He taputapu whānui te whakamahi i te Parshall Flume Flow Mita, ā, he taputapu pono hoki mō te ine i te rere o te wai i roto i ngā awaawa tuwhera. Engari me pēhea tana mahi? Me ruku tātou ki ngā āhuatanga o tēnei taputapu nui, kia mārama ai ki tana mahi.
Ko te mahi a ngā mita rere o te awa Parshall he mea hanga ki te kaupapa o te whakaheke me te rerekētanga pēhanga. He hanganga awa tuwhera motuhake tōna e whaiti ana i te korokoro, kātahi ka whānui anō. Mā tēnei hoahoa ahurei ka taea e te awa te hanga i ngā tauira rere motuhake, e taea ai te ine tika i te rere o te wai.
I te rere o te wai mā roto i te totohu, ka tere ake i a ia e haere ana mā roto i te korokoro nā te whakahekenga. Nā tēnei tere ka heke te pēhanga, ka inehia mā te whakamahi i tētahi pūoko pēhanga kei te korokoro o te tāke. Ko te rerekētanga pēhanga i waenga i ngā wāhanga whakarunga me ngā wāhanga whakararo o te awaawa he rite ki te tere rere o te wai.
Kātahi ka tatauhia te tere rere mā te whakamahi i te whārite a Bernoulli, e hono ana i te rerekētanga pēhanga ki te tere o te wai e rere ana. Mā te ine tika i te pēhanga rerekētanga, ka taea e ngā mita rere o te awa Parshall te whakarato i ngā pānui rere tika, ka waiho hei taputapu whai hua i roto i ngā momo tono tae atu ki ngā tipu maimoatanga wai para, ngā pūnaha whakamakuku, me te aroturuki taiao.
Ko tētahi o ngā painga matua o te mita rere o te awa Parshall ko tōna kaha ki te whakahaere i te whānuitanga o ngā tere rere. Mā te hoahoa o te awa ka taea te ine tika i ngā tere rere iti me te tere rere teitei, e pai ai mō ngā āhuatanga waipēhi rerekē. Hei tāpiri, ko ngā āhuatanga horoi-ake o te totohu me te ātete ki te aukati ka whakarite kia pono, kia tonu te mahi ahakoa i roto i ngā taiao uaua.
He tino māmā te tāuta me te tiaki i ngā mita rere o te Parshall flume, ā, he mea nui anō hoki tēnei kia tika ai te tāutanga kia tika ai ngā inenga, ā, he mea nui hoki te tirotiro me te horoi auau kia kore ai e pāngia tōna mahi.
Haunga ōna mahi, e mōhiotia ana hoki ngā mita rere o te awa Parshall mō tōna utu iti. He otinga pono, he tika hoki ngā awa i te utu iti ki te whakatauritea ki ētahi atu taputapu ine rere, ā, koinei te whiringa tuatahi mō te maha o ngā ahumahi me ngā tono.
Hei tāpiritanga, nā ngā whanaketanga hangarau kua arahina ki te whakaurunga o ngā pūoko hiko me ngā āheinga takiuru raraunga, e āhei ai te aroturuki wā-tūturu me te urunga raraunga mamao. Ehara i te mea ka whakapai ake i te tika o ngā inenga rere anake, engari ka whakangāwari ake hoki i te tukanga kohikohi raraunga, ka whakarato i ngā māramatanga whai hua mō te arotau i te tukanga me te whakatau kaupapa.
Hei whakarāpopototanga, he taputapu nui te Parshall Flume Flow Meter mō te ine tika i te rere o te wai i roto i ngā awa tuwhera. Nā tōna hoahoa ahurei, te mahi pono me te utu iti, koinei te whiringa tuatahi mō te whānuitanga o ngā tono. He mea nui te mārama ki ngā āheinga o tēnei taputapu nui hei whakarite i te ine tika o te rere me te arotau i ngā tukanga whakahaere wai.
