  • Clogging estimation method and filter monitoring system
    Patent number: 10500528
    Abstract: The ability to estimate a filter clog by a means other than measuring fluid pressure is presented. The filter monitoring system of the present disclosure comprises a vibration data transmission unit, which is mounted on a filtration device, detecting filter vibrations associated with the operation of filtration device described above, sending such as vibration data, and a clog estimation unit, which detects the phenomenon of declining vibration value caused by a filter clog, estimating the degree of blockage for the filter described above.
    Type: Grant
