Nigute ushobora guhitamo urwego rwohereza?

• Intangiriro

Urwego rwamazi yo gupima ni igikoresho gitanga ibipimo byamazi bikomeza.Irashobora gukoreshwa kugirango umenye urwego rwamazi cyangwa ibintu byinshi mugihe runaka.Irashobora gupima urwego rwamazi yibitangazamakuru nkamazi, amazi ya viscous na lisansi, cyangwa itangazamakuru ryumye nkibintu byinshi hamwe nifu.

Urwego rwamazi apima imashini irashobora gukoreshwa mubikorwa bitandukanye nkibikoresho, ibigega ndetse ninzuzi, ibidengeri n'amariba.Ibyohereza imashini bikoreshwa mugutunganya ibikoresho, ibiryo n'ibinyobwa, ingufu, imiti, n’inganda zitunganya amazi.Noneho reka turebe kuri metero nyinshi zikoreshwa mumazi.

• Urwego rwohejuru

Hashingiwe ku ihame ry'uko umuvuduko wa hydrostatike ugereranije n'uburebure bw'amazi, sensor yo mu rwego rwo hejuru ikoresha ingaruka za piezoresistive ya silicon ikwirakwizwa cyangwa sensor ceramic kugirango ihindure ingufu za hydrostatike mubimenyetso byamashanyarazi.Nyuma yubushyuhe bwubushyuhe no gukosora umurongo, bihindurwamo 4-20mADC isanzwe yerekana ibimenyetso bisohoka.Igice cya sensor igice cyamazi ya hydrostatike yoherejwe gishobora gushyirwa mumazi, kandi igice cyohereza gishobora gukosorwa na flange cyangwa bracket, kuburyo byoroshye gushiraho no gukoresha.

Urwego rwohejuru rwibikoresho bikozwe muburyo bwo kwigunga bwakwirakwijwe na silicon yibintu byoroshye, bishobora gushyirwa mubintu cyangwa mumazi kugirango bipime neza uburebure kuva kumpera ya sensor kugera kumazi, hanyuma bigasohora urwego rwamazi binyuze muri 4 - 20mA cyangwa ikimenyetso cya RS485.

• Urwego rukuruzi

Imiterere ya magnetiki flap ishingiye kumahame ya by-pass.Urwego rwamazi mumazi nyamukuru arahuye nibiri mubikoresho bya kontineri.Dukurikije amategeko ya Archimedes, ubwiyunge butangwa na magnetiki ireremba mumazi kandi uburemere bwikaraga bureremba kurwego rwamazi.Iyo urwego rwamazi yubwato rwapimwe ruzamuka rukagwa, kuzenguruka kureremba mumiyoboro nyamukuru ya metero yamazi nayo irazamuka ikagwa.Icyuma gihoraho cya magnetiki kireremba gitwara inkingi itukura numweru mu cyerekezo kugirango uhindure 180 ° unyuze kumurongo wa magneti

Iyo urwego rwamazi ruzamutse, kureremba guhinduka kuva cyera ugahinduka umutuku.Iyo urwego rwamazi ruguye, kureremba guhinduka kuva umutuku uhinduka umweru.Imipaka yera-umutuku nuburebure nyabwo bwurwego rwamazi yo hagati muri kontineri, kugirango tumenye urwego rwamazi.

• Magnetostrictive fluid urwego urwego

Imiterere ya magnetostrictive fluid urwego rwimikorere igizwe numuyoboro wibyuma (wapima inkoni), insinga ya magnetostrictive (wireguide wire), kureremba kureremba (hamwe na rukuruzi ihoraho imbere), nibindi. Umuyoboro kuri wireguide, hamwe na pulse ya magnetiki yumurima bizabyara hafi ya wireguide mugihe umuyaga ukwirakwiza kumurongo wa waveguide.

Ikireremba gitunganijwe hanze yinkoni yo gupima sensor, hanyuma ikireremba kizamuka hejuru no munsi yinkoni yo gupima hamwe no guhindura urwego rwamazi.Hano hari urutonde rwimpeta zihoraho imbere kureremba.Iyo imbaraga za magnetiki zihuye zihuye na magnetiki impeta ya magnetiki ikorwa na float, umurima wa rukuruzi uzenguruka kureremba uhinduka, kuburyo insinga ya waveguide ikozwe mubintu bya magnetostrictive ibyara torsional wave pulse kumwanya wu kureremba.Indwara yoherezwa inyuma yumurongo wa waveguide kumuvuduko uhamye kandi igaragazwa nuburyo bwo gutahura.Mugupima igihe gitandukanya hagati yo kwanduza pulse na torsional wave, umwanya wo kureremba urashobora kugenwa neza, ni ukuvuga umwanya wubuso bwamazi.

