ABSTRACT:
A fluid meter comprises at least three sensors each having an output dependent on a respective characteristic of the fluid to be monitored, circuitry to combine the outputs of two of the sensors to provide a measurement of mass flowrate of the fluid, and to combine the outputs of the three sensors to provide an error signal which can be used to recalibrate the measurement.
