Munzvimbo dzakasiyana-siyana dzekuyera kuyerera kwemaindasitiri, uko matekinoroji akaomarara akadai semagetsi kana kuti ma ultrasonic flowmeters ari kutonga mashandisirwo makuru, ma rotameters (kana kuti float flowmeters) anoumba nzvimbo yakakosha. Midziyo iyi midiki, isingadhuri, inobudirira pakuyera kuyerera kwemvura negasi kudiki kusvika pakati, zvichipa nyore kusingaenzaniswi, nyore kushandisa, uye kuvimbika—zvichiita kuti ive chinhu chikuru mumarabhoritari, muzvivakwa zvekugadzira, uye masisitimu ekutarisa nharaunda. Kusiyana nedzimwe nzira dzetekinoroji yepamusoro dzinoda calibration yakaoma kana masosi emagetsi, ma rotameters anoshanda nepfungwa yakatwasuka yemuviri, achipa mashandiro akafanana pasina kugadziriswa kwakawanda.
Pakati pechigadzirwa che rotameter pane musimboti wenzvimbo inoshanduka, nzira iri nyore asi inoshanda inobatanidza kuyerera kwemvura nenzvimbo ye float inofambiswa. Mudziyo uyu une zvikamu zviviri zvakakosha: chubhu yakamiswa yakatwasuka, yakatetepa (inokura zvishoma kubva pasi kuenda kumusoro) uye float (kana rotor) inokwana zvisina kusimba mukati mechubhu. Kana mvura (mvura kana gasi) ichipinda muchubhu ichibva pasi, inoyerera ichikwira ichitenderedza float, zvichiita kuti pave nemusiyano wekumanikidzwa unosimudza float. Sezvo float ichikwira, nzvimbo iri pakati pe float nemadziro emukati mechubhu inowedzera—zvichideredza kumhanya kwemvura uye kumanikidzwa kukwira kunoshanda pa float. Float inozopedzisira yagadzikana pakukwirira kwakaenzana nekuyerera kwemvura: mwero wemvura yakakwira inosimudza float yakakwira, nepo mwero wemvura wakaderera uchibvumira kuti igadzikane pasi. Chikero chakagadziriswa kunze kwechubhu chinoita kuti vashandisi vaverenge zvakananga mwero wemvura zvichibva panzvimbo ye float.
Chimwe chezvakanakira zvikuru zvema "rotameters" ndechekuti zviri nyore uye mutengo wakaderera. Kusiyana nema "electromagnetic flowmeters" anoda simba uye ma "electronics" akaomarara, kana kuti ma "mass flowmeters" ane masensa system akaomarara, ma "rotameters" haana zvimwe zvinhu zvinofamba kunze kwe "float". Dhizaini iyi inoshandura kuderedza mitengo yekugadzira, zvichiita kuti ive sarudzo inodhura zvishoma yekushandisa zvinhu zvine bhajeti - senge kuyedza murabhoritari, kuyedza makemikari madiki, kana kurapwa kwemvura shoma. Pamusoro pezvo, kushaya kwavo ma "electronics" kunoreva kuti vanogona kushanda munzvimbo dziri kure kana dzisina magetsi akawanda, chinhu chakakosha pamabasa ekutarisa munda senge "environmental sampling" kana "maruwa" ekupa mvura.
MaRotameter anopenyawo zviri nyore pakuiswa nekushandiswa. Haadi mapombi akatwasuka (chinhu chinowanzo shandiswa pa turbine kana ultrasonic flowmeters) uye anogona kuiswa akatwasuka pasina kugadzika kwakawanda—zvakanakira nzvimbo dzakamanikana kana masisitimu aripo uko kugadzirisa zvinhu zvakaremara. Kuverenga zvakananga kunobvisa kudiwa kwezviratidziro zvedhijitari kana data loggers, zvichibvumira vashandi kuti vatarise mwero wekuyerera kwemvura nekukurumidza. Kune maapplication anoda kutariswa kwenguva refu, maRotameter mazhinji anogona kuve nezvinhu zvekuwedzera senge ma magnetic sensors kana ma optical detectors kuti achinje nzvimbo ye float kuita chiratidzo chemagetsi (semuenzaniso, 4-20mA) yekubatanidza nema control systems—kusanganisa nyore ne basic automation ability.
