| GCI has developed a multi-probe flow RATA program called Precision Flow© that includes the Electronic Flow measurement portions of Methods 2H and 2G. GCI uses four probes mounted to the stack ports that allow several readings at each point with Delta P, Temperature and Angle averaged for each reading. This provides greater accuracy and also allows the Flow RATAs to be performed in one hour per load. This method reduces the high bias associated with manual flow methods but does not drastically affect the cost of the testing. Precision Flow© follows USEPA Methods 2G and 2H without modifications. GCI uses Method 4 for moisture determinations and Precision Flow© can be performed on the same day as the gas RATAs. The yaw angle determination described by Method 2G is used for all test runs and the flow RATA can still be completed in one hour per load. Contact GCI to Request a Quote or Testing Information. |
