Mita Rere Wai Doppler Ringaringa 4-20mA e Whakahaeretia ana e te Pūhiko mō te Parakaingaki

Kua hangaia ngā mita rere ultrasonic Doppler hei ine i te rere rōrahi o te wai totoka, wai hau rānei i roto i te paipa kua kati. Me kī tonu te raina paipa i ngā wai me ētahi mirumiru hau, i ngā totoka iri rānei. Ka taea e tēnei te whakaatu i te tere rere me te tapeke rere, me ētahi atu. Waihoki, kua whirihorahia ki te 4-20mA, putanga OCT. He pai ngā mita rere ringaringa mō te rahi paipa mai i te 40mm-4000mm. Ka taea te mahi i ngā wāhi maha o te pāmahana mahi -20 ki te 60 ℃. He whānuitia te whakamahi i roto i ngā paipa kua kī tonu, pērā i te paru mata, te paru whakahohe, te wai whenua, te penupenu, te paru pepa/matū, te tukurua rerenga me te keri me ētahi atu.
