Farqiga saxda ah ee u dhexeeya mitirrada socodka ultrasonic-ka ee hal-waddo iyo kuwa badan-waddo ma ballaarin doonaa iyadoo isbeddelka heerka socodka uu dhacayo marka la cabbirayo dhuumaha dhexroorka weyn (tusaale ahaan, DN1000 iyo wixii ka sarreeya)?

Haa. Mitirayaasha socodka ultrasonic-ka ee hal-waddo ah waxay caadi ahaan cabbiraan xawaaraha socodka ee bartamaha dhuumaha ka dibna waxay u beddelaan xawaaraha socodka celceliska ee isgoyska dhuumaha iyagoo adeegsanaya "celceliska xawaaraha isku-dhafka ah." Isku-dhafkan wuxuu ku salaysan yahay mala-awaalka "socodka si buuxda loo horumariyay" (halkaas oo xawaaraha uu raaco qaybinta logarithmic). Si kastaba ha ahaatee, dhuumaha dhexroorka weyn, marka heerka socodka uu hooseeyo (xaaladaha laminar ama jahwareerka hooseeya oo leh lambar Reynolds < 2300), qaybinta xawaaraha waxay u dhowdahay qaab parabolic ah. Natiijo ahaan, qaladka beddelka ee mitirrada hal-waddo ah (laga bilaabo xawaaraha dhexe ilaa xawaaraha celceliska) wuxuu ka fidaa ±1% ilaa in ka badan ±3%.
