Claim:
1. A method for supplying a fluid flow rate electronic measuring system in a fitting on a pipe section, through which a fluid flows, with electric power, wherein a flow rate of the fluid flowing through the fitting fluctuates, via a power generating device, the method comprising: arranging a generator having a turbine in the pipe section through which the fluid flows, the generator and the fitting being arranged in series, and the generator generating electric power to supply the electronic measuring system, so that the electronic measuring system in the fitting has electric power to measure the flow rate of the fluid; providing a control device; and providing at least one element for influencing the fluid flow through the power generating device, wherein the turbine of the generator generates electric power starting at a predetermined minimum flow rate of the fluid through the fitting, wherein a pressure loss of the fluid that the fluid experiences in the power generating device is determined by measuring pressure at a position upstream of both the generator and the fitting and at a position downstream of both the generator and the fitting, and wherein the control device, depending on the determined pressure loss and/or the flow rate measured by the electronic measuring system in the fitting, controls the at least one element for influencing the fluid flow so that the pressure loss that the fluid in the power generating device experiences does not exceed a predetermined value.
