Abstract (en)
[origin: WO2013189505A1] The invention relates to a method and a device for supplying a measurement electronics system (3) in a fitting (2), through which a fluid flows, with electrical energy, which is generated in a turbine (7) by the fluid flowing through the fitting (2), wherein the flow quantities and pressures vary within wide boundaries, typically 1:1000, wherein a pressure control device (5) associated with the turbine (7) controls the pressure of the fluid striking the turbine (7) in such a manner that the electrical energy required for operating the measurement electronics system (3) is generated with a small flow quantity, the pressure loss incurred by the fluid while flowing through the fitting (2) being limited to a maximum value.
