1. Whakataki Hua
Mita taumata ultrasonic raupapa LMUHe taputapu ine whakauru-waea kiato e rua ngā waea i whakarewahia e Lanry Instruments. Kei roto he pūoko tirotiro whakauru me te wae tukatuka hiko me te hanganga ātete-rerenga kua hiritia katoatia, e āhei ai te aroturuki tonu i te taumata kore-pa mō ngā wai me ngā rauemi totoka. He pai mō ngā āhuatanga mahi uaua i roto i te mahi whakarewa, matū, hiko, hinu me ētahi atu ahumahi, e tautoko ana te hua i te whakairinga tīwiri me te flange. Mā te whakamahi i te kaupapa ine wā-rere pakari, me te utu pāmahana aunoa me te hangarau tukatuka tohu atamai, ka whakaputa pumau i ngā tohu anaro paerewa 4-20mA, hei otinga whānui mō te aroturuki taumata tāke me te silo.
Te raupapa LMUkei roto ko ngā tauira e whitu kua whakarōpūtia e te whānuitanga ine mōrahi: LMU4, LMU6, LMU8, LMU12, LMU15, LMU20 me LMU30, me ngā whānuitanga ine wai e kapi ana i te 4m ki te 30m. Mō ngā rauemi totoka, ka ngawari te marara me te mimiti o ngā ngaru ultrasonic e te paura, nō reira ko te whānuitanga ine whai hua he 50% noa iho i tērā i roto i ngā āhuatanga mahi wai. Me ōrite te kōwhiringa tauira ki te taiao tāutanga i te papaanga me ngā āhuatanga rauemi. Ka eke te waeine katoa ki te taumata tiaki IP67; he ātete hauhautanga me te ātete kawakore tōna uhi o waho whakarewa, e āhei ai te mahi pumau mō te wā roa i raro i te -40℃~80℃ me te ±0.1MPa pēhanga noa.
2. Te Mātāpono Ine Matua
Ka oti te ine tawhiti i te taputapu mā tetikanga oro wā-o-te-rerenga: ka tukuna e te pūoko ngā pāorooro ultrasonic ki raro. Whai muri i te pānga ki te mata o te rauemi, ka whakaatahia ngā ngaru oro ki te pūoko. Ka tuhia e te mita te wā t i waenga i te tuku me te whiwhinga, ā, ka tatau i te tawhiti D mai i te pūoko ki te mata o te rauemi me te tere oro c, e whai ana i te tātai: D=c·t/2.
Ka whakaurua e ngā kaiwhakahaere te teitei katoa o te tāutanga H (te tawhiti o te tāke kau) o te tāke i mua i te wā, ā, ka hurihia aunoa e te mita te taumata L=HD i te wā tūturu. Ka arotakehia e te pūoko pāmahana whakauru kua hangaia te pehanga tere oro i puta mai i ngā huringa pāmahana i te wā tūturu hei whakakore i ngā hapa ine mai i te pāmahana taiao.
He tawhiti ārai (rohe mate B) tō te taputapu, ā, kāore e taea te tautuhi i ngā whakaata. Kaua te tauine katoa F i whakatakotoria i te wā whakatikatika e toro atu ki roto i te tawhiti ārai. Ka piki ake te tawhiti ārai o ia tauira mai i te 0.2m ki te 1.2m, ā, me nui ake te wāhi tāutanga kua rahuitia mō ngā tauira tawhiti. E rua noa ngā huinga tawhā (te teitei o te tāke kau me te tauine katoa) me whakauru kia tere ai te whakatikatika. E toru ngā pātene whakapūmau me te whakaaturanga LCD nui e 4-mati e tautoko ana i te patuiro me te pānui i te wāhi.
3. Ngā Āhuatanga Matua o te Hua
- Hoahoa kiato whakauru: Kua whakauruhia te pūoko me te wae hiko hei wahi kotahi, me ngā kōwhiringa whakairinga tīwiri/flange hei ngāwari ki te wetewete me te tāuta me te kore he waea motuhake.
- Parenga maha-ara iahiko: Ngā kōwae parenga ngaohiko nui, ngaohiko nui me te uira kua hangaia ki roto, e urutau ana ki ngā taiao tuku hiko uaua i roto i ngā wheketere.
- He kaha ātete-whakararuraru pai rawa atu: Ka tātarihia e te rauropi tohu mamati atamai te raruraru i puta mai i te mamaoa, te puehu, ngā tautoko tāke me ngā whakaohooho, kia uru ai ki ngā āhuatanga mahi tāke uaua.
- Putanga tohu paerewa: Putanga iahiko 4-20mA me te kaha kawenga 0~500Ω, ka taea te hono tika ki te PLC, ki ngā taputapu hopu me ētahi atu taputapu whakahaere ahumahi; 4mA e rite ana ki te tāke kau, ko te 20mA e rite ana ki te tāke kī.
- Whānui te urutau ki ngā āhuatanga mahi: He whare hiko whakarewa, he pūoko ABS, he ātete puehu IP67, he ātete ki te wai me te kawakore, e tika ana mō ngā taiao pāmahana iti/teitei me te pēhanga paku.
- Koki hihi ngāwari: Koki hihi 8° (3dB) mō ngā tauira tawhiti-poto 4/6/8m; koki hihi 5° (3dB) mō ngā tauira tawhiti-roa 12~30m, e whakaiti ana i te pokanoa o te haruru mai i ngā pakitara tāke me te whakanui ake i te pumau o te ine tawhiti-roa.
4. Ngā horopaki tono
He pai te mahi a te LMU, arā, kāore e pā atu, ā, he hototahi ki ngā mea totoka me ngā mea wai, ā, e whakamahia whānuitia ana tēnei raupapa LMU hei aroturuki i ngā whare rokiroki ahumahi:
- Ahumahi matū: Te aroturukitanga taumata o ngā tāke rokiroki waikawa-pūtake, ngā tāke whakahaere parakaingaki me ngā tāke matū;
- Ahumahi hiko: Ngā tāke wai e rere ana, ngā silos pungarehu rere me ngā tāke paru desulfurization;
- Ahumahi whakarewa: Ngā puna wai whakamatao, ngā whare kohuke me ngā tāke paru para;
- Ahumahi hinu: Ngā tāke ārai hinu mata me ngā puna waipara wehewehe hinu;
- Rokiroki whānui: Te ine i te taumata totoka o ngā putunga witi, ngā ipu matūriki kirihou me ngā papa onepu.
5.Whakarāpopototanga
Te raupapa LMUKo te tuku taumata ultrasonic whakauru he taputapu kiato waea-rua mō te ine taumata wai me te totoka kore-pa i roto i ngā ahumahi matū, hiko, whakarewa me te hinu. Mā te whakamahi i te kaupapa wā-rere me te utu pāmahana, he whare IP67 tōna, he tiaki uira me te ngaohiko nui, he putanga 4-20mA me te tika 0.2%FS. He rerekē ngā koki hihi e pai ana mō ngā whānuitanga ine. Kāore he waikura, he piri rānei o ngā rauemi, he iti noa te tiaki e tukuna ana mō ngā tāke, ngā puna kaukau me ngā silo i raro i ngā āhuatanga mahi uaua.
