capacitive sensors can be used to detect corrosion or leak. with one end of the capacitor open the dielectric material is exposed to the pipe. if any leakage occurs the liquid will change the capacitance of the capacitor and hence the flaw can be detected. but, of course, the dielectric should be porous. any idea of such dielectric material?
also, i would like to know of any potential flaw in this method of leak detection from you guyz.
