A LOW-COST ELECTROLYTIC TILTMETER FOR MEASURING SLOPE DEFORMATION

The tiltmeter described consists of an electrolytic sensor (a glass jar containing an electrolyte and six electrodes) and a portable AC digital conductivity meter, which reads conductivity changes resulting from tilting deflections. The tiltmeter has a sensitivity of 2 to 8 min of arc/cmu (conductivity meter unit), with a measurement range of more than 45 deg. This tiltmeter measured earth flow subsurface movements reliably. It was easy to install and read.
