C

5.5 Ground connection

The foot of the enclosure has two screw connection points (one M5 thread and one M4
thread) to attach a ground conductor. See the picture below.

Figure 5-5: Ground connection

This ground connection can be used to connect the upstream and downstream piping to the
Ultrasonic Flow Meter (Equipotential).