• Radiyo Yinjira Kwinjira Ibikoresho Urwego Sensor

Kwinjira kuri radio inshuro nyinshi ni tekinoroji yo kugenzura urwego rwatezimbere kuva kurwego rwa capacitive urwego, rwizewe, rwukuri kandi rushobora gukoreshwa.Nukuzamura ubushobozi bwa capacitive urwego rwo kugenzura.
Ibyo bita radiyo yumurongo wa radiyo bisobanura gusubiranamo kwingufu zamashanyarazi, zigizwe nibintu birwanya ibintu, ubushobozi bwa capacitive hamwe na inductive.Umuyoboro wa radiyo ni umurongo wa radiyo yumurongo wa metero ndende, bityo rero kwinjira kuri radio bishobora kumvikana nko gupima ibyinjira hamwe na radiyo yumurongo mwinshi.

Iyo igikoresho gikora, sensor yicyo gikoresho ikora agaciro ko kwinjira hamwe nurukuta hamwe nuburyo bwapimwe.Iyo urwego rwibintu ruhindutse, agaciro kinjira karahinduka.Igice cyumuzunguruko gihindura agaciro kinjira mubipimo byerekana ibimenyetso byerekana urwego rwibipimo.

• Urwego rwa Ultrasonic

Urwego rwa Ultrasonic ni igikoresho cya digitale igenzurwa na microprocessor.Mu gupima, pulse ultrasonic wave yoherejwe na sensor, kandi amajwi yakirwa na sensor imwe nyuma yo kugaragazwa nubuso bwikintu, hanyuma bigahinduka ikimenyetso cyamashanyarazi.Intera iri hagati ya sensor n'ikintu kiri munsi yikizamini ibarwa mugihe kiri hagati yijwi ryogukwirakwiza no kwakira.

Ibyiza ntabwo ari imashini yimukanwa, kwizerwa cyane, kwishyiriraho byoroshye kandi byoroshye, gupima kudahuza, kandi ntibiterwa nubwiza nubucucike bwamazi.

Ikibi ni uko ubunyangamugayo buri hasi, kandi ikizamini cyoroshye kugira ahantu hatabona.Ntibyemewe gupima icyombo cyumuvuduko nuburyo buhindagurika.

• Urwego rwa Radar

Uburyo bwakazi bwa radar yamazi yo murwego rwohereza ubutumwa bwerekana kwakira.Antenna ya radar yamazi ya metero yohereza amashanyarazi ya elegitoroniki, igaragazwa nubuso bwikintu cyapimwe hanyuma igakirwa na antene.Igihe cya electromagnetic waves kuva kwanduza kwakirwa nikigereranyo cyintera kurwego rwamazi.Urwego rwa radar rwamazi rwerekana igihe cyumuvuduko wa pulse, kandi umuvuduko wo kohereza wa electromagnetic waves uhoraho, noneho intera kuva kurwego rwamazi kugeza antenne ya radar irashobora kubarwa, kugirango umenye urwego rwamazi rwurwego rwamazi.

Mubikorwa bifatika, hariho uburyo bubiri bwa radar yamazi ya metero, aribyo guhinduranya inshuro zikomeza hamwe na pulse.Ikigereranyo cyamazi ya metero hamwe na tekinoroji ihindagurika ikomeza ikoresha ingufu nyinshi, sisitemu enye hamwe na elegitoroniki igoye.Ikigereranyo cyamazi hamwe na tekinoroji ya radar pulse ikoresha ingufu nke, irashobora gukoreshwa na sisitemu ebyiri-ya 24 VDC, byoroshye kugera kumutekano wimbere, uburinganire bwuzuye kandi bwagutse.

• Kuyobora umurongo wa radar urwego

Ihame ryakazi ryo kuyobora umurongo wa radar urwego rwohereza ni kimwe nurwego rwa radar, ariko yohereza microwave pulses ikoresheje umugozi wa sensor cyangwa inkoni.Ikimenyetso gikubita hejuru yubuso, hanyuma kigasubira kuri sensor, hanyuma kigera kumazu ya transmitter.Ibyuma bya elegitoroniki byinjijwe mumazu ya transmitter bigena urwego rwamazi ukurikije igihe bifata kugirango ibimenyetso bigendere kuri sensor hanyuma bigaruke.Ubu bwoko bwa transmitteri ikoreshwa mubikorwa byinganda mubice byose byikoranabuhanga.
