In view of the operation condition of the instrument and the factors in the external environment that influence observation quality,and the different characteristic of the geological structure of different stations,we used the observation data of DSQ tube tiltmeters in Wujiahe,Baotou and Wuhai seismic stations on the northern edge of the Ordos massif from 2015 to 2017. We compared the characteristic parameters such as annual zero drift,relative noise level,M₁,M2 wave tidal factor,and carried out co-seismic response analysis. The research shows that the observation quality of the water tube tiltmeter of Baotou seismic station is better than that on the other stations,which mainly reflects in small zero drift,high precision and stability. It provides a scientific reference for the evaluation of the efficiency of the water tube tiltmeter. The delay time of co-seismic response is related to the epicentral distance,and the maximum amplitude is positively correlated with the magnitude and negatively correlated with the epicentral distance.
