Ina whakahaerehia e koe te aroturuki i te tukunga wai para, te maimoatanga wai para, te whakamakuku rānei, ko te whiriwhiri i tētahi mita rere awa tuwhera e tika ana ka whakatau tika i te tika o te ine, te tutuki i ngā ture me te mahi tiaki roa. He maha ngā miihini e wareware ana ki tētahi mea nui: kāore he mita rere awa tuwhera whānui e mahi pai ana mō ia wāhi. Ko tōna mahi e whakawhirinaki nui ana ki te ōrite ki tō hanganga waipēhi, ki tō hanganga waipēhi rānei kua tāutahia. Nō reira, ko te pātai matua tonu: ko tēhea mita rere awa tuwhera e pai ana mō te āhua o tō awapēhi, o tō awapēhi rānei?
Ko ngā pā wai me ngā awaawa he taputapu ine matua e hanga ana i tētahi hononga pāngarau pumau i waenga i te taumata wai me te tere rere. Ko ngā pā wai, tae atu ki ngā pā wai tapatoru V-notch me ngā pā wai tapawhā, ka hanga he ārai puta noa i te awaawa, ka akiaki i te wai kia maringi ki runga i ngā kōhao kua whakaritea. He tino aro nui ngā pā wai V-notch mō ngā āhuatanga rere iti, e whakamahia whānuitia ana mō ngā putanga wai para iti me ngā pūnaha maimoatanga taiwhanga. Heoi anō, ka hangaia e ngā pā wai ngā puna o runga i te awa, ka kohikohi ngāwari ngā paru, te paru me ngā paru e mānu ana. Me horoi pinepine, ki te kore ka whakapohehetia ngā pānui taumata wai, ka puta he raraunga rere kore pono.
Ko ngā kōrere, pērā i te kōrere Parshall rongonui o te ao, ka whakawhāiti i ngā wāhanga whakawhiti o te awa hei whakatere i te rere ki te tere nui i roto i te wāhanga korokoro. Nā te tere rere tere, he kaha horoi-ake ngā kōrere, ā, ka ātete ki te kohikohi paru. Nā reira i pai ai rātou mō te paru mata, te wai para ahumahi me te onepu me ngā matūriki totoka. Ki te whakatauritea ki ngā pā wai, he iti ake te ngaronga o te pane o ngā kōrere, ā, ka taea te totohu ki raro, engari me hanga tika, me whakarite kia tika te tāutanga.
Ka tatauhia e ngā mita rere awa tuwhera-tuwhera ultrasonic hou te rōrahi rere mā te ine i te hohonutanga wai i te wā tūturu, me te whakamahi i ngā tātai waipēhi kua whakaritea mō ngā pā wai, ngā awa rānei. Heoi, kāore ngā tuku katoa e tautoko ana i te whare pukapuka katoa o ngā whārite awa wai. Ko ētahi taputapu iti te utu he iti noa ngā kōtaha awa e tukuna ana. Ki te hono koe i tētahi mita me te kore he tawhā tika ki tētahi awa Parshall, ki tētahi pā wai tapatoru rānei, ka whiwhi koe i ngā putanga rere ōrite engari he hē rawa, ahakoa he āhua noa ngā pānui taumata. He mahanga noa tēnei i roto i te hoko whenua.
Haunga te hototahitanga o te kōtaha, me arotake e koe ngā āhuatanga mahi tūturu o te papaanga. Mō te tukunga wai ma me te iti o te ihirangi totoka, ka taea e te mita rere kua whakaritea mō ngā pā wai V te whakarato i ngā hua ine pumau, whai hua hoki. Mō te paru o te tāone me ngā poke taumaha, whiriwhiria he mita e tino hototahi ana ki ngā huinga raraunga o te awa Parshall, me te whakaū i te mahi ārai-whakararuraru ki te mamaoa, te rehu wai me te ngangau o te mata i te papaanga. Me aro atu hoki ki ngā mahi whakawhitiwhiti kōrero. Mā ngā putanga M-Bus, Modbus-RTU, HART rānei ka taea te tukuake raraunga mamao mō te pūrongo ture taiao, ka whakakore i ngā hapa tuhi ā-ringa.
Kāore hoki e taea te wareware i ngā whakaritenga tāutanga. Me whai rawaka ngā wāhanga awaawa tika o runga me raro i ngā pā wai me ngā awaawa kia tau ai ngā tauira rere. Ahakoa te mita rere awaawa tuwhera tino pai rawa atu, ka pāngia e te hē o te tika mena ka kore e tutuki ngā whakaritenga i ngā mahi ā-iwi. Ka whakaratohia e ngā kaiwhakarato taputapu pono ngā tuhinga hangarau katoa, e ārahi ana i ngā kaihangarau mā te tūranga whakairi pūoko, te roa iti rawa o ngā paipa tika me ngā tikanga whakatikatika. Mā te tautoko mamao i te wā tika ka whakaitihia te wā kore mahi mō ngā wāhi tāone me ngā wāhi ahumahi.
Me whai whakaaro anō hoki ki te tiwhikete mō ngā kaupapa o te ao. Mā ngā whakaaetanga ine ine ka whakaaetia ngā raraunga rere ine mō ngā pūrongo taiao mana. Kaua e whiriwhiri i ngā mita iti te utu kāore i whakamanahia, nā te mea ka nui ake ngā mate ka puta mai i te kore whakaae kaupapa i ngā penapena taputapu tuatahi.
Hei whakarāpopototanga, ko te whakataurite i tō mita rere awa tuwhera ki tō hanganga pā wai, ki tō hanganga paipa rānei, koinei te kaupapa matua o te ine rere pono. Whakaūtia ngā kōtaha waipēhi kua hangaia, ngā āhuatanga waenga, ngā here tāutanga me ngā atanga whakawhitiwhiti e hiahiatia ana i mua i te hoko. Mena ka tohaina e koe ngā taipitopito tae atu ki te momo pā wai, te rahi o te awa, te āhuatanga waenga me te whānuitanga rere, ka taea e ngā tohunga hangarau te taunaki i te otinga mita rere awa tuwhera tino tika mō tō tono awa motuhake.
