Me pēhea te whiriwhiri i te mita rere hikohiko tika?

I te wā e whiriwhiri ana i tētahimita rere hikohiko(EMF), me whai whakaaro ki ētahi āhuatanga nui hei whakarite i ngā inenga tika me te pono mō te wā roa:

1. Ngā Whakaritenga Waenga
   Me kawe te wai (te tikanga ≥5 μS/cm), pēnei i:

• Wai (wai paipa, wai para, wai moana)
• Ngā otinga waikawa me te kawakore (umanga matū)
• Parai, penupenu, me te parai kohuke (ngā ranunga totoka-wai he kawe hiko)

Kāore e pai mō ngā wai kore-arahi, pēnei i:

1. • Wai parakore, wai whakapūkara
   • Ngā hinu (penehi, penehīni, tīhiera)
   • Ētahi whakarewa rauropi (hei tauira, te waipiro, te benzene)
2. Te Diameter o te Paipa me te Tere Rere
   Kōwhiria he mita rere e ōrite ana ki te awhe rere e tika ana. Ko te tikanga, me whakamahi i te tere rere o te 1–5 m/s. Mēnā he iti rawa te tere rere, ka pāngia pea te tika o te ine, engari mēnā he tiketike rawa, ka piki ake te ngaronga o te pēhanga.
   Me rite te whānui o te paipa ki te rahi o te mita rere. Mena he iti rawa te tere o te rere, whiriwhiria he whānui iti ake hei whakapai ake i te pumau o te ine.
3. Kōwhiringa Rauemi Hiko me te Arai
   Me whiriwhiri ngā rauemi mō ngā irahiko me te arai i runga i te kaha o te waikura, te pāmahana, me ngā āhuatanga o te kakahu:

   Rauemi	Waenga e tika ana
   Ngā Rauemi Hiko
   316L Kowiri tira	Parakaingaki, wai koretake
   Tantalum (Ta)	Ngā waikawa kaha (hei tauira, te waikawa hauota, te waikawa whanariki)
   Parahi (Pt)	Ngā wai tino waikura, pāmahana teitei
   Taitānia (Ti)	Wai moana, wai kei roto he pūhaumāota
   Ngā Rauemi Whakatakoto
   rapa	Wai whānui, waipara, paru
   PTFE (Teflon)	Ngā waikawa kaha, ngā kawakore kaha
   Neoprene	Ngā wai me ngā matūriki, ngā paru kohuke

4. Ngā Tikanga Tāutanga
   • Te Roa o te Paipa Tika: Ko te roa e taunakitia ana i mua i te mita rere he ≥5 ngā wā o te whānui o te paipa, ā, he ≥2 ngā wā i muri i te mita hei karo i ngā āhuatanga rere e pōrearea ana.
   • Rere Paipa Katoa: Me tāuta te mita rere ki roto i tētahi wāhanga paipa kua kī tonu hei ārai i ngā mirumiru hau me ngā paipa kau kei pā ki te tika o te ine.
   • Ngā Āhuatanga Taiao: Āta karohia te pokanoa hikohiko kaha mai i ngā pūtake pēnei i ngā puku auau rerekē, i ngā motuka rānei; he mea nui te tūhono tika ki te whenua.
5. Tohu Putanga me te Kawa Whakawhitiwhiti Kōrero
   • Ngā Tohu Analog: 4-20mA (tohu ahumahi noa)
   • Whakawhitiwhiti MamatiRS485 (Modbus), HART, Profibus
   • Putanga PātaHe pai mō ngā mahi ine
6. Pūtake Hiko
   • AC 220V/110V (mō ngā tāutanga pumau)
   • DC 24V (mō ngā pūnaha aunoatanga ahumahi)
   • Pūhiko (mō ngā wāhi tawhiti kāore he hiko o waho)
7. Ētahi atu Whakaritenga Motuhake
   • Ine Ahu-ruaMena e hiahiatia ana te ine rere whakamuri, whiriwhiria he tauira e tautoko ana i te ine ahunga-rua.
   • Whakatauranga TiakitangaIP65 (taiao whānui), IP67/IP68 (taiao o waho, taiao ruku rānei).
   • Ngā Whakaritenga Ārai-PahūtangaMō te whakamahinga i roto i ngā wāhi matū hinu, i ngā wāhi morearea rānei, me whiriwhiri he mita rere ātete-pahū.

Mā te whakaaro ki ēnei āhuatanga ka āwhina i a koe ki te whiriwhiri i te mita rere hikohiko tika mō tō tono.
