SPIRAL FILM ELEMENT, SPIRAL FILM-FILTRATION DEVICE HAVING THE FILM ELEMENT, AND FILM-FILTRATION DEVICE MANAGING SYSTEM AND FILM-FILTRATION DEVICE MANAGING METHOD USING THE DEVICE

摘要

Provided are a spiral film element capable of securing more electric power without any complicated work, a spiral film-filtration device having the element, and a film-filtration device managing system and a film-filtration device managing method using the device. The spiral film-filtration device comprises a sensor (such as a flow rate sensor (32)) for detecting the properties of a liquid, a power-generating unit (such as a coil (25)) for generating an electric power with the liquid, and a radio-transmission unit (a communication unit (36)) supplied with the electric power from the power-generating unit for radio-transmitting a detected signal from the sensor. As a result, the power-generating unit generates the electric power by using the liquid (such as raw water, filtered water or condensed water) detected by the sensor, so that more electric power can be secured without any complicated work. The electric power from the power-generating unit is supplied to at least the radio-transmission unit, and the detected signal of the sensor is radio-transmitted from the radio-transmission unit.
