Abstract Comparative analysis of the observation data of VS vertical pendulum and DSQ water pipe inclinometer from 2015 to 2022 at Macheng station is conducted. The results show that: 1) The tidal observation data is continuous and reliable, the instrument works normally and stably, and the quality of data and the accuracy of tidal factor are at the leading level in China. 2) The data of VS vertical pendulum is more stable and has a low failure rate. 3) In terms of coseismic response, the sensitivity of DSQ water pipe inclinometer is higher than that of VS vertical pendulums, and the DSQ water pipe inclinometer can clearly record seismic events over M5.5 and epicentral distance within 1 500 km.
