A flow meter 110 adapted for calculating the flow rate of an injection fluid flowing through a subsea pipe into a well head on the sea floor, uses a flow parameter and a measurement of differential pressure in a specified flow model to determine the rate of fluid flow through the pipe; and, sends the determined rate of fluid flow from the subsea flow meter, via a communications interface, to a remote device. The parameter is determined based on a polynomial function of hydrostatic pressure and/or temperature of the fluid in the pipe, and the polynomial model comprises a plurality of coefficients. The processor of the flow meter is configured to receive a coefficient via the communications interface from a remote device, and to update the polynomial model to include the received coefficient. |
