Yintoni inzwa yomgangatho wamanzi?
Inzwa yomgangatho wamanzi sisixhobo esilinganisa inqanaba le-liquid kwisitya esisisigxina esiphezulu okanye esiphantsi kakhulu. Ngokwendlela yokulinganisa inqanaba le-liquid, linokwahlulwa libe ziindidi ezimbini: uhlobo loqhagamshelwano kunye nohlobo olungadibananga. Uhlobo lwegalelo lokuhambisa inqanaba lamanzi esilibizayo ngumlinganiselo woqhagamshelwano, oguqula ubude bomgangatho wolwelo ube ngumqondiso wombane wokuphuma. Kungoku nje sisixhobo sokuhambisa inqanaba lamanzi esisetyenziswa kakhulu.
Ingaba inzwa yomgangatho wamanzi isebenza njani?
Umgaqo osebenzayo we-sensor yenqanaba lamanzi kukuba xa ufakwe kubunzulu obuthile kulwelo oluza kulinganiswa, uxinzelelo kwindawo yangaphambili ye-sensor iguqulwa ibe yinqanaba lokuphakama kwamanzi. Ifomula yokubala ngu Ρ=ρ.g.H+Po, kwifomula P luxinzelelo kumphezulu wolwelo wesixhobo soluvo, ρ luxinaniso lolwelo oluza kulinganiswa, g kukukhawulezisa kwendawo yomxhuzulane, iPo yi Uxinzelelo lwe-atmospheric kumphezulu wolwelo, kwaye H bubunzulu apho inzwa yehla kulwelo.

Isivamvo senqanaba sisixhobo esilungiselelwe ukujonga kunye nokulinganisa amanqanaba olwelo (kwaye ngamanye amaxesha aqinile). Xa inqanaba lolwelo lichongiwe, i-sensor iguqula idatha ebonisiweyo ibe ngumqondiso wombane. Izinzwa zenqanaba zisetyenziselwa ukubeka iliso kumadama, iitanki zeoyile okanye imilambo
Kuphi ukusetyenziswa koluvo lwenqanaba lamanzi?
Ukusetyenziswa kwezinzwa zomgangatho wamanzi kubandakanya ezi zicelo zilandelayo:
1. Umlinganiselo womgangatho wamanzi wamadama kunye namatanki amanzi
2. Umlinganiselo womgangatho wamanzi wemilambo namachibi
3. Umlinganiselo wenqanaba lolwandle
4. Umlinganiselo wenqanaba lolwelo lwe-asidi-base
5. Umlinganiselo wenqanaba le-oyile yeelori zeoyile kunye neebhokisi zeposi
6. Ulawulo lomgangatho wamanzi kwidama lokuqubha
7. Isilumkiso setsunami kunye nokubeka iliso kwinqanaba lolwandle
8. Ulawulo lomgangatho wamanzi wenqaba yokupholisa
9. Ukulawula umgangatho wempompo yogutyulo
10. Ukujongwa okude kwinqanaba lolwelo
