Ibisobanuro
Metero zitemba nibikoresho byingenzi mugucunga inganda, gupima ingufu, no gukurikirana ibidukikije. Uru rupapuro rugereranya amahame yakazi, ibiranga tekiniki, hamwe nuburyo busanzwe bwa metero zitwara amashanyarazi, metero zitwara ultrasonic, na metero zitemba. Imashini zitwara amashanyarazi zikwiranye n'amazi atwara ibintu, metero zitwara ultrasonic zitanga ibipimo bidahuye neza, kandi metero zitemba zitanga ibisubizo bitandukanye kubitangazamakuru bitandukanye bya gaze (urugero, gaze gasanzwe, gaze munganda). Ubushakashatsi bwerekana ko guhitamo metero ikwiye bishobora kunoza neza ibipimo byo gupima (ikosa <± 0.5%), kugabanya gukoresha ingufu (15% - 30% kuzigama), no kunoza imikorere yo kugenzura imikorere.
1. Ibipimo bya Electromagnetic Flow Meters
1.1 Ihame ry'akazi
Hashingiwe ku Mategeko ya Faraday yo Kwinjiza Electromagnetic, Amazi atwara ibintu anyura mu murima wa rukuruzi atanga ingufu zingana n’umuvuduko ukabije, ugaragazwa na electrode.
1.2 Ibiranga tekinike
- Itangazamakuru rikwiranye: Amazi meza (conducivite ≥5 μS / cm), nk'amazi, acide, alkalis, na slurries.
- Ibyiza:
- Nta bice byimuka, birwanya kwambara, ubuzima burebure
- Ikigereranyo kinini cyo gupima (0.1-15 m / s), gutakaza umuvuduko muke
- Ukuri kwinshi (± 0.2% - ± 0.5%), gupima ibyerekezo byombi
- Imipaka:
- Ntibikwiye kumazi adatwara (urugero, amavuta, amazi meza)
- Birashoboka kwivanga mubituba cyangwa ibice bikomeye
1.3
- Amazi ya Komine / Amazi mabi: Gukurikirana imigozi minini (DN300 +)
- Inganda zikora imiti: gupima amazi yangirika (urugero, aside sulfurike, hydroxide ya sodium)
- Ibiryo / Imiti: Ibishushanyo by'isuku (urugero, isuku ya CIP)
2. Ibipimo bya Ultrasonic
2.1 Ihame ry'akazi
Gupima umuvuduko ukabije ukoresheje transit-time itandukaniro (igihe-cyo guhaguruka) cyangwa Doppler ingaruka. Ubwoko bubiri bw'ingenzi:
- Clamp-on (Non-invasive): Kwiyubaka byoroshye
- Kwinjiza: Birakwiriye imiyoboro minini
2.2 Ibiranga tekinike
- Itangazamakuru ribereye: Amazi na gaze (moderi yihariye irahari), ishyigikira icyerekezo kimwe / byinshi
- Ibyiza:
- Nta kugabanuka k'umuvuduko, nibyiza kumazi menshi-yuzuye (urugero, amavuta ya peteroli)
- Ikigereranyo kinini cyo gupima (0.01-25 m / s), ubunyangamugayo bugera kuri ± 0.5%
- Urashobora gushirwa kumurongo, kubungabunga bike
- Imipaka:
- Biterwa nibikoresho byumuyoboro (urugero, ibyuma bishobora gutera ibimenyetso) hamwe na fluid homogeneity
- Ibipimo bihanitse bisaba kugenda neza (irinde imvururu)
2.3
- Amavuta na gaze: Gukurikirana imiyoboro ndende
- Sisitemu ya HVAC: Gupima ingufu kumazi akonje / ashyushya
- Gukurikirana Ibidukikije: Gupima imigezi / imigezi itemba (moderi zigendanwa)
3. Ibipimo bya gazi
3.1 Ubwoko bwingenzi nibiranga
| Andika | Ihame | Imyuka ikwiranye | Ibyiza | Imipaka |
|---|---|---|---|---|
| Misa yubushyuhe | Gushyushya | Imyuka isukuye (umwuka, N₂) | Urujya n'uruza rwinshi, nta temp / indishyi | Ntibikwiriye imyuka yuzuye / ivumbi |
| Vortex | Umuhanda wa Kármán | Umwuka, gaze gasanzwe | Umuvuduko mwinshi / umuvuduko | Ubushobozi buke bwo gutemba |
| Turbine | Kuzunguruka | Gazi isanzwe, LPG | Ukuri kwinshi (± 0.5% - ± 1%) | Irasaba gufata neza |
| Imyuka Itandukanye (Orifice) | Ihame rya Bernoulli | Imyuka yo mu nganda | Igiciro gito, gisanzwe | Gutakaza umuvuduko uhoraho (~ 30%) |
3.2
- Urwego rw'ingufu: Kohereza gaze gasanzwe
- Gukora Semiconductor Gukora: Kugenzura gaze-isukuye cyane (Ar, H₂)
- Igenzura ry'ibyuka bihumanya ikirere: Gupima gaze (SO₂, NOₓ) gupima umuvuduko
4. Amabwiriza yo kugereranya no gutoranya
| Parameter | Amashanyarazi | Ultrasonic | Gazi (Urugero rw'ubushyuhe) |
|---|---|---|---|
| Itangazamakuru rikwiye | Amazi meza | Amazi / imyuka | Imyuka |
| Ukuri | ± 0.2% –0.5% | ± 0.5% –1% | ± 1% –2% |
| Gutakaza igitutu | Nta na kimwe | Nta na kimwe | Ntarengwa |
| Kwinjiza | Umuyoboro wuzuye, hasi | Irasaba kwiruka neza | Irinde kunyeganyega |
| Igiciro | Hagati | Hagati | Hagati |
Ibipimo byo gutoranya:
- Igipimo cyamazi: Electromagnetic kumazi atwara; ultrasonic kubitangazamakuru bitayobora / byangiza.
- Gupima gaze: Ubushyuhe bwa gaze zisukuye; umuyaga w'amazi; turbine yo kwimura.
- Ibikenewe bidasanzwe: Porogaramu yisuku isaba ibishushanyo-bidafite umwanya; itangazamakuru ryubushyuhe bwo hejuru rikeneye ibikoresho birwanya ubushyuhe.
5. Imyanzuro ninzira zizaza
- Imashini zitwara amashanyarazi zikoresha ingufu za chimique / amazi, hamwe niterambere ryigihe kizaza mugupima amazi make (urugero, amazi ya ultrapure).
- Ibipimo bya Ultrasonic bigenda byiyongera mumazi meza / gucunga ingufu kubera inyungu zidahuye.
- Ibipimo bya gazi bigenda byiyongera kubintu byinshi (urugero, temp / igitutu indishyi + isesengura ryibigize) kugirango bisobanuke neza.
- Byuzuye bya seriveri hamwe na software idafite module, ishyigikira RS485 GPRS / 4g / WIFI / LORA / LORAWANKubindi bisobanuro bya metero yamakuru,
