  • Method and device for supplying a measurement electronics system with electrical energy
    Patent number: 9748818
    Abstract: A method and a device for supplying a measurement electronics system in a fitting, through which a fluid flows, with electrical energy, which is generated in a turbine by the fluid flowing through the filling, wherein the flow quantities and pressures vary within wide boundaries, typically 1:1000. A pressure control device associated with the turbine controls the pressure of the fluid striking the turbine in such a manner that the electrical energy required for operating the measurement electronics system is generated with a small flow quantity, the pressure loss incurred by the fluid while flowing through the fitting being limited to a maximum value.
    Type: Grant

    Inventors: Burghard Schaefer, Volker Keller, Tuan Chu Anh
  • Measurement apparatus for measuring the throughflow of a fluid
    Patent number: 9389110
    Abstract: A measurement apparatus having a measurement tube and a thermal sensor for measuring a throughflow of a fluid flowing through the measurement tube, the measurement tube having an inlet and an outlet, and also a measurement section, in which the sensor is arranged. The inlet has an inlet internal diameter and the measurement section has a measurement section internal diameter, and whereby the measurement section internal diameter is greater than the inlet internal diameter.
