Tātaritanga Pēhanga-Rōrahi-Mahana (PVT)He mea nui kia mārama ai ki te whanonga o ngā wai puna wai i raro i ngā āhuatanga rerekē i roto i te umanga hinu. Mā tēnei tātaritanga ka whai wāhi ngā whakataunga nui mō te whakahaere puna wai, ngā rautaki whakaputa, me te arotau whakaora.
He mea nui ki te whai huaTātaritanga PVThe inenga tika okiato waime te matotoru, e whakaatu ana i te hanganga me ngā āhuatanga rere ongā wai o te puna waiHe maha ngā wā ka whakaroa, ka hē pea ngā mahi o ngā tikanga taiwhanga tuku iho nā te whakahaeretanga o te tauira.
Te Otinga Whakakotahi a Lonnmeter mō ngā Rangahau PVT
Hei kaiwhakarato matua mō ngā otinga whakahaere tukanga ā-roto, ka tukuna e Lonnmeter tētahi otinga whakarerekē-kēmu me ānangā mita mātotoru ā-rotomengā mita matotoru. Ka whakaratohia e ēnei taputapu matatau ngā raraunga tika, wā-tūturu mōTātaritanga PVT o ngā wai puna wai, e āhei ai ngā kaihangarau ki te whakatau whai whakaaro tere me te whai hua. I hangaia mō ngā āhuatanga uaua o ngā puna hinu, he pakari, he ngāwari ki te whakamahi, he tino pono hoki ngā mita ā-roto, ngā pūoko tukanga ā-roto rānei a Lonnmeter, ā, he pai rawa atu mōtātaritanga PVT hinu.
Ko ngā mita matotoru me te matotoru ā-roto a Lonnmeter he otinga whakakotahi kaha mōTātaritanga PVT mō ngā puna hinuTeIne mātotoru LONN700āhei ai te tikakiato waite ine i roto i te awa tukanga, i te mea ka whakaratohia e ngā mita matotoru ngā raraunga matotoru wā-tūturu. Mā te mahi tahi, ka tukuna e ēnei taputapu te āhua whānui o te wai, he mea nui mō te māramawai punawhanonga. Mā te whakauru i ngā mita o runga ake nei, ka taea e ngā miihini te aroturuki i ngā āhuatanga matua me te kore e hiahiatia he tauira ā-ringa, ka whakaiti i ngā hapa i puta mai i te mahi ā-ringa auau. Ka whakaiti i te roa me te nui o te mahi hei tauira ā-ringa, ā, ka whakapai ake i te whai huatanga o te mahi.
Pakari me te Hangarau Pūoko Pai rawa atu
Kua hangaia ngā mita a Lonnmeter kia tū atu ki ngā āhuatanga uaua o te hinu me te hau.mita mātotoru wai ā-rotohe mea hanga mai i ngā rauemi pakari pērā i te maitai kore waikura, te Hastelloy, te Titanium rānei, kia pai ai te hototahi ki ngā mea waikurangā wai o te puna wai. Ka mahi i ngā pēhanga tae atu ki te 1 MPa me ngā pāmahana wai mai i te -10°C ki te 120°C, me ngā pāmahana taiao mai i te -40°C ki te 85°C. He pakari ake te mita matotoru, ka taea te whakahaere i ngā pēhanga tae atu ki te 10 MPa (ka taea te whakarite) me ngā pāmahana tae atu ki te 450°C. E tutuki ana i ngā taputapu e rua ngā paerewa tiaki taiao teitei (IP67/IP68) me ngā whakatauranga ātete-pahūtanga (ExdIIBT4 mō te matotoru, ExdIIBT6 mō te mātotoru), e whakarite ana i te haumaru i ngā wāhi morearea. Mā tēnei hangarau pūoko pai rawa atu ka whakamanahia te pono mō te wā roa, ka whakaitihia te wā kore mahi i roto itātaritanga PVT hinu.

Ngā Mita Matotoru
Ngā Painga o te Ine i te Matotoru me te Matatini Whakakotahi
Ko te whakaurunga o ngā inenga mātotoru me te matotoru he tūāpapa mō te whai huatangaTātaritanga PVT mō ngā puna hinu. Te mātotoru o te waie whakarato ana i ngā māramatanga ki te hanganga me te whanonga ā-wāhanga ongā wai o te puna wai, ko te matotoru ia te mea e whakatau ana i ngā āhuatanga rere e tino hira ana mō ngā matapae whakaputa. Mā te whakamahi i ngā mita ā-roto a Lonnmeter, ka taea e ngā kaihangarau te whiwhi i ngā inenga e rua i te wā kotahi, ka taea ai te whakatauira wai whānui. Mā ngā raraunga wā-tūturu ka taea te whakarerekē tonu, te whakapai ake i te whakahaere tukanga me te whakaiti i te mōrearea o ngā take whakaputa. Mā tēnei huarahi whakakotahi ka whakarei ake i te tika o ngā whakatauira puna, ka arotau i ngā rautaki tango, ā, ka tautoko i ngā mahi utu-whai hua, ka waiho hei mea tino nui mōtātaritanga PVT hinu.
