DP
  • erinevus staatiliste rõhkude vahel, mis on saadud mõõtmisel toruseina mõõtekohtade juures, millest üks asub ülesvoolu ja teine mõõtevahendist allavoolu poolel, sisestatuna sirgesse vootorusse, kui on arvesse võetud kõrguste erinevust üles- ja allavoolu rõhumõõtekohtade vahel
  • esmaseadme tekitatud rõhuerinevus, kui arvesse võetakse voo sisse- ja väljavoolu kohtades rõhuühenduste vahelist näiduerinevust
  • difference between the (static) pressures measured at the wall pressure tappings, one of which is on the upstream side and the other of which is on the downstream side of a primary device, inserted in a straight pipe through which flow occurs, when any difference in height between the upstream and downstream tappings has been taken into account
  • pressure difference generated by a primary device when any difference in datum level between the upstream and downstream pressure tappings is taken into account
rõhuvahe
Usage examples
  • Terminit „rõhuvahe“ kasutatakse ainult siis, kui rõhumõõtekohad on iga mõõtevahendi jaoks kindlaksmääratud asendites.
∆p symbol
differential pressure
Usage examples
  • The term “differential pressure” is used only if the pressure tappings are in the positions specified for each standard primary device.

  • difference between the pressure measured at the total anbd static pressure tappings of a Pitot static tube or between the total pressure measured at the pressure tapping of a total pressure Pitot tube and the static pressure measured at a conduit wall pressure tapping

Usage examples
  • Pitot' torude üldine tööpõhimõte tekitab rõhuvahe Pitot' torus.
