He aha nā ʻano o nā mika kahe wai hāmama a mākou e hoʻolako ai?

1. UOL ala hāmama kahe mika no nā ʻano like ʻole a me ka weir

Hiki ke ana pololei ʻia kēia mika e ke kiʻekiʻe o ka wai.Ke hoʻohana ʻia i ke ana kahe no ke kahawai hāmama, pono ia e hoʻokomo i ka flume a me ka weir.Hiki i ka weir ke hoʻololi i ke kahe i ke kiʻekiʻe o ka pae wai o ke kahawai hāmama. ʻO ka mika ke ana i ka pae wai i loko o ke awāwa wai, a laila helu i ke kahe kahe e like me ka pilina wai-kahe o ka awāwa wai e pili ana i ka microprocessor. i loko o ka mika.ʻO nā puʻupuʻu nui ʻo Bacher grooves, triangular weir a me rectangular weir.Ke ana ʻana i ka pae wai, hoʻohana ʻia ka ʻenehana kani kani ultrasonic, a hoʻopaʻa ʻia ka pae kiʻekiʻe ma luna o ka pae nānā wai o ka weir.Hoʻopili ʻia ka mokulele transmitter o ka ana pae kiʻekiʻe me ka ʻili wai.Ma lalo o ka mana o ka microcomputer, hoʻouna a loaʻa i ka mīkini kani kani ultrasonic.Wahi a Hb=CT/2 (ʻo C ka wikiwiki kani o ka hawewe kani ultrasonic i ka lewa, ʻo T ka manawa o ka hawewe kani ultrasonic i ka lewa), ua helu ʻia ka mamao Hb ma waena o ka mīkini pae kani ultrasonic a me ka pae wai i ana ʻia. e loaa ke kiekie o ka wai Ha.ʻO ka hope loa, loaʻa ke kahe wai e like me ke ʻano helu helu kahe.Ma muli o ke ana hoʻopili ʻole, hiki ke hoʻohana ʻia i nā wahi ʻino.He kūpono ka mīkini kahe kahe wai no nā loko wai, nā muliwai, nā papahana mālama wai, nā kahawai wai hoʻoheheʻe ʻia o ke kūlanakauhale, nā mea kanu wela e hoʻoheheʻe ana i nā kahawai wai kahawai, ka mālama ʻana i ka wai i loko a me ka hoʻokuʻu ʻana i nā kahawai, nā kūlana hana o ka hoʻokuʻu ʻana i ka wai ʻino a me nā papahana mālama wai a me ka wai mahiʻai. nā kahawai.

2. DOF6000 serial Area velocty open channel flowmeter no ke kahawai a i ʻole ka paipu piha piha

Hoʻohui ka mīkini kahe kahe o ka wahi i ka wikiwiki o ke kahe a me ke ana pae wai, hoʻohana ia i ke kumu Doppler ultrasonic no ke ana ʻana o ka kahe.Ke ana ʻana i ka pae wai, kau ʻia ka mea ʻike ma lalo a kokoke paha i kahi wai.Ma o ka hydrostatic pressure sensor, ua loaʻa i ke kaula uila ka mana o ka ea.Hoʻohana ʻia ke kaomi lewa ma ka ʻili wai e like me ke kaomi kuhikuhi o ka mea ʻike kaomi hydrostatic e ana i ke kaomi wai, i mea e helu ai i ke kiʻekiʻe o ka pae wai.He kūpono ka ʻāpana-velocity ultrasonic flowmeter no ke ana ʻana i nā kahawai hāmama a i ʻole nā ​​paipu piha ʻole me nā diameters ʻoi aku ka nui ma mua o 300mm no ka hoʻokuʻu ʻana i ka wai a me ka wai ʻino, nā kahawai maʻemaʻe, ka wai inu a me ka wai kai.
