  • Flowmeter
    Patent number: 4784193
    Abstract: A magnetically inductive flow meter having a measuring tube is positioned in a pipe line for measuring the flow of a fluid product in the pipe line for enabling control of a control element. The flow meter is aligned between a control element positioned in the pipe line, which is for influencing the flow of fluid product, and a drive unit associated with the pipe line, which is for actuating the control unit for influencing the fluid product flow. A mechanically displaceable actuating rod connected with the drive unit extends into the pipe line and extends axially through the measuring tube to a connection with the control element for actuating the control element by means of the drive unit.
