Installation of the flow sensor
• Installation can occur in horizontal and vertical pipes. In horizontal pipes the sensor should be installed in a
horizontal position to ensure that the measuring electrodes are always wetted by the medium. The flow
sensor is only suitable for application in completely filled pipe systems.
• As a matter of principle magnetic inductive flow sensors are widely independent from the flow profile. An inlet
section is not absolutely necessary.
To reach the desired accuracy of the measurement, straight inlet and outlet sections according to the
nominal pipe size (NPS) should be used. The inlet section has to be at least 10 x NPS and the outlet section
5 x NPS in order to achieve the specified accuracy.

• The inlet and outlet sections and the gaskets must have the same or a slightly larger inside diameter than the
measuring tube in order to achieve the specified accuracy.
• When tightening screw connections always grip the hexagon nut (see Fig. 4).
