| Abstract;We designed a liquid-tube tiltmeter that is only half-filled with silicon oil. The tiltmeter consists of float and a pair of magnets in each sensing pot. The float has an iron fork at the bottom and a pair of magnets keeps the float at the center of the pot and prevents it from rotation. This instrument was installed next to a normal type water-tube tiltmeter and the results of the tidal analysis of the data from these two types of tilmeters are compared. The effects of atmospheric pressure have been shown to decrease remarkably in the half-filled type data. (author abst.) |
