Patent ID: 8626466

Claim:
A flow meter validation system, comprising: an ultrasonic flow meter configured to: provide information indicative of a parameter of fluid flow through the ultrasonic flow meter; and store a baseline value that defines a preferred range for the parameter of fluid flow; and display logic coupled to the ultrasonic flow meter; wherein the display logic is configured to: receive from the ultrasonic flow meter: the baseline value; and a value of the parameter; determine a possible range of values of the parameter that exceeds the preferred range of values of the parameter; determine, based on the baseline value, a baseline portion of the possible range designating preferred upper and lower limit values of the parameter; determine value of the parameter relative to the possible range and the baseline portion of the possible range; and provide a display of the information, the display comprising: an indication of the possible range of values of the parameter; an indication of the baseline portion of the possible range; and an indicator of the value of the parameter relative to the indication of the possible range and the indication of the baseline portion of the possible range.
