A filter for treating a fluid in a piping, in particular a piping included in a water supply network, includes: a main body having at least one internal chamber and a filtering element for treating the fluid, the filtering element having at least one magnetic element housed at least partially in the chamber and adapted to intercept and trap the ferrous impurities that are present in the fluid to be treated. At least one magnetic detector is associated with the main body for detecting the magnetic field generated by the at least one magnetic element. A control unit is associated with the at least one magnetic detector, the control unit being adapted to process the magnetic field information received from the at least one magnetic detector and to provide an indication about the quantity of impurities that have accumulated on the filtering element.

A wire harness assembly including a first connector, a second connector, and conductors extending between the first connector and the second connector. Contacts are provided on the second connector. The contacts have termination sections which are mounted on the second connector, compliant sections which extend from the termination sections, and substrate engagement sections which extend from the compliant sections. The substrate engagement sections have curved contact sections which are configured to be positioned in mechanical and electrical engagement with circuit pads of a mating printed circuit board. Embossments are provided on the curved contact sections to provide additional strength and stability to the curved contact sections.

A filtering apparatus (100) having a filtering mode and a self-cleaning mode, the apparatus provided for filtering an upstream flowing fluid with filtering elements (20) in the form of a plurality of stackable discs during filtering mode utilizing a first flow direction, apparatus (100) also configured to self-clean the filtering elements (20) the apparatus (100) including an internal fluid diverter (110,210, 310) that is internal to the filter housing. The position of the internal fluid diverter determines the direction of fluid flow through the filter housing and the filter phase. The position of the internal fluid diverter is controlled with a controller disposed external to the filter housing that may be manipulated either manually or by automated means.

A disposable filter including an integrated sensor is provided for filtering a working fluid and monitoring the working fluid and/or the performance of the filter. The filter includes a housing with an inlet and an outlet with filter media disposed within the housing in a flow path defined between the inlet and the outlet. The integrated sensor is disposed within the housing, where the integrated sensor monitors a characteristic of the working fluid or other performance characteristic of the filter. The sensor assembly may include a communication module. The sensor assembly may include a RF tank circuit with a capacitor plate, which may be disposed adjacent a bypass structure that is disposed adjacent the outlet. Movement of a moveable part of the bypass structure in response to a pressure buildup will cause a shift in a resonant frequency of the tank circuit.

An apparatus includes a chemical filter fluidly coupled between a source for a processing solution and a nozzle to dispense the processing solution. The chemical filter is configured to filter the processing solution from the source. The apparatus may include a vacuum pump that is configured to apply a vacuum to the chemical filter. The apparatus may include a valve system configured to operate in a first operating state and a second operating state, where in the first operating state the valve system is configured to couple the source to the chemical filter and block the vacuum to the chemical filter, and where in the second operating state the valve system is configured to couple the vacuum to the chemical filter and block the source to the chemical filter.

A method is disclosed for maintaining a filtration device of a system for extracting a liquid from a tank of a motor vehicle. The method is based on risk criteria for detecting (301) the choking of the device and on application criteria for identifying (302) a context favorable to the cleaning of the filtration device. The cleaning of the filtration device, based on generating (303) a reverse stream in the extraction system, is thus only triggered when specific, configurable conditions are identified.

A monitoring assembly includes a diverter, a fluid delivery network, an analysis subsystem, and a pump. The diverter be configured to fluidly couple to a single port of a process pipe. The network can be configured to receive a process fluid including an incumbent additive from the diverter. The analysis subsystem can be configured to receive the process fluid from the network, to measure a predetermined property of the received process fluid within a sensing chamber, and to output a signal representing the measured property. The pump can be configured to urge the process fluid from the analysis subsystem to the diverter via the network. The assembly can also include a conditioning subsystem configured to treat the process fluid with a process additive prior to measurement. The assembly can further include a filtration subsystem configured to filter the process fluid prior to measurement.
