Ni gute icyuma gipima amashanyarazi cyagombye gushyirwaho?

Gushyirahoicyuma gipima imikorere y'amashanyaraziigomba gukurikiza neza amabwiriza kugira ngo irebe ko ibipimo ari ukuri kandi ko birambye. Izi zikurikira ni intambwe z'ingenzi zo gushyiraho n'uburyo bwo kwirinda:

1. Guhitamo aho gushyiramo

• Imiterere y'umuyoboro wuzuye
  Menya neza ko icyuma gipima amazi gihora kiri mu muyoboro wuzuye. Irinde kugishyira hejuru cyane y'umuyoboro cyangwa ahantu gazi ishobora kwirunda. Mu muyoboro utambitse, icyuma gipima amazi kigomba gushyirwa hejuru y'umurongo wo hagati w'umuyoboro (kugira ngo hirindwe ko imyanda iri hasi ihinduka).
• Ibisabwa ku gice cy'imiyoboro igororotse
• Igice cy'imiyoboro igororotse cyo hejuru: ≥ inshuro 5 kugeza ku 10 z'umurambararo w'umuyoboro (bitewe n'imiterere y'udupira n'inkokora).
• Igice cy'imiyoboro igororotse kiri munsi y'amazi: ≥ inshuro 3 kugeza kuri 5 z'umurambararo w'imiyoboro.
  Urugero: Ku muyoboro wa DN100, umuyoboro wo hejuru ugomba kwemeza ko hari igice cy'umuyoboro ugororotse kiri hagati ya mm 500 na 1000.
• Kwirinda ko habaho imbogamizi ku isoko ry'amakuru
  Irinde ibikoresho bikomeye bya elegitoroniki nka moteri nini na transfoma, ukomeze intera ya metero 1 nibura.

2. Ibisabwa ku guhuza imiyoboro

• Ihuza ry'urukiramende
  Menya neza ko ubuso bw'urukiramende buringaniye kandi ukoreshe agakoresho ko gufunga (ibikoresho bigomba kuba bihuye n'uburyo bwapimwe).
  Fata imigozi mu buryo buringaniye kugira ngo wirinde ko amazi asohoka bitewe n'imbaraga zitangana.
• Guhuza umurambararo w'imiyoboro
  Umurambararo w'ikigega cy'amazi ugomba kuba uhuye n'uw'umuyoboro. Niba hakenewe impinduka y'umurambararo, koresha umuyoboro ugabanya cyangwa waguka (inguni y'umuyoboro ≤ 15°).
• Ibisabwa mu gusiga ubutaka
  Sensoreri igomba gushyirwa ku butaka ukwayo, kandi ubushobozi bwo kwirinda guhagarara ku butaka bugomba kuba < 10Ω.
  Niba umuyoboro ukozwe mu bikoresho bikingira (nk'iplastike), ugomba gushyirwaho uruziga rwo hasi hejuru no hepfo.

3. Icyerekezo cyo gushyiraho Sensor

• Gushyiraho ahantu hatambitse
  Umurongo wa electrode ugomba kuba utambitse kugira ngo hirindwe ko uduce twinshi tw’ibice bitagira ingaruka ku gipimo (nk’uko bigaragara ku Ishusho ya 1).
• Gushyiraho mu buryo buhagaze
  Amazi agomba gutemba ava hasi ajya hejuru kugira ngo umuyoboro wuzuye kandi wirinde ko uduce duto dupfunyika (nk'uko bigaragara ku Ishusho ya 2).

4. Imiterere ya Valves z'Imbere n'Inyuma

• Valve yo hejuru
  Intera uvuye kuri sensor igomba kuba inshuro ≥ eshanu z'umurambararo w'umuyoboro. Ni byiza gukoresha valve y'irembo no kwirinda gukoresha valve y'ikinyugunyugu (ishobora gutuma umuvuduko w'amazi uhindagurika).
• Valve yo munsi
  Iyo ikoreshejwe mu kugenzura amazi atembera, igomba kugumana intera ingana n'inshuro ≥ eshatu z'umurambararo w'umuyoboro uvuye kuri sensor.

5. Urwego rwo Kurinda n'Ibidukikije

• Guhitamo amanota ya IP
• Ku bidukikije byumye: IP65 (irinda ivumbi kandi irinda gupfuka).
• Ku bidukikije byo hanze cyangwa ahantu hakonje: IP68 (irinda ivumbi ryose kandi idakingirwa n'amazi).
• Ubushyuhe n'ubushuhe
• Ubushyuhe bw'ikirere: -25°C kugeza 60°C (reba urupapuro rugaragaza imiterere y'igikoresho).
• Ubushuhe: ≤ 95%RH (nta gushonga kw'amazi).

6. Guhuza amashanyarazi

• Gukingira Insinga
  Insinga y'ikimenyetso igomba gukoresha urwego rw'uburinzi bubiri kandi ikarinda umuyoboro w'icyuma utandukanye. Irinde kuyishyira iruhande rw'insinga y'amashanyarazi.
• Ibisobanuro by'ubutaka
  Igice cy'inyuma cy'icyuma gipima, igice cy'inyuma cy'icyuma gihindura insinga, n'urwego rwo kurinda insinga bigomba kuba bifite ishingiro ryizewe. Birabujijwe cyane gusangira insinga y'ubutaka n'ibindi bikoresho.

7. Gukosora amakosa no kuyakira

1. Gupima imyanya ntarengwa
   Iyo umuyoboro wuzuyemo amazi ariko nta mazi asohoka, kora ikosa ryo guhindura (funga valve zo hejuru n'izo hasi).
2. Gupima Ingano y'Iterambere ry'Umuvuduko
   Ku ikoreshwa rya mbere cyangwa nyuma yo gusana, ni byiza gukora isuzuma ry’amazi nyayo hakoreshejwe uburyo bwa volumetric cyangwa uburyo busanzwe bwo gupima.
3. Gukemura ibibazo by'amakosa

• Genzura imbaraga z'ikimenyetso (kigomba kuba > 80% mu bihe bisanzwe).
• Gerageza uburyo electrode idashobora gushyushya (igomba kuba > 20MΩ).
• Genzura niba umuyoboro w'ubutaka uyobora amashanyarazi.

Imiterere y'imikoreshereze

1. Irinde igitutu kibi
   Umuyoboro wo hasi ntugomba kuba munini urenze aho icyuma gipima amazi gisohokera kugira ngo hirindwe ko igice cy'amazi cyangirika bitewe n'umuvuduko mubi uterwa na siphon.
2. Itangazamakuru ribujijwe ryo gutembera ku mazi
   Iyo ingano ya iyoni ya chloride mu buryo bupimwe iri hejuru ya 400ppm, electrode ya Hastelloy cyangwa electrode ya tantalum igomba gutoranywa.
3. Kwita ku bintu biri mu turere tudashobora guturika
   Iyo ishyizwe ahantu hadashobora guturika, igikoresho gifite umutekano mu buryo bwacyo gikurikiza icyemezo cya ATEX cyangwa IECEx kigomba gutoranywa.