Chimwe chinhu chakakosha ndechekuti dzinoshanda zvakasiyana-siyana mumhando dzemvura. Ma "rotameters" anogona kuyera mvura (semuenzaniso, mvura, mafuta, makemikari) uye magasi (semuenzaniso, mhepo, nitrogen, gasi rechisikigo), nemagadzirirwo akagadzirirwa zvinhu zvakasiyana-siyana. Semuenzaniso, ma "glass-tube rotameters" anoshandiswa kune mvura yakajeka, isingakanganisi senge mvura kana mhepo, zvichiita kuti zvive nyore kuona zviri nyore. Ma "metal-tube rotameters" (anowanzo gadzirwa nesimbi isina ngura kana brass) akagadzirirwa mvura inoparadza, magasi ane pressure yakakwira, kana mashandisirwo ekupisa kwakanyanya—sekuyera zvinonyungudutsa zvemaindasitiri kana utsi. Zvinhu zve "float" zvinogonawo kugadziriswa: ma "PTFE float" ekudzivirira makemikari, ma "stainless steel float" ekushandiswa ne "high-pressure", kana ma "ceramic float" e "abrasive fluids"—zvichivimbisa kuti zvinoenderana nezvinodiwa zvakasiyana-siyana zvemaindasitiri.
Mukushandiswa kunoshanda, ma "rotameters" anoratidza kukosha kwawo mumaindasitiri ese. Mumarabhoritari, anoshandiswa kudzora kuyerera kwemagasi anotakura mu "gas chromatography" kana kudzora kuwedzerwa kwema "reagents" mukuyedza kwemakemikari—uko kuyerwa kwakanyatsojeka, kusingafambi zvakanaka kwakakosha. Mukugadzira, vanoongorora kuyerera kwemafuta ekuzora mumichina kana mvura inotonhorera muma "tooling fluids", vachidzivirira kukuvara kwemidziyo kubva pakuzora pasi kana kunyanyisa. Mu "environmental engineering", vanoyera kuyerera kwemakemikari mu "waste water treatment plants" (semuenzaniso, "coagulants" kana "disinfectants") kana kuyerera kwemhepo muma "emission monitoring systems"—vachitsigira kutevedzera mitemo yepamutemo.
Kunyange zvazvo marotameters aine miganhu—haana kunyatsojeka pakuyerera kwakanyanya (kazhinji anopfuura 100 m³/awa yezvinwiwa) uye anonzwa shanduko mukuwanda kwemvura kana viscosity—simba rawo rinodarika zvipingamupinyi izvi mumashandisirwo aanoita. Kune mwero wekuyerera uri pakati nepakati, uko kuri nyore, mutengo, uye kuvimbika zvinokosheswa, marotameters haasati aenzaniswa. Kufambira mberi kwemazuva ano, senge marotameters akangwara ane zviyero zvedhijitari uye kubatana kwewaya, akawedzera kushandiswa kwawo, zvichibvumira kutariswa kure uku achichengetedza zvakanakira zvawo zvikuru.
Mukupedzisa, marotameters anoratidza simba reinjiniya iri nyore. Anopa kuyerwa kwekuyerera kwakasimba uye kwakavimbika pasina kuoma kana kudhura kwetekinoroji yepamusoro, zvichiita kuti ave chishandiso chakakosha mumarabhoritari, mafekitori, uye mashandiro emumunda pasi rese. Ingave ichishandiswa pakutarisa zvinhu zviri nyore kana kuti yakabatanidzwa muhurongwa hwemagetsi, marotameters anoramba achiita basa rakakosha mukuona kuti mvura inoshandiswa zvakanaka, yakachengeteka, uye inoenderana nezvinodiwa nemaindasitiri ese.
