Risk of foreign bodies in pipelines: the presence of dirt in the fluid may obstruct transfer channels, block the flow or
pressure sensor and impair correct system operation. Take care to install the sensors so that they are not subject to
the build-up of excessive sediment or air bubbles that may impair operation. If the size of the pipeline enables transit of foreign
bodies, a special filter may need to be installed.

Connection of sensors

The ends for connecting the sensors are in the centre and are accessible by removing the screw of the connections cover, see
Figure 3. The sensors must be connected to the relative inputs marked "Press" and "Flow"; see Figure 7.
