Ihe owuwu

(1) sensọ:

Ihe mmetụta ahụ bụ nke kachasị nke catheter na-atụ ihe, electrode a na-atụ ihe, eriri mkpagharị, isi ígwè, magnet na ụlọ.

Ọkpụkpọ a na-atụ ihe: Ọ bụ eriri igwe anaghị agba nchara, lining na flange jikọtara ya, ọ bụkwa ihe na-ebu maka nha mmiri mmiri na saịtị a ga-atụ.

Eletrọd na-atụ: otu ụzọ elektrọd arụnyere na mgbidi dị n'ime nke ebe a na-atụ ihe, na-aga n'ihu na ntụzịaka axial, nke mere na mmiri nha nha na-ewepụta akara.

Igwe ihe na-akpali akpali: Igwe ihe mkpali elu na nke ala na-emepụta oghere ndọta na catheter nha.

Ígwè isi na ihe ndọta: A na-ewebata oghere ndọta site na eriri mkpagharị ahụ n'ime mmiri mmiri wee mepụta sekit magnetik.

Shell: mpụta nkwakọ ngwaahịa.

(2) Ntụgharị:

Ọ bụ mita nke abụọ nwere ọgụgụ isi, nke na-eme ka mgbama na-erugharị na-amụba ma na-agbakọ ya na kọmputa nwere otu mgbawa iji gosipụta mgbaba na ọnụọgụ ọnụọgụ, ma nwee ike ịmepụta pulse, analog current na ihe mgbaàmà ndị ọzọ maka nha ma ọ bụ njikwa mmiri na-asọ.

(3) Ụdị mgbakọ ngwaahịa:

E kewara ya ụzọ abụọ: ụdị agbakwunyere na ụdị nkewa.

Ụdị agbakwunyere: A na-etinye ihe mmetụta na ihe ntụgharị n'otu mpempe.

Ụdị nkewa: A na-etinye ihe mmetụta na ihe ntụgharị iche iche, a na-emepụta usoro mita eruba site na ijikọ eriri.Iji mezuo ihe achọrọ maka nha mgbasa ozi dị iche iche, ihe mkpuchi na electrode nke ihe mmetụta nwere ike ịnwe ọtụtụ nhọrọ.

Ụkpụrụ ọrụ

Ụkpụrụ na-arụ ọrụ nke flumeter electromagnetic dabere na iwu Faraday nke ntinye ọkụ eletrik.Ya bụ, mgbe mmiri mmiri na-eduzi na-agafe na igwe eletrik eletrọnịkị, a ga-emepụta ike electromotive na-ebute n'ime onye nduzi.Ike electromotive a na-ebute na-adaba na ọnụego nke mmiri na-eduzi, ike induction magnetik, na obosara nke onye nduzi (dayameta dị n'ime nke flowmeter), dị ka egosiri na ọnụ ọgụgụ ahụ.

A na-achọpụta ike electromotive a na-akpata site na otu ụzọ electrodes na mgbidi nke igwe na-agba ọsọ, na enwere ike nweta ọsọ ọsọ site na ngụkọ.

Nhazi ike electromotive a kpalitere bụ: E=KBVD

Na usoro: E kpalitere ike;D nha tube n'ime dayameta;

B ike induction magnetik;V nkezi ọsọ ọsọ;

K bụ ọnụọgụgụ metụtara nkesa ndọta na ogologo axial.
