ʻO ka hoʻolauna ʻana i ka mīkini kahe mākēneki

ʻO ka electromagnetic flowmeter kahi ʻano mika induction i hana ʻia e like me ke kānāwai o Faraday o ka electromagnetic induction e ana i ka kahe o ka leo conductive i loko o ka paipu.I nā makahiki 1970 a me 1980, ua hana nui ke kahe electromagnetic i ka ʻenehana, e lilo ia i ʻano mea hoʻohana ākea, a ke piʻi nei ka pākēneka o kona hoʻohana ʻana i ka mika kahe.

Nānā o ka noi:

Hoʻohana nui ʻia ka flowmeter electromagnetic ma ke kahua o nā mika anawaena nui i hoʻohana ʻia i ka hoʻolako wai a me ka ʻenekini hoʻoheheʻe;Hoʻohana pinepine ʻia ka liʻiliʻi liʻiliʻi a me ka liʻiliʻi i nā koi kiʻekiʻe a paʻakikī paha e ana i nā manawa, e like me ka hao a me ka ʻoihana kila i ka umu hoʻoluʻu wai hoʻoluʻu wai, ʻoihana pepa ana pepa slurry a me ka wai ʻeleʻele, ʻoihana kemika ikaika corrosion wai, pulp o nonferrous metallurgy ʻoihana. ;Hoʻohana pinepine ʻia ka liʻiliʻi liʻiliʻi, ka liʻiliʻi liʻiliʻi i ka ʻoihana lāʻau lapaʻau, ʻoihana meaʻai, biochemistry a me nā wahi ʻē aʻe me nā koi olakino.

Pono:

1. Kaila ana he paipu pololei lauwili, ʻaʻole e ālai ʻia, a kūpono no ke ana ʻana i ka wai paʻa paʻa ʻelua i loko o nā ʻāpana paʻa, e like me ka pulp, ka lepo, ka lepo, etc.

2. ʻAʻole ia e hoʻopuka i ka poho puʻe ma muli o ka ʻike kahe ʻana, a loaʻa ka hopena hoʻopakele ikehu maikaʻi;

3. ʻAʻole i hoʻopilikia nui ʻia ka nui o ke kahe kahe ʻana e ka hoʻololi ʻana i ka nui o ka wai, viscosity, wela, kaomi a me ka conductivity;

4. ka laulā kahe nui, ka laulā ākea;

5. Hiki ke hoʻohana i nā wai ʻino.

Nā hemahema:

1. ʻAʻole hiki ke ana i ka conductivity haʻahaʻa loa o ka wai, e like me nā huahana petroleum, wai maʻemaʻe, etc.;

2. ʻaʻole hiki ke ana i nā kinoea, nā mahu a me nā wai me nā ʻōhū nui;

3. ʻaʻole hiki ke hoʻohana i nā mahana kiʻekiʻe.
