1. Kua arotauhia mō ngā Parshall Flume Hydraulics

• Te mahi tahi me te hoahoa o te hau: Kua hangaia ngā hau Parshall hei huri i te tere rere ki te pikinga taumata wai e taea te ine i tētahi wāhanga "korokoro" motuhake. Ka ine tika ngā mita ultrasonic i tēnei taumata matua (i te nuinga o te wā i te korokoro o runga o te hau, i te wāhanga whakatata rānei) ā, ka whakamahi i ngā tātai tukunga hau Parshall kua whakaritea i mua hei tatau i te tere rere.
• Ngā tawhā hau kua utaina i mua: He maha ngā tauira kei roto ngā pātengi raraunga kua hangaia mō ngā rahi hau Parshall paerewa (hei tauira, ngā korokoro 1-inihi ki te 50-putu) me ō rātou tauwehenga tukunga e rite ana, e whakakore ana i te whakauru tātai ā-ringa me te whakarite kia tutukihia ngā paerewa waipēhi (hei tauira, ASTM D1941).

2. Inenga Kore-Whakauru, Pānga-Iti

• Kore e pā ki te rere: Kei runga ake i te wāhanga ine o te awa Parshall ngā pūoko orooro (kāore he wāhanga e rukuhia ana), kia kore ai e pokanoa ki ngā tauira rere matua o te awa. He mea nui tēnei nā te mea ka whakawhirinaki ngā awa Parshall ki te rere kore e whakakorikoria hei pupuri i te tika.
• Kāore he mōrearea ārai: Kāore i rite ki ngā whakawhiti pēhanga me ngā pereti parenga wai, kāore ngā pūoko ultrasonic e pāngia e te paru, te paru, ngā matūriki e mānu ana e kitea ana i roto i te wai para, te whakamakuku, ngā rerenga ahumahi rānei—he mea nui tēnei mō ngā paipa e whakamahia ana i roto i ngā tono wai paru.

3. Te Tika Teitei i roto i ngā Āhuatanga Rere Tino Hira

• Te kimi taumata tika: Me ine tika ngā taumata o ngā awa Parshall i ngā pūwāhi motuhake (hei tauira, te pūwāhi ine o runga) hei tatau i te rere. Ka tukuna e ngā pūoko ultrasonic te tika o te taumata o te ±0.1% ki te ±0.5% o te tauine katoa, ahakoa he iti noa te aueue o te mata, te ngaru rānei i roto i te awa.
• Te pono o te tatau rere: E whakamahi ana i te whārite tukunga empirical o te awa Parshall Q=C×Hn (ko Q = te tere rere, H = te upoko ine, C = tauwehenga, n = taupū), kua whakauruhia ki ngā raraunga taumata ultrasonic hei whakarite kia taea te whai i ngā hua ki ngā paerewa ahumahi.

4. Te Āheitanga ki ngā Rahi me ngā Whakamahinga o te Parshall Flume

• Hototahi ki ngā rahi paerewa katoa: Ka mahi tahi me ngā kōrere Parshall iti (tauine taiwhanga) ki ngā kōrere nui (ahuwhenua/aruwhenua), mai i ngā kōrere iti (1-inihi te korokoro) ki ngā kōrere nui mō ngā awa, ngā awaawa rānei (50-putu te korokoro).
• Ka taea te whakahaere i ngā awhe rere rerekē: Kua hangaia ngā awa Parshall mō ngā awhe rere motuhake (hei tauira, 0.01 ki te 300+ cfs), ā, ka urutau ngā mita ultrasonic ki ēnei awhe mā te ine i ngā huringa taumata e rite ana, kia tika ai ngā rere iti me ngā rere teitei.

