LJS – 1780 Mea Kahe Wai

LJS – 1780 Kahe wai maʻamau Mea Kiʻi Hōʻike ʻia
  • LJS – 1780 Mea Kahe Wai

ʻO ka wehewehe pōkole:

ʻO ka Water Flow Standard Divice kahi mīkini metrological maʻamau no ka traceability, ka hoʻouna ʻana, a me ka hoʻāʻo ʻana i nā waiwai ana no nā lako kahe wai. Ke hoʻohana nei kēia mea hana i nā unahi uila a me nā mika kahe maʻamau ma ke ʻano he mau mea kuhikuhi, me ka wai maʻemaʻe e like me ke ʻano, e calibrate a hōʻoia i nā mika kahe like ʻole. He kūpono ia no ke ana ʻana o ke kahe naʻauao ma ka noiʻi hoʻokolohua, nā keʻena kiaʻi metrological, a me nā ʻāpana hana mīkini kahe.

Hoʻokumu ʻia ka hāmeʻa me kahi ʻōnaehana maʻamau metrological (mea hana maʻamau), kahi mālama wai kahe a me ka ʻōnaehana hoʻopaʻa paʻa, kahi hōʻoia a me ka ʻōnaehana hoʻāʻo (pipeline hōʻoia), nā pipelines kaʻina, nā mea ana ana, kahi ʻōnaehana hoʻoponopono kahe, kahi ʻōnaehana mana kamepiula (me ka loaʻa ʻana o ka ʻikepili, ka hana a me ka ʻōnaehana hoʻokele), kahi ʻōnaehana mana a me ka ea, nā ʻāpana maʻamau a me nā ʻāpana paipu, etc.
