Mu nthawi imene kusowa kwa madzi padziko lonse lapansi komanso kukula kwa mizinda kumafuna kasamalidwe kabwino ka zinthu, njira zoyezera madzi zakale—zomwe zimadalira kwambiri zida zamakanika zomwe zimawonongeka, zosalondola, komanso kuthekera kochepa kwa deta—sizikwaniranso. Lowani mu mita yamadzi yanzeru ya ultrasonic: kusintha kwaukadaulo komwe sikungosintha momwe timayezera kagwiritsidwe ntchito ka madzi, komanso komwe kumayendetsa kusintha kwa digito kwa makampani onse oyezera madzi. Mwa kuphatikiza ukadaulo wowunikira wa ultrasonic ndi kulumikizana kwa IoT ndi kusanthula deta, zida izi zikukonzanso magwiridwe antchito, kukhazikika, komanso kutenga nawo mbali kwa ogwiritsa ntchito pa kasamalidwe ka madzi.
Mosiyana ndi makina oyezera madzi, omwe amagwiritsa ntchito magiya ozungulira kuti awerengere kayendedwe ka madzi (kapangidwe kamene kamawonongeka pakapita nthawi, zomwe zimapangitsa kuti pakhale mipata yochepa yowerengera kapena kukonza), makina oyezera madzi anzeru amagwira ntchito motsatira mfundo yosasokoneza. Amatulutsa mafunde amphamvu kwambiri kudzera mumtsinje wamadzi; poyesa kusiyana kwa nthawi pakati pa mafunde omwe akuyenda ndi kuyenda kwake, makinawo amawerengera kuchuluka kwa madzi ndi momwe amagwiritsidwira ntchito—zonse popanda kusuntha ziwalo. Ubwino waukulu uwu umachotsa zoopsa za kulephera kwa makina, kukulitsa nthawi ya mita kufika zaka 10-15 (poyerekeza ndi zaka 5-7 za makina) ndikuchepetsa ndalama zosamalira ndi 40%, malinga ndi malipoti a makampani ochokera ku International Water Association (IWA). Pazinthu zamagetsi, izi zikutanthauza kuti kuyitana kwa ntchito zochepa, ndalama zochepa zosinthira, komanso kugwira ntchito kodalirika kwa nthawi yayitali.
Koma mphamvu yeniyeni yosinthira ya ma smart ultrasonic water meter ili mu luso lawo la digito. Pokhala ndi ma IoT modules, ma smart meter awa amatumiza deta yogwiritsidwa ntchito nthawi yeniyeni ku nsanja zozikidwa pa mitambo, zomwe zimathandiza ma network ndi ogula kupeza chidziwitso patali. Pa ma network, izi zikutanthauza kasamalidwe ka madzi kosinthasintha: amatha kuzindikira kutuluka kwa madzi nthawi yeniyeni (chinthu chofunikira kwambiri, chifukwa kutayika kwa madzi padziko lonse lapansi kuchokera ku ma distributor systems kumafika pa 32%, pa World Bank) pozindikira njira zosazolowereka zoyendera—ngakhale kutuluka kwa madzi pang'ono, pang'onopang'ono komwe ma mechanical meter angaphonye. Mwachitsanzo, m'mizinda ngati Barcelona, kugwiritsa ntchito ma smart ultrasonic meter kunachepetsa madzi osapindula (madzi otayika chifukwa cha kutuluka kwa madzi kapena kuba) ndi 28% mkati mwa zaka ziwiri, kusunga mamiliyoni a ma cubic metres amadzi pachaka. Kwa ogwiritsa ntchito okhala m'nyumba ndi amalonda, kupeza deta nthawi yeniyeni kumalimbikitsa kusungidwa kwakukulu: mapulogalamu olumikizidwa ndi ma network amalola ogwiritsa ntchito kutsatira momwe amagwiritsidwira ntchito tsiku ndi tsiku, kukhazikitsa zolinga zogwiritsira ntchito, ndikulandira machenjezo a kukwera kosazolowereka—kuwapatsa mphamvu yochepetsera kuwononga ndi kuchepetsa ndalama.
Kupatula kuchita bwino komanso kusunga bwino zinthu, ma ultrasound water meter anzeru akuyala maziko ogwirizanitsa mizinda yanzeru. Pamene madera a m'mizinda akuyesetsa kukhala okhazikika, zomangamanga zamadzi ziyenera kugwirizana ndi machitidwe ena a digito—kuyambira ma gridi amagetsi mpaka kasamalidwe ka zinyalala. Ma ultrasound wanzeru amagwira ntchito ngati "ma data node" mu chilengedwe ichi: deta yawo yogwiritsidwa ntchito ikhoza kuphatikizidwa ndi kulosera kwa nyengo kuti ilosere kufunikira (monga, kuwonjezera kupezeka panthawi ya kutentha) kapena ndi machitidwe oyang'anira nyumba kuti akwaniritse bwino kugwiritsa ntchito madzi m'malo amalonda. Ku Singapore, mtsogoleri pakukula kwa mizinda yanzeru, ma ultrasound water meter ndi gawo la "Smart Water Grid" yadziko lonse, yomwe imagwiritsa ntchito deta ya mita yosonkhanitsidwa kuti iwonetse kufunikira kwa madzi m'madera osiyanasiyana, kusintha kupezeka nthawi yeniyeni, ndikukonzekera ndalama zamtsogolo pa zomangamanga. Kuphatikizika kumeneku sikunali kotheka ndi ma mechanical meter, omwe amapereka deta ya mwezi uliwonse, yowerengedwa ndi manja—yochedwa kwambiri komanso yogawanika kuti ithandizire kupanga zisankho mwachangu.
Otsutsa angazindikire kuti mtengo woyambirira wa mita yanzeru ya ultrasonic ndi wokwera kuposa njira zina zamakanika, koma phindu la nthawi yayitali limaposa chopinga ichi. Kafukufuku wa 2023 wa American Water Works Association (AWWA) adapeza kuti makampani opanga magetsi amabweza ndalama zawo mkati mwa zaka 3-5 kudzera mu kuchepa kwa kutayika kwa madzi, kuchepetsa ndalama zokonzera, komanso kubweza kolondola (kuchotsa mikangano yochokera ku zolakwika za mita yamakina). Kwa ogula, ndalama zomwe zimasungidwa chifukwa chozindikira kutayikira kwa madzi ndi kuchepa kwa kugwiritsa ntchito nthawi zambiri zimathandizira kukwera kulikonse komwe kungachitike pamalipiro a ntchito okhudzana ndi kuyika mita yanzeru.
Pamene dziko lapansi likukumana ndi mavuto ochulukirapo kuti liziyang'anira bwino madzi, makina oyezera madzi anzeru salinso "abwino kukhala nawo" koma ndi ofunikira. Sikuti amangoyesa madzi okha—akuthandiza kusintha kwa digito komwe kumapangitsa kuti kasamalidwe ka madzi kakhale kogwira mtima, kowonekera bwino, komanso kolimba. Kwa makampani akuluakulu omwe akufuna kusintha zomangamanga zawo, mizinda yomwe ikufuna kukhala yanzeru, komanso kwa ogula omwe akufuna kulamulira kagwiritsidwe ntchito kawo, makina awa ndi maziko a tsogolo la madzi lokhazikika. Paulendo wopita ku kusintha kwa digito pakuyezera madzi, ukadaulo wamagetsi wamagetsi sumangotsogolera njira—ndiwo choyambitsa kusintha.
