Abstract
To provide a fault-tolerant architecture to supply electrical operating power in fluid flow measurement applications, apparatus and associated systems, computer program products, and methods include an intelligent power module with redundant and electrically independent battery strings to supply regulated voltage to electronic fluid flow measurement data processing circuitry. In a preferred implementation, the intelligent power module transmits operating power and battery status information over a two wire interface. Circuitry may encode information about the status of individual battery strings in a DC supply voltage. The fluid meter processing circuitry operates from the DC supply voltage and decodes the battery status information. Preferred embodiments may also include a switched-mode power supply capable of extracting substantially all available stored energy capacity from each of the battery strings, each of which is electrically isolated by a unidirectional current circuit.
