REAL-TIME FLOW COMPENSATION IN USAGE ACCUMULATION

摘要

Technologies are described herein for compensating for inaccuracies in flow measurement in real-time during accumulation of usage. A pulse count indicating an amount of flow in a meter over a measurement period is read. An average flow rate through the meter for the measurement period is determined and a correction factor is looked up from a table based on the average flow rate. A total usage accumulator for the meter is then updated with the amount of flow over the measurement period based on the pulse count and the correction factor.

1. A method for compensating for inaccuracies in flow measurement in a meter during accumulation of usage, the method comprising steps of:
reading, by a microcontroller in the meter, a pulse count indicating an amount of flow in the meter over a measurement period; determining, by the microcontroller, an average flow rate through the meter for the measurement period; looking up, by the microcontroller, a correction factor from a table based on the average flow rate; and updating, by the microcontroller, a total usage accumulator with the amount of flow over the measurement period based on the pulse count and the correction factor.
