Hoʻohana ʻia kekahi ʻano transducers ʻelua (nā ʻike A a me B ma ke kiʻi ma lalo), e hoʻouna a loaʻa i nā hawewe kani ultrasonic.ʻOi aku ka wikiwiki o ka hele ʻana o ka hōʻailona i uka ma mua o ka upstream i loko o ka wai, a ʻo ka ʻokoʻa o ka manawa he zero i ka wā e noho mālie ai ka wai.No laila, ʻoiai ke ana ʻia ka manawa o ka hoʻolaha ʻana i lalo a me ka hoʻolaha kūʻē, hiki ke loaʻa ka waiwai ʻokoʻa △t.A laila, e like me ka pilina ma waena o △ T a me ka wikiwiki V, hiki ke ana ʻia ka awelika ka wikiwiki o ka waena, a hiki ke helu ʻia ka kahe o ka leo Q e like me ka ʻāpana cross-sectional.
V = K * △ t
Q=S×V, ma kahi o K he mea mau a o S ka mahele kea iloko o ka paipu.
ʻO ka transit-time ultrasonic flowmeter he kūpono ia no ke ana ʻana i ka wai maʻemaʻe ma kahi paipu piha i pani ʻia, a ʻo ka maʻiʻo o nā ʻāpana i hoʻokuʻu ʻia a i ʻole nā pua i loko o ka wai i ana ʻia ma lalo o 5.0%.Hiki ke hoʻohana nui ʻia kēia ʻano kahe kahe ma lalo o nā wai.
1) Ka wai paipu, ka wai kaapuni, ka wai hooluolu, ka wai wela, a pela aku;
2) Ka wai maka, ka wai kai, ka wai hoʻoheheʻe maʻamau, a i ʻole ka wai hoʻoheheʻe lua;
3) ʻO ka inu, ka waiʻona, ka pia, ka lāʻau lapaʻau wai, a pēlā aku;
4) Mea hoʻoheheʻe kemika, waiu, yogurt, etc.;
5) ka ʻaila, kerosene, diesel, a me nā huahana aila ʻē aʻe;
6) Mea kanu mana (nukelea, wela, a me ka hydraulic), wela, hoʻomehana, hoʻomehana;
7) ʻOhi kahe, ʻike leak;Kahe, ka hoʻokele quantization wela, ka ʻōnaehana pūnaewele nānā;
8) Metallurgy, mining, petroleum, ʻoihana kemika;
9) Ka nānā 'ana i ka ikehu a me ka mālama mālama wai;
10) Ka meaʻai a me ka lāʻau lapaʻau;
11) Ana wela a me ke kaulike wela;
12) Ma ka paena kahe kahe ana mika calibration, calibration, ʻikepili loiloi, etc.
