<p>A multifunctional filter for waterworks, comprising a containing body (1) having at least a inlet (21) and an outlet (22) for liquid, at least a filter cartridge (40), sensors of pressure (34,35) and of flow rate (27,28,32a) arranged in the body (1), electronically programmable means (32) connected with an external device, such as a motor pump, for switching it on or off responsive to signals coming from the sensors. The body (1) can be formed by a head (20) having the inlet (21) and the outlet (22), a lid (30) that stops the head (20) and houses the electronically programmable means (32) and the sensors, a cartridge container (10) releasably fastened to the head (20) for pushing the filter cartridge (40) against the head, chambers of passage (23a,26,29) of the liquid flow to be filtered made in the head (20). The sensors can be integrated on a programmable board (32). The filter has the advantage of being compact, easily installed and substituting other devices not necessary any more, such as flow control or litre counting devices. <IMAGE></p> |
