Claim 18:
19. A self-proving meter comprising a computing device configured to:
provide a manual capture mode in response to receiving an input;
receive a capture input in the manual capture mode;
in response to receiving the capture input, establish one or more baseline flow volume or flow rate measurements for the meter, the meter configured to measure a flow through the meter in accordance with flow driven rotation within the meter, wherein the one or more baseline flow volume or flow rate measurements comprise measurements established manually at a plurality of load states of a system connected to the meter comprising a plurality of separate load devices, the load states comprising a load of the system of each of the plurality of separate load devices independently, and a plurality of combinations of the plurality of separate load devices;
obtain a current flow volume or flow rate measurement for the meter in accordance with flow driven rotation within the meter, wherein the current flow volume or flow rate measurement comprises a measurement of the system corresponding to one of the plurality of load states; and
determine a proving result in accordance with a comparing of the current flow volume or flow rate measurement corresponding to one of the plurality of load states with a corresponding baseline measurement of the one or more baseline flow volume or flow rate measurements, wherein the proving result comprises one or more of percent proof, percent accuracy or percent error for the meter.
