Abstract: In an ice maker, a controller is operatively connected to the ice maker's water system to determine a parameter indicative of a total amount of water filtered by a replaceable filter cartridge. Based on the determined parameter, the controller can provide a numerical indication of the total amount of water filtered by the replaceable filter cartridge. Based on the determined parameter, the controller can determine that the replaceable filter cartridge requires replacement. The parameter can be determined based on the amount of time a water inlet valve is opened and/or a water pressure signal. The controller can take action when it determines that the water filter needs replacement, for example, by making a local alarm indication, pushing a remote notification, or making an automated purchase transaction for a new filter cartridge.

Abstract: The following summary of the invention refers to the development of a multiple filtering device composed of three filtering elements (01 to 03) that are concentrically mounted on the lid (09) in the sequence EF1 (01), EF2 (02) and EF3 (03) with mesh measurements of different microns, forming four filtering chambers, with the purpose of retaining solids from agricultural spraying mixtures, monitoring the restrictive framework of the filtering elements through pressure switches (69.2) and pressure transducers (77) and alerting the obstruction through audio visual signaling (83, 83) so that the operator knows the exact moment to clean the multiple filtering device.

Abstract: A method of filtering water in a system comprising a regenerative media filter is disclosed. The method includes operating the system in a filtration mode, operating the system in a cleaning mode responsive to a differential pressure measurement across the regenerative media filter, and operating the system in a pre-filtration mode after operating the system in the cleaning mode. A water filtration system is also disclosed. The water filtration system includes a regenerative media filter vessel, a pressure sensor subsystem, a filtrate line, a feed line, a recirculation line, a plurality of valves, at least one pump, and a controller. The controller is configured to direct the water through the system. A method of facilitating filtration of aquatic or recreational facilities water is also disclosed. The method includes providing a water filtration system and providing a controller.

Abstract: A method for evaluating a service interval for replacing a filter of a system for extracting an aqueous liquid from a motor vehicle tank in response to the risk of progressive clogging of said filter from use. A compound clogging risk decision value (K) is generated (320) on the basis of the sum of a plurality of elementary values (k1, k2, k3, k4) of the clogging risk, each related to a risk criterion depending on the operation of the extraction system since commissioning of the filter. The compound clogging risk decision value is compared (340) to a threshold value, and an alert to replace the filtration device is generated (351, 352) if the compound clogging risk value exceeds the threshold value.

Abstract: Embodiments herein relate to fuel monitoring systems and related methods. In an embodiment, a fuel monitoring system for a vehicle is included having a fuel filter sensor device configured to generate data reflecting a filter restriction value of a fuel filter, a geolocation circuit configured to generate or receive geolocation data, and a system control circuit configured to evaluate the sensor data to determine changes in the filter restriction value. The control circuit can receive fuel level data, cross-reference geolocation data and fuel level data to identify refueling locations utilized, and correlate refueling locations with subsequent changes in filter restriction to identify an effect of specific refueling locations on fuel filter loading. In some embodiments, a refueling guidance system for a vehicle is included that can provide route and/or refueling site recommendations based on fuel filter loading rate data. Other embodiments are also included herein.

Abstract: An impending bypass switch includes a housing having a fluid inlet for admitting fluid into an interior of the housing. A piston is displaceable in the interior of the housing in response to a pressure variation of the fluid in the interior. A magnetic sensor is configured to receive a current and is fixedly mounted to the housing. A magnet is mounted to the piston to be displaced with the piston. Displacement of the magnet relative to the magnetic sensor causes a change in the current through the magnetic sensor. The change in the current is indicative of an impending bypass of a component.
