Intelligent detector for working state of filter membrane of fully-automatic filter device for environmental water sample

Moving the movable plate and the fixed plate composed of a variable capacitance, the movable piece; environmental water samples of the present invention means a filter membrane filtration automatic intelligent operation state detector, the flow detector hose three parts, consisting of the movable plate and the fixed plate is converted to a change in capacitance, and thus detected by the detection circuit of the variable capacitance changes in capacitance, the amount of water to the water hose segment can be determined and thus indirectly determines whether or not the clogging of the filter membrane.
