  • Publication number: 20110224867
    Abstract: To reliably perform updating of maximum values and minimum values of measurement data with a simple procedure without incurring an increase in the computational load of an arithmetic processing element such as a microcomputer. When processing is started, a most recent maximum value stored in a nonvolatile storage element 4 is written to a maximum value-use variable Xmax and a positive maximum value is written to a minimum value-use variable Xmin (step S404), and each time temperature data are acquired, a value of acquired data Xk and a most recent minimum value Xmin are compared and the smaller value is set as a new minimum value Xmin (step S408), and each time updating of this minimum value is repeated a predetermined number of times of processing Ns, the minimum value Xmin at that point in time and the maximum value Xmax are compared and the larger value is set as a new maximum value Xmax, whereby updating is performed (steps S406 and S410).

    Abstract: Provided are a spiral type membrane filtering device by which an electric component can be re-used and a mounting member, as well as a membrane filtering device managing system and a membrane filtering device managing method using the same. An interconnector (42) attachable and detachable to a membrane element is provided with a sensor that detects the property of liquid such as raw water or permeated water that flows within a membrane filtering device, or a power generating section (26). Therefore, even if the membrane element is to be replaced, the sensor or the power generating section (26) can be re-used by re-mounting the interconnector 42 onto a new membrane element. Also, since there is no need to add a change to the membrane element, a conventional membrane element can be used as it is.
