In thermal power plant's new-built unit debugging, the difference in height of differential pressure type level gauge positive and negative pressure side sampling pipe (upper and lower sampling pipe) is the value must used in measuring, and in actual Pipe installing, because the various factors such as design, construction may cause the inconsistent of difference in height and anticipation, actual measurement is needed to go out accurate value, to ensure the accuracy measured.In unit operation, the level gauging deviation caused because of various factors such as burning, thermal expansions also occurs now and then, and under hot operating mode, also likely needs the difference in height of demarcating differential pressure levelmeter positive and negative pressure side sampling pipe.Therefore, the accurate measurement of difference in height is a necessary guarantee during power plant normally runs.
In actual motion, because positive and negative pressure side sampling pipe is not generally accomplished just right up and down, therefore direct ruler is measured and cannot be obtained accurate difference in height, and now not relevant professional survey instrument.
In actual measurement, part power plant takes to measure with ruler, and following sampling pipe, as benchmark, with the naked eye estimates that ruler is to upright position, then estimates reading and upper sampling pipe level of approximation scale, thus obtains difference in height; Also have part power plant to adopt U-tube principle, measuring process often needs vertically regular column as the reference substance demarcated, but this condition is difficult to meet sometimes, and under hot operating mode, hose cannot cause the method not use close to pipeline.So generally the measurement of this value exists deviation to a certain degree, thus be in operation and can not obtain level value accurately always.