Te Tika, te Tere, me te Pono
He tino pai te mahi a ngā mita a Lonnmeter mō te tika, te tere, me te pono. Ka tutuki i te mita mātotoru LONN700 te tika o te ±0.002 g/cm³ (±0.25%) me te auautanga o te ±0.0001 g/cm³ (±0.1%), me te wā urupare o te 2 hēkona noa iho. Ka tukuna e te mita matotoru te tika o te ±3.0% me te auautanga o te ±1%, me te wā urupare o te 5 hēkona. Mā ēnei wā urupare tere ka whakarite kia tata tonu te raraunga mō te whakahaere tukanga hihiri. Ko te hoahoa kore tiaki, kāore he wāhanga neke, ka whakarei ake i te pono, ka whakaiti i ngā utu whakahaere me te whakarite kia rite tonu te mahi i roto iTātaritanga PVT o ngā wai puna wai.
| Ine | Ine Matotoru | Ine Matotoru |
| Te tika | ±0.002 karamu/cm³ (±0.25%) | ±3.0% |
| Te āheinga ki te whakahoki anō | ±0.0001 karamu/cm³ (±0.1%) | ±1% |
| Wā Whakautu | 2 hēkona | 5 hēkona |
Ngā Āheinga Whakahaere Whānui
He mea hanga ngā mita a Lonnmeter kia maha ngā whakamahinga, kia taea ai te whakamahi i ngā momo āhuatanga me ngā momo wai.mita mātotoru wai ā-rotoka taea te whakahaere i ngā wai he matotoru tae atu ki te 2000 cP, ā, he pai hoki mō ngā wai kei roto ngā matūriki totoka, he mea tino pai mō ngā wai matatiningā wai o te puna wai. Ka tautoko te mita matotoru i te whānuitanga matotoru o te 1 ki te 1,000,000 cP, e kapi ana i ngā wai matotoru iti me ngā wai matotoru teitei. Me ngā whānuitanga pēhanga me te pāmahana kua whakaritea mō ngā tono hinu me te hau, he pai ēnei taputapu mō ngā mahi taiwhanga me ngā mahi mara.Tātaritanga PVT. Mā te kaha ki te mahi i roto i ngā āhuatanga tino kino ka taea te whakarite kia pono te mahi puta noa i ngā āhuatanga rerekē.
Te Whakaritenga Rahi Tauira Iti rawa
He rerekē ngā tikanga tuku iho e hiahia ana ki te tango me te tātari i ngā tauira wai, ka ine ngā mita ā-roto a Lonnmeterkiato waime te matotoru i roto tonu i te awa tukanga. Mā tēnei ka kore e hiahiatia he tauira motuhake, ka whakaiti i te mōrearea o ngā hapa, o te poke rānei, ā, ka whakaiti i te whakahaere tauira. MōTātaritanga PVT, i ngā wā kāore pea e wātea ana te tauira, he tino painga tēnei āhuatanga, e whakarite ana i ngā inenga tika me te kore e whakararuraru i te tukanga.
Te Whakangāwari me te Māmā o te Whakahaere
Kua hangaia ngā mita ā-roto o Lonnmeter hei whakangāwari i te kaiwhakamahi. He "mono-ā-ringa" ngā mita matotoru me te matotoru, e āhei ai te tāutanga tere me te kore he tatūnga uaua. Ka hono pai ki ngā pūnaha whakahaere tukanga mā roto i ngā tohu 4-20mA, RS485 rānei, e whakarato ana i ngā raraunga wā-tūturu mō te whakatau tere. Ka whakaitihia e te hoahoa kore-tiaki ngā utu whakahaere me te wā kore mahi, ka waiho ēnei taputapu hei whiringa whai hua mā tetātaritanga PVT hinuMā te ngāwari o te whakamahi ka taea e ngā kaihangarau te arotahi ki te tātari, kaua ki te whakahaere taputapu.
Te Whakataurite ki Ētahi Atu Hangarau
He rerekē ngā painga o ngā mita a Lonnmeter i ngā hangarau kē atu. Mō te ine i te mātotoru, he mea noa ngā mita Coriolis, he tino tika engari he nui ake te utu, ā, he uaua ake hoki nā te mea he mahi takirua tā rātou ki te ine i te rere o te papatipu.ine mātotoru marau whakarārangihe iti ake te utu mō ngā tono e aro ana ki te mātotoru anake. Mō te mātotoru, kāore i te pai ngā mita viscometer hurihuri mō te whakamahi ā-roto nā te uaua o te miihini me ngā hiahia tiaki. He rerekē, ko te mita viscometer wiri a Lonnmeter, he mea arotau mō te ine ā-roto tonu, e tuku ana i te māmā me te roa. Mā te kaha ki te tiki i ngā mita mātotoru me te mātotoru mai i Lonnmeter ka whakarite i te hototahitanga me te whakaurunga ngāwari, he painga matua mōTātaritanga PVT mō ngā puna hinu.
| Hangarau | Te Otinga a Lonnmeter | Rerekē (hei tauira, Coriolis, Rotational) |
| Te Ine i te Kiato | Mārau whakarārangi, utu iti, ā-roto | Coriolis, tika engari he utu nui |
| Te Ine i te Matatini | Huānga wiri, ā-roto, iti te tiaki | Hurihuri, uaua, tiaki teitei ake |
| Whakaurunga | Kaihanga kotahi, maeneene | Tērā pea e hiahiatia ana he maha ngā kaihoko |
