Claim One:
1. A system for continuously monitoring performance of a rotary-type gas flow meter, the system comprising: a pressure sensor module for measuring a differential pressure (dP) of a gas flowing through the gas flow meter, the pressure sensing module having an output signal; a processor module; and a data store communicatively connected with the processor module, the data store storing instructions executable by the processor, wherein the instructions executable by the processor include instructions to calculate a coefficient during a learning phase period, the coefficient based on: a plurality of measured dP of the gas flowing through the gas flow meter during the learning phase period, a plurality of measured line pressures of the gas flowing through the gas flow meter during the learning phase period, a plurality of measured flow rates of the gas flowing through the gas flow meter during the learning phase period, a plurality of measured temperatures of the gas flowing through the gas flow meter during the learning phase period, and a specific gravity of a gas flowing through a gas flow meter during the learning phase period, and wherein the instructions executable by the processor include instructions to calculate a first dP at a first instance of time, the first dP at the first instance of time based on at least the coefficient.
