Xa kufakwa i-flowmeter ye-electromagnetic, kufuneka kugxilwe kwizinto ezintathu eziphambili: iimeko zentsimi yokuhamba, indawo yokufakela, kunye nokuphazamiseka kwendalo ukuze kuthintelwe ukuchaphazela ukuchaneka kokulinganisa.
1. Qinisekisa ukuba intsimi yokuhamba kwamanzi izinzile
- Umbhobho kufuneka usebenze ngombane opheleleyo, uphephe indawo enganeleyo yombane ophakathi okanye igesi ukuthintela ukuguquguquka kwesignali.
- Iindawo zepayipi ezithe tye ngaphambi nasemva kwemitha kufuneka zihlangabezane neemfuno—ngokuqhelekileyo ubukhulu bepayipi buphindwe kalishumi (10D) ngaphambi nakahlanu ububanzi bepayipi (5D) emva koko. Yigcine kude nezinto eziphazamisa ukuhamba kwamanzi ezifana neengqiniba, ii-tee, kunye neevalvu.
- Isantya sokuhamba esiphakathi kufuneka sibe ngaphakathi koluhlu olulinganisiweyo lwemitha (ngokubanzi yi-0.5-10m/s). Isantya sokuhamba esiphantsi kakhulu sinokubangela ukuphazamiseka kwengxolo, kwaye ukuphakama kakhulu kunokuguguleka kwelayini.
2. Iimfuno zesikhundla kunye nendlela yokufakela
- Ii-electrode kufuneka zinxibelelane ngokupheleleyo nesixhobo sombane. Kukhethwa ukufakela ngokuthe tye (ii-electrode kwicala elithe tye), kuthintelwe ukufakelwa ngokuthe nkqo ngee-electrode ezijonge phezulu (ukuqokelelana komoya) okanye ezantsi (ukuqokelelana kwe-slag).
- Ziphephe iindawo ezinokuba ne-turbulence kunye namaqamza afana nee-pump outlets kunye nee-control valves. Ukuba kuyimfuneko ukufaka, yongeza iindawo ezithe tye zepayipi okanye ufake iziqinisi zokuhamba kwamanzi.
- Imitha kufuneka ibekwe kakuhle ngomhlaba ozimeleyo (ukuxhathisa komhlaba ＜10Ω). Musa ukwabelana ngomhlaba nezixhobo zamandla ukuthintela ukuphazamiseka kwesignali.
3. Kuphephe ukuphazamiseka kokusingqongileyo
- Gcina kude nemithombo enamandla yokuphazamiseka kwe-electromagnetic efana nee-frequency converters, ii-motor ezinkulu, kunye neentambo ze-high-voltage ukuthintela ukuphazamiseka kwesignali.
- Faka kwindawo eyomileyo, enomoya ococekileyo. Kuphephe ukukhanya kwelanga ngqo, ukufuma okuphezulu, okanye iindawo ezinegesi ezonakalisayo ukukhusela isixhobo sokuguqula kunye nezixhobo ze-elektroniki.
- Qinisekisa ukuba ubushushu bendawo yokufakela bungaphakathi koluhlu olulinganisiweyo lwemitha ukuze kuthintelwe ukuchaphazela ukusebenza kweesekethe zangaphakathi kunye nezinto zokufaka ulwelo.