5. Mahi Pakari i roto i ngā Taiao Motuhake mō te Hau

• Ātete ki ngā raruraru e pā ana ki te hau: Ka tātarihia e te tukatuka tohu matatau te haruru o te tauhiuhi, te pahuka, ngā mirumiru hau rānei—he mea noa i roto i ngā hau Parshall nā te tere o te rere i te korokoro.
• Te pakari o te rangi me te taiao: Ka taea e ngā pūoko me ngā whakatauranga IP65/IP66/IP67 te tu atu i te ua, te haumākū, me ngā pāmahana tino kino, he mea nui mō ngā paipa wai o waho i ngā taiao ahuwhenua, wai para, wai ua rānei.
• Hoahoa ārai-whakararuraru: Ka whakaiti i ngā pānui teka mai i te rā, i ngā whakaata mai i ngā pakitara o te paipa wai, i ngā paru rānei e rere ana i runga i te mata o te wai.

6. Ngāwari te Tāutanga me te Whakatikatika

• Te whakamautanga māmā: Ka whakamauhia ngā pūoko ki runga ake i te pūwāhi ine o te hau (i runga i te tauera, i te pae whakawhiti rānei) me te iti o te mahi ā-ringa, kia kore ai e whakarerekētia te hanganga o te hau.
• Whakatikatika tere: Kua whirihorahia i mua mō ngā āhuahanga o te awa Parshall, kia iti ake ai te wā tatūnga. Ka taea e ngā kaiwhakamahi te manatoko i te tika mā te tirotiro taumata ngāwari i ngā tere rere e mōhiotia ana.

7. Raraunga me te Whakaurunga Wā-Tūturu

• Aroturuki tonu: Ka whakarato i te tere rere o te wai, te taumata wai, me ngā raraunga ia wā-tūturu, ka whakaaturia ā-rohe ki runga i te mata, ka tukuna rānei ki ngā SCADA, PLC, ki ngā tūāpapa kapua rānei mā Modbus, 4G/5G, Wi-Fi, LoRa rānei.
• Te takiuru raraunga: Ka penapena i ngā raraunga rere o mua (hei tauira, ngā toharite ia hāora/ia rā, ngā rerenga tihi) mō te pūrongo tutuki i ngā whakaritenga, te whakaritenga whakamakuku, te arotau rānei i te maimoatanga wai para.
• Whakatūpato: Ngā whakatūpato whirihora mō ngā taumata teitei/iti (e tohu ana i ngā aukatinga paipa, i te waipuke rānei) i ngā hapa rānei o te pūoko, e āhei ai te tiaki matatau.

8. He iti te tiaki me te roa o te ora

• Kāore he wāhanga neke: Ka whakakore i te pakaru o ngā wāhanga mīhini, ka whakaiti i te wā kore mahi. Ko te tiaki auau he mea iti noa ki te horoi i ngā pūoko i ia wā (hei tango i te puehu, i te tukutuku pungawerewere rānei) me te tirotiro i ngā whakatikatika.
• Hanganga pakari: Kua hangaia ngā pūoko me ngā tuku kia tu atu ki ngā āhuatanga kino, kia roa ai te ora ahakoa i roto i ngā taiao o waho, o ngā taiao ahumahi rānei.

9. He Utu-whai hua mō ngā Pūnaha Hau

• He iti ake te utu katoa o te mana whakahaere ki te whakataurite ki ngā mita urutomo: Kāore he hiahia mō ngā pūoko ruku wai (e hiahia ana kia whakakapia pinepine nā te waikura, te aukati rānei) me ngā whakarerekētanga rānei ki ngā paipa hiko.
• Whakaitihia ngā utu mahi: He māmā te tāutanga me te iti o te tiaki ka whakaitihia ngā whakapaunga whakahaere i te roanga o te wā.

10. Te Whakatutuki i ngā Paerewa

• E tutuki ana i ngā paerewa o te ao mō ngā inenga o te awa Parshall (hei tauira, ASTM D1941, ngā aratohu ISO) me ngā whakaritenga ture mō te whakahaere rauemi wai, te aroturuki taiao, me te pūrongo tukunga ahumahi.
