The present disclosure relates to a filter system and a method for monitoring a vehicle condition using the same. The filter system according to an embodiment of the present disclosure includes a sensing apparatus installed at an exterior surface of a housing of a filter having a bypass valve, and configured to sense the condition of the filter, wherein the sensing apparatus is configured to include a hole sensor for sensing magnetic force caused by a location of a bypass valve lid, and a communication unit for transmitting measurement data of the hole sensor to outside.

A liquid filter for water separation and/or particle filtration of a fuel and/or aqueous solution, in particular a urea solution, and/or water, in particular in a motor vehicle, is described. The liquid filter has at least one filter and/or coalescer medium that is made of a non-woven fabric that has fibers and/or threads having elementary silver.

According to one embodiment, there is provided a chemical liquid supply system including a chemical liquid supply apparatus and a monitoring apparatus. The chemical liquid supply apparatus includes a nozzle, a filter, a first pressure gauge, and a second pressure gauge. The first and the second pressure gauge are disposed on the pipeline, respectively at a chemical liquid supply-source side and chemical liquid delivery side of the filter. The monitoring apparatus is configured to determine a state of the filter based on first differential pressure time information in which a differential pressure is acquired in a period until a time point of a lapse of a predetermined time since a start of pneumatic feeding of the chemical liquid to the nozzle. The differential pressure is a difference between a first pressure value measured by the first pressure gauge and a second pressure value measured by the second pressure gauge.

A filter monitoring system and method are described. The filter monitoring system includes a remote telematics system, and a data link between the remote telematics system and an onboard telematics system. The remote telematics system is configured to receive, via the data link, an indication of a pressure drop across a filter cartridge of the filtration system from the onboard telematics system, determine a first value indicative of a remaining filter life of the filter cartridge of the filtration system, determine a second value indicative of a remaining filter life of the filter cartridge that is determined in a different manner than the first value, compare the first value to the second value to determine which value indicates a least amount of life remaining for the filter cartridge, and transmit an indication of the least amount of life remaining for the filter cartridge based on the comparison.

A liquid chromatography monitoring system comprises a computer or electronic controller comprising computer-readable instructions operable to: (a) draw a fluid into a syringe pump; (b) configure a valve so as to fluidically couple the pump to either a fluidic pathway through a fluidic system or to a plug that prevents fluid flow; (c) cause the syringe pump to progressively compress the fluid therein or expel the fluid to the fluidic pathway, while measuring a pressure of the fluid; (d) determine a profile of the variation of the measured pressure; (e) compare the determined profile to an expected profile that depends upon the fluid; and (f) provide a notification of a sub-optimal operating condition or malfunction if the determined profile varies from the expected profile by greater than a predetermined tolerance.
