1. A method of analysing fluid flow, comprising:
- performing a first set of diagnostic checks associated with a first fluid flow meter of a first type which measures fluid flow according to a first physical principle, said first set of diagnostic checks including readings or calculations for validating a fluid flow rate measured by the first flow meter;
performing a second set of diagnostic checks associated with a second fluid flow meter of a second type which measures fluid flow according to a second physical principle, said second set of diagnostic checks including readings or calculations for validating a fluid flow rate measured by the second fluid flow meter; and
cross-referencing the first set of diagnostic checks and the second set of diagnostic checks to identify or provide additional information about a metering malfunction.
