Abstract：Observational data during 2007-2011 with water tube meter at Malingshan seismic station is assessed in quality. The results show that: observational data are continuous; the conditions of instrument are stable;annual zero drift and change amplitude are small; they can meet the specification for deformation observation;primary wave tidal parameters is stable, observation accuracy (mγ) is about 0.004 5 from 2007 to 2010, which is less than 0.02; noise level ( M1) is less than 0.02 angle seconds, which met or surpassed the standard of outstanding deformation stations of China Earthquake Administration.
