Hunhu hweOpen - Channel Flowmeter muWeir kana Flume

1. Kuyera Kuyerera Kwakarurama​

• Mutangi remvura, ma "open-channel flowmeters" akagadzirwa kuyera mwero wekuyerera kwemvura nemazvo. Anowanzo shandisa musimboti wekuyera musoro (mwero wemvura) pamusoro penzvimbo chaiyo yemvura kana flume. Semuenzaniso, mu "V-notch weir", hukama huripo pakati pemwero wemvura nehuwandu hwekuyerera hunotevera fomura yemasvomhu yakanyatsotsanangurwa. Nekuyera mwero wemvura nemazvo, "flowmeter" inogona kuverenga mwero wekuyerera nemazvo. Kururama kunogona kuva mukati memapoinzi mashoma, izvo zvakakosha pamashandisirwo akadai sekutarisira zviwanikwa zvemvura, uko data rekuyerera rakarurama rinodiwa kuti mvura igoverwe uye iongororwe nemazvo.​

2. Kukodzera Mhando dzakasiyana dzeWeir neFlume​

• Ma "open-channel flowmeters" anonyatsoenderana nemhando dzakasiyana dze "weirs" ne "flumes". Ingave iri "rectangular weir", "triangular weir", kana "Parshall flume", "flowmeter" inogona kugadzirwa kuti ishande zvinobudirira. Mhando dzakasiyana dze "weir" ne "flume" dzine hunhu hwadzo hwe "hydraulic", uye "open-channel flowmeter" inogona kuenzaniswa uye kurongwa kuti iongorore misiyano iyi. Semuenzaniso, "Parshall flume" inowanzo shandiswa mumamiriro ezvinhu apo "flow rate" inoda kuyerwa munzvimbo dzakasiyana-siyana. "Open-channel flowmeter" inogona kugadziriswa kuti ione kuyerera kwemvura kuburikidza ne "Parshall flume" nemazvo, zvisinei nekuti "flow" iri pa "low" kana kuti "high".​

3. Kuisa Kusingapindire​

• Kuisa ma "open-channel flowmeters" mumatangi e "weir" kazhinji hakupindi mvura. Mazhinji ema "flowmeters" aya anoshandisa ma "sensors" akaiswa pamusoro kana pedyo ne "weir" kana "flume", pasina chikonzero chekukanganisa kuyerera kwemvura. Semuenzaniso, ma "ultrasonic level sensors" anowanzo shandiswa. Anoiswa pamusoro pemvura iri mutangi re "weir" uye anoyera daro kubva pamusoro pemvura. Nzira iyi yekuisa isingapindi mvura inoderedza kukanganiswa kwemvura iri mutangi re "weir", uye zvakare inorerutsa maitiro ekuisa. Hapana chikonzero chekumisa kuyerera kwemvura panguva yekuisa, izvo zviri nyore kwazvo kune masisitimu anoshanda nguva dzose akadai se "water treatment plants".​

4. Kuvimbika Munzvimbo Dzine Hukasha​

• Matangi emvura anowanzo kuwanikwa munzvimbo dzekunze kana dzemaindasitiri uko mamiriro ezvinhu anogona kuoma. Ma "flowmeters" akavhurika akagadzirwa kuti ave akavimbika munzvimbo dzakadaro. Anowanzo gadzirwa nezvinhu zvinogara kwenguva refu zvinogona kutsungirira mvura, hunyoro, uye kuchinja kwekupisa. Pamusoro pezvo, masensa anoshandiswa mu "flowmeters" aya anowanzo dzivirirwa kubva pakukanganiswa nezvinhu zvekunze zvakaita semagetsi. Semuenzaniso, mu "remota" yekuchenesa mvura yakasviba, uko kungave nemidziyo yakawanda yemagetsi iri kushanda pedyo, "flowmeter" yakavhurika inogona kushanda zvakanaka uye nemazvo kuyera kuyerera kwemvura yakasviba mu "weir tank".​

5. Kutarisa Kure uye Kutumira Data​

• Michina yemazuva ano yekuyerera kwemvura yakavhurika mumatangi emvura yakavhurika ine kugona kwekutarisa uye kutumira data kure. Inogona kubatanidzwa kune system yekudzora iri pakati nepakati kuburikidza nenzira dzekutaurirana dzine waya kana dzisina waya. Izvi zvinobvumira vashandisi kutarisa mwero wekuyerera kwemvura mutangi remvura munguva chaiyo kubva kunzvimbo iri kure. Semuenzaniso, mune system yekudiridza yakakura ine matangi akawanda emvura yakavhurika munzvimbo yakakura, data rekuyerera kwemvura kubva kune imwe neimwe chiteshi chemvura yakavhurika rinogona kutumirwa kukamuri rekudzora repakati. Vashandi vanogona kuongorora data, kugadzirisa system yekugovera mvura sezvinodiwa, uye kuona kuti mvura inoshandiswa zvakanaka.
