Ultrasonic flowmeter a me electromagnetic flowmeter kēlā me kēia ʻano a me nā ʻokoʻa

ʻO ka mīkini kahe kani kani a me ka electromagnetic flowmeter nā mea hana maʻamau e ana i ke kahe ʻana o ka ʻoihana, ʻo kēlā me kēia mea he ʻano ʻano like ʻole a me nā kahua noi.

ʻO ka mīkini kahe kani kani ultrasonic:

Nā hiʻohiʻona:

1. Non-invasive, ʻaʻohe poho kaumaha;

2. Hoʻokomo maʻalahi, uku mālama haʻahaʻa;

3. ʻO ke ana ākea ākea, hiki ke ana i ka wela kiʻekiʻe, ka wai viscosity kiʻekiʻe a me ke kinoea;

4. He maʻalahi ka hoʻolālā ala kahe a kūpono i nā hiʻohiʻona like ʻole a me nā anawaena paipu.

ʻO ka ʻokoʻa:

1. Ana kumu: Hoʻohana ka ultrasonic flowmeter i ka ʻenehana kani e ana i ke kahe o ke kahe, e hoʻouna i ka hawewe kani ultrasonic i ka mea e ana ʻia ma o ka mea ʻike, a laila loaʻa ka hōʻailona rebound, helu i ka kahe kahe e like me ka wikiwiki o ka hoʻolaha ʻana o ka hawewe kani ultrasonic. waena;Hoʻohana ka mīkini kahe electromagnetic i ke kānāwai o Faraday e ana i ka hoʻokomo ʻana o ke kahua magnetic o ka neʻe ʻana o nā mea i hoʻopaʻa ʻia i loko o ka media conductive.

2. Nā kūlana likeʻole e ka hoʻopilikiaʻana i ke kaiapuni: no ka mea, pono e hoʻouna a loaʻa i nā ultrasonic flowmeters nā hōʻailona kani ultrasonic, ua hoʻopilikia nuiʻia lākou e nā mea o waho e like me ka walaʻau a me ka walaʻau, a uaʻoi aku ka maʻalahi o ke kaiapuni ma mua o ka electromagnetic flowmeters.

ʻElectromagnetic flowmeter:

Nā hiʻohiʻona:

1. Kiʻekiʻe pololei, maikaʻi lōʻihi-manawa ana paʻa;

2. Non-occlusive, ʻaʻohe wahi neʻe, a me ka hilinaʻi kiʻekiʻe;

3. Laulā noi ākea, hiki ke ana i ka wai conductive.

Nā ʻokoʻa:

1. Ana kumu: E like me ka mea i oleloia maluna, electromagnetic flowmeter ka hoʻohana 'ana i nā mea uila i hoʻopaʻa 'ia i loko o ka conductive medium i hoʻokomo 'ia e ka waho magnetic kahua ikaika e oscillate a hoololi i ka uila hōʻailona e loaa maoli-manawa kahe ikepili.

2. Nā kūlana like ʻole e ka hoʻopilikia ʻana i ke kaiapuni: No ka mea e loaʻa i nā hawewe electromagnetic kekahi hopena i nā flowmeters electromagnetic, ua maʻalahi ka hoʻohana ʻana i ka palena ma lalo o nā kahua paʻakikī a i ʻole nā ​​kūlana kaʻina hana paʻakikī e like me ka hoʻoili uila uila uila a me ke kukui ikaika ma Asia.
