Kuyera kuyererandiyo nzira huru yekugovera mvura yemumaguta, kugadzirisa mvura yakasviba, kugadzira migodhi uye kugadzira makemikari. Mita yekuyerera yemukati memagetsi yakadai seyemagetsi neturbine inosangana nematambudziko ari pachena pakuyera zvinwiwa zvine zvinhu zvakasimba zvakasungirirwa, tsvina kana mabubble emhepo: maelectrode emukati anosakara nyore nyore, maimpeller anovharika, uye kuchekwa kwepombi nekuvharwa kwekugadzira zvinosungirwa panguva yekuisa. Iyo clamp-on Doppler ultrasonic flow meter inogadzirisa nzvimbo idzi dzekurwadziwa zvakakwana nekushandisa installing yekunze isingapindi uyeMhedzisiro yeDopplerdzidziso, ichiva chinhu chinoyerwa chinodiwa pamapaipi akaomarara nemarara pasi rose.
Pfungwa huru yekushanda kwema clamp-on Doppler flow meter inobva kuDoppler Effect yakawanikwa nenyanzvi yefizikisi Christian Doppler. Midziyo iyi inoumbwa neyuniti yekuratidza host uye ma transducer ekunze e ultrasonic akasungirirwa pamadziro epombi yekunze ane ma clamps. Transducer imwe inoburitsa mwenje we ultrasonic we high-frequency wakaomerera mumvura iri mukati mepombi. Sezvo kuyerwa kweDoppler kuchida ma acoustic reflectors, chiratidzo che ultrasonic chinosvetuka kubva pazvikamu zvakasimba zvakasungirirwa kana mabubble emhepo madiki achifamba pamwe chete nekuyerera kwemvura. Kufamba pakati pema reflectors nema sensors kunoita kuti pave nekuchinja kwefrequency pakati pema transmissions neanogamuchira sound waves. Microprocessor yakavakwa mukati inoverenga real-time fluid velocity zvichibva pamusiyano wefrequency, yobva yasanganisa input pipe outer diameter, wall thickness uye material parameters kuti ibudise instantaneous flow velocity uye cumulative volumetric flow.
Chimwe chinhu chakanaka chemita iyi ndechekuti haina kupindira zvachose. Kusiyana nezvishandiso zviri mukati, ma transducer haambobatani nemidziyo yakayerwa. Vashandi vanogona kupedzisa kuisa mukati memaminitsi gumi vasina kucheka mapaipi, kubvisa mvura kana kumisa kushanda kwefekitori nemvura, izvo zvinoderedza zvakanyanya mari yekuvaka nenguva yekushanda. Hapana kurasikirwa nekumanikidzwa mupaipi, hapana njodzi yekubuda kwemvura pakati nepakati, uye hapana zvinhu zvakanyorova kuti zvikanganise kana kusvibisa. Kune mapaipi ane dhayamita hombe pamusoro peDN500, ma clamp-on Doppler metres ane mari shoma yekutenga nekuisa kupfuura electromagnetic.mita dzekuyerera, zvichiratidza mabhenefiti makuru ehupfumi mumapaipi makuru emvura uye masisitimu emvura anotenderera mumaindasitiri.
Chishandiso ichi chine simba rekugadzirisa zvinhu zviri pakati nepakati uye chinopa hunyanzvi hwakakura. Chinoyera mvura ine zvinhu zvinodarika 100 mg/L zvakasungirirwa kana mabhurumu madiki, zvinofukidza tsvina, tsvina yakabatidzwa, pulp yekuchera, doro rakasanganiswa nemakemikari nemvura yakasviba yemumaindasitiri ine mhepo. Chinokodzera zvinhu zvese zvepaipi zvinosanganisira simbi yekabhoni, simbi isingatsvedzeri, simbi yakakandwa, PVC nefiberglass, zvichitsigira dhayamita dzepaipi kubva kuDN40 kusvika kuDN3000. Mhando dzemazuva ano dzinopa huwandu hwakakura hwekuchinja hunobva paR250 kusvika kuR500, hunokwanisa kubata kuyerera kudiki uye kuyerera kwepamusoro pasina kushandura michina. Sarudzo dzakapfuma dze telemetry dzakadai seLoRaWAN, NB-IoT neGPRS dzakabatanidzwa pakurodha data kure, kufananidza smart aqueduct network DMA zoning metering, kutarisa kuyerera kwepipeline uye zvinodiwa zvekutarisira nzvimbo yemvura yakasviba zvisina kutarisirwa.
Mari shoma yekugadzirisa ndeimwe yemakwikwi. Pasina zvikamu zvemukati zvinofamba, kuchenesa nguva dzose kana kutsiva maerekitirodhi hazvina basa, kusiyana nemaerekitirodhi emagetsi anoda kugadziriswa mwedzi wega wega mumapaipi etsvina. Vashandisi vanongoda kutarisa mamiriro ekugadzirisa transducer uye kuzadza ultrasonic coupling agent kamwe chete pamwedzi mitanhatu yega yega. MaDoppler anotakurika anowanikwawo kuti aongorore kuyerera kwenguva pfupi, kuyedzwa kwekushanda kwepombi uye kuongororwa kwemapaipi pasina kuiswa zvachose.
Pasinei nehuwandu hwekushandiswa kwayo hwakakura, vashandisi vanofanirwa kutevedzera zvinodiwa zvekusarudza:Mamita eDopplerHazvina kukodzera mvura yakachena kwazvo isina zvidimbu zvakakwana kuti iratidze masaini e ultrasonic, uko ma ultrasound meters e clamp-on clamp-on ari sarudzo iri nani. Vanoisa vanofanira kuchengetedza zvikamu zvakakwana zvemapombi akatwasuka vasati vasvika uye vapedza masensa, vachidzivirira nzvimbo dziri pedyo nemagokora, mavharuvhu nemapombi kuti vave nechokwadi chekuti mvura inoyerera zvakanaka uye kuti kuyera kwacho kwakarurama nguva dzose.
Munguva yekutarisira mvura kwakangwara uye IoT yemaindasitiri,mita dzekuyerera kweDoppler dzinoshandiswa pa clamp-onKuzadza mukaha wekutarisa kuyerera kwemvura kwakaderera uye kusingamiri kwemapaipi ane tsvina. Kusanganiswa kwayo kuri nyore kuisa, kusakuvara kwepaipi, kugara kwenguva refu uye mabasa akasiyana-siyana ekutaurirana ari kure kunoita kuti ive chishandiso chisingatsiviwi chekuyera network dzemuguta, nzvimbo dzekuchenesa mvura yakasviba uye maindasitiri emigodhi. Sezvo kugadziriswa kwemapaipi nekuvakwa kwenetiweki yemvura yedhijitari kuri kuwedzera pasi rose, kudiwa kwemusika kwemamita ekuyerera kweDoppler anodzivirira kucharamba kuchikura mumakore gumi anotevera.
