Maintenance-free, regardless of heavy deposits

In pump shafts, the deployed mea­sure­ment tech­nol­o­gy has to con­tend with mate­r­i­al that can quick­ly influ­ence the mea­sur­ing results. In Zeu­len­ro­da, mea­sur­ing with a sus­pend­ed pres­sure trans­mit­ter through a pipe that reached down to about 10 cm above the ground was dif­fi­cult. Due to a pile of sand that formed at the bot­tom of the shaft, inac­cu­ra­cies kept occur­ring. To solve the prob­lem, employ­ees of the sewage treat­ment plant decid­ed to try radar mea­sure­ment with a VEGAPULS C 23 with encap­su­la­tion. The mea­sure­ment now takes place con­tact­less­ly at the upper rim of the shaft. From there, the radar sen­sors oper­ate with­out effect from dirt and buildup – or from “annoy­ing” sand accu­mu­la­tions. In Zeu­len­ro­da, VEGAPULS C 23 proves that it’s pos­si­ble to have a clear view despite all adver­si­ties: In any case, the sen­sor doesn’t care at all about accu­mu­la­tions of mate­r­i­al, no mat­ter what kind.
