ʻO ka vortex flowmeterua hoʻokumu ʻia ma ke kumu Karman vortex. Hōʻike nui ʻia ʻo ia ma ke ʻano he mea hoʻoheheʻe vortex non-streamline (bluff body) i hoʻonohonoho ʻia i loko o ka wai kahe, a ʻelua lālani o nā vortex maʻamau e hana ʻia mai nā ʻaoʻao ʻelua o ka mea hana vortex. Hoʻohana nui ʻia ia i ka petroleum, chemical, metallurgical, thermal, textile, pepa a me nā ʻoihana ʻē aʻe no ka superheated steam, saturated steam, compressed air and general gases (oxygen, nitrogen, hydrogen, natural gas, coal gas, etc.), wai a nā wai (e like me ka wai, gasoline, etc.) , Alcohol, benzene, etc.) ana a me ka mana.
ʻO ka maʻamau, liʻiliʻi ke kahe o ka pipeline biogas, a ke ana ʻia ma ka hoʻemi ʻana i ke anawaena. Hiki iā mākou ke koho i ʻelua ʻano hana, ʻano kāleka flange a me ke ʻano flange. I ke koho ʻana i ke ʻano, pono mākou e koho e hoʻomaopopo i ke kahe kahe liʻiliʻi, ka kahe kahe maʻamau a me ka nui o ke kahe o ka biogas. ʻAʻohe kumu mana o ka hapa nui o nā wahi ana biogas, no laila hiki iā mākou ke koho i nā kahe kahe vortex i hoʻohana ʻia i ka pākaukau. Inā pono ka mea hoʻohana e hoʻolauna i ka hōʻike o ka mika i loko o ka hale, hiki ke hoʻohana ʻia kahi flowmeter vortex i hoʻohui ʻia, a alakaʻi ʻia ka hōʻailona puka i ka totalizer kahe i hoʻokomo ʻia i loko o ka lumi ma o ke kaula. Hiki i ka vortex flowmeter ke hōʻike i ke kahe koke a me ke kahe kumulative o ka biogas.
Ke kau ʻana i kahi vortex flowmeter e ana i ka biogas, inā hoʻokomo ʻia kahi valve kokoke i ka upstream o ka wahi hoʻonohonoho, a wehe mau ʻia ka pahu a pani ʻia, e loaʻa ka hopena nui i ke ola lawelawe o ka ʻike. He mea maʻalahi loa ia e hana i ka pōʻino mau i ka sensor. E hōʻalo i ka hoʻokomo ʻana ma luna o nā paipu lōʻihi loa. Ma hope o ka lōʻihi o ka manawa, e maʻalahi ka sagging o ka sensor i ka leakage sealing ma waena o ka sensor a me ka flange. Inā pono ʻoe e hoʻokomo iā ia, pono ʻoe e hoʻokomo i ka pipeline ma ka upstream a me lalo o 2D o ka sensor. Mea hoʻopaʻa.
No ka hōʻoia ʻana i ka hana holoʻokoʻa, ʻaʻole pono e hoʻopilikia ʻia ke ʻano kahe ma ka puka. ʻO ka lōʻihi o ka ʻāpana paipu pololei i uka ma kahi o 15 mau manawa o ke anawaena flowmeter (D), a ʻo ka lōʻihi o ka ʻāpana paipu pololei i lalo ma kahi o 5 mau manawa o ke anawaena flowmeter (D). Ke hoʻonoho ʻia kahi mea kani vortex non-streamline i loko o ka wai, e hana ʻia nā lālani ʻelua o nā vortex maʻamau mai nā ʻaoʻao ʻelua o ka vortex. Kapa ʻia kēia vortex ke alanui Karman vortex. I kekahi pae kahe, ua like ka vortex separation frequency i ka awelika kahe kahe o ka pipeline. Hoʻokomo ʻia ka capacitance probe a i ʻole piezoelectric probe (detector) i ka vortex generator a ua hoʻonohonoho ʻia ke kaapuni pili e hana i kahi ʻike capacitance.
vortex flowmetera i ʻole Piezoelectric detection type vortex flow sensor.
