The ever evolving use of blended fuels for automotive and truck use require the right standards and process to achieve consistent metering accuracy and optimum loss prevention. The C&W loading rack proving trailers are equipped with modern in-line dynamic displacer Small Volume Provers (SVP) and a unique assortment of hoses, cables and electronics to provide no hassle pulse based meter proving for all rack designs and products being delivered (gasoline, ethanol, ULSD, biodiesel, fuel oil, jet fuel).

The Small Volume In-Line Provers utilized by C&W provide fast, efficient proving of rack meters.  The use of dynamic displacer Small Volume Provers for modern truck loading racks has become the proving method of choice primarily due to the blending requirements mandated by the use of ethanol in all motor fuels. The in-line pulse proving method has become the standard for most major oil companies that upgrade their truck loading racks with newer, more modern blending and automation equipment. The pulse type SVP method provides many benefits:

1. Safer proving operation – no climbing a ladder to read liquid level
2. In-line proving system – no potential for spills
3. Prove rack meters while filling customer trucks – Efficient! – Saves Money!
