Meter electronics (20) and method for obtaining a flow fluid viscosity at a predetermined reference temperature are provided. The meter electronics (20) includes an interface (201) configured to exchange communications, a storage system (204) configured to store a predetermined reference temperature (211), a measured fluid viscosity (214), a measured fluid temperature (215), and a temperature-viscosity relational data (218) that relates temperature to viscosity over a predetermined range of flow fluid temperatures, and a processing system (203) coupled to the interface (201) and to the storage system (204), with the processing system (203) configured to obtain the measured fluid temperature (215), obtain the measured fluid viscosity (214), and generate a reference temperature viscosity (227) using the measured fluid viscosity (214) and the temperature-viscosity relational data (218), with the generated reference temperature viscosity (227) corresponding to the predetermined reference temperature (211).
