    Abstract: An internal combustion engine monitoring system can include a fluid filter disposed between at least one fluid inlet of the internal combustion engine and at least one of a fluid source or an ambient fluid environment. At least one fluid sensor arranged can be arranged to detect a plurality of indications of respective fluid pressures on first and second sides of the fluid filter at a plurality of corresponding engine operating conditions. The indications can be compared with their corresponding operating conditions to assess a condition of the fluid filter and estimate a lifetime thereof.

    Abstract: A contamination prompt structure for a filter medium may comprise a filter element and a prompt assembly. The prompt assembly may have a movable part. One end of the movable part may be in communication with one of a water inlet of the filter element, or a water outlet of the filter element, and the other end of the movable part may be in communication with the other one of the water inlet of the filter element, the water outlet of the filter element, or outside air. When the filter element is in a contaminated state, a rise of pressure at the water inlet or a drop of pressure at the water outlet may drive the movable part to move to send a prompt for a user to replace the filter element.

    Abstract: Embodiments of the disclosure provide a filtration assembly. The filtration assembly includes a fluid inlet, a fluid outlet, first and second flow lines positioned fluidly between the fluid inlet and the fluid outlet, a differential pressure sensor, and a controller. The first flow line includes a first canister filter, a first filter housing, and a first valve configured to move between a closed position and an open position. The second flow line includes a second canister filter, a second filter housing, and a second valve configured to move between a closed position and an open position. The controller is configured to receive, from the differential pressure sensor, a differential pressure value, and when the differential pressure value is greater than a threshold value, generate a signal to one of the first and second valves to close the respective valve.

    Abstract: A filter press (100) is described comprising: a plurality of filtration chambers (155) each of which is delimited by two mutually facing filtering septa (140, 145) interposed between a pair of containment plates (105), a movement apparatus adapted to move each pair of containment plates (105) between a closed configuration and an open configuration, an inlet hydraulic circuit of the liquid to be filtered, an outlet hydraulic circuit of the filtered liquid, and a washing robot (400) adapted to wash the filtering septa (140, 145) that delimit each filtration chamber (155), wherein said washing robot (400) comprises: a trolley (405) adapted to move along a longitudinal direction (A) with respect to the containment plates (105), a bar (445) installed on the trolley (405) and movable relative thereto in a transverse direction with respect to the longitudinal direction (A), and a plurality of nozzles (450) installed on said bar (445) to dispense jets of a washing liquid toward said filtering septa (140, 145), the filter press further comprising: a plurality of identification codes, each of which is fixed to at least one respective filtering septum (140, 145), a device for detecting said identification codes installed on the trolley (405) of the washing robot (400), at least one image acquisition device (600) installed on the bar (445) of the washing robot (400) to acquire images of said filtering septa (140, 145), and an electronic processing unit connected to the identification code detection device and to the image acquisition device (600).
