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.

A filter assembly includes a manifold having an inlet and outlet port. The filter assembly further includes a filter cartridge. The filter cartridge includes a casing and a filter casing disposed within the casing. The filter cartridge also includes a gear rack, and an inlet and outlet port. The filter assembly further includes an electric motor configured to move the filter cartridge along an axial direction by rotating a gear coupled to the electric motor such that the gear meshes with the gear rack. The filter cartridge is movable between a first position in which the filter cartridge and manifold are not in fluid communication, and a second position in which the filter cartridge and the manifold are in fluid communication. A refrigerator appliance having the filter assembly is also provided.

A performance indication device for a filter is provided. The performance indication device includes a water metering device to convert the energy of water flowing through the filter into mechanical rotation of a drive gear. A gear reduction assembly operably couples the drive gear to a valve gear and reduces the rotational speed of the valve gear relative to the drive gear. A flow controlling device is operably coupled to the valve gear and is configured to reduce or terminate the flow of water through the performance indication device and the filter when a target flow capacity is reached. The performance indication device thus provides an accurate indication to the user as to when the filter capacity has been expended without the need for a complex control system or communication link or any modification of the appliance in which the filter is installed.

A health meter with decontamination device for contaminated fluid with a metal casing body with sealable metal lid, inlet port and outlet port, a removable open bucket having a docking lid and a plurality of openings, a hollow tube with an opening connected to an outlet port, a convex reinforcing spacer in the removable open bucket, a compressible decontamination media and a reinforcing seat in the removable open bucket. Contaminated fluid flows into the metal casing body between the removable open bucket and metal casing body through openings in the docking lid into the compressible decontamination media sequentially into the hollow tube and out the outlet port while an inlet and outlet electrode and two sensors in the media communicate with a controller via a network to a plurality of client devices for automatic remote monitoring.

A machine, a filtration system and a method for disinfection and purification in fuel tanks located in places with high humidity or high relative humidity, having a machine (1) with an inlet for the fuel from the tank, a filtration system of a coarse-grain filter (2) and a fine-grain filter (2′); a radiation chamber (3) configurable for the application of radiation to the filtered fuel; a pump (4); a flowmeter (5) with at least two electrovalves (17); a centrifuge (6) with a turbine filter (6′) and control via an electrical panel (7); a cleaning machine (1); a suction hose (8) with an extendable suction lance (9); a high-pressure discharge hose (11); a return hose (12); a system for the opening and sealing of the tank (25); and an automatic filter self-cleaning system which reverses the flow, sending the fouled fuel to an additional tank (14) where it is drained.

A fuel filter monitoring method includes receiving pressure signals that are indicative of a pressure drop across at least one fuel filter of a fuel supply system configured to supply fuel to at least one fuel injector of an internal combustion engine and receiving a condition signal indicative of a condition of a fuel supply system, the condition signal being generated by one or more of a geographic location sensor, an altitude sensor, and/or a fuel temperature sensor. The method includes estimating a remaining life of at least one fuel filter of the fuel supply system based on the pressure signal and the condition signal and outputting a notification indicative of the estimated remaining life.

An arrangement and method for determining the service interval of a fluid filter includes a filter and a pump driven by an electric motor. A control module calculates pressure drop across the filter by way of voltage, current, and/or PWM provided to the electric motor. The control module monitors the rate of change of the pressure drop across the filter over the life of the filter. The volume flow rate of the fluid may or may not be held constant. If an abrupt or sudden characteristic change in the pressure drop across the filter occurs, or if the pressure drop across the filter exceeds a threshold amount, the arrangement and method provides a notification that either the filter needs to be replaced or serviced, or that it is probable that a mechanical condition has developed, depending upon the characteristics of the change in pressure drop across the filter.
