done onsite for both your convenience and to provide the most accurate calibration possible.

Allow CWI to develop a calibration schedule for all of your chain-of-custody and inventory control meters today and never worry about the accuracy of fuel usage data you are reviewing. Meter calibration is a small expense versus the enormous potential for revenue loss or environmental impact due to an inaccurate fuel meter.
