Muchikamu chekuyera nemazvo maitiro emaindasitiri, mamirimita ekuyerera kwehuwandu (MFMs) ave mudziyo unokosha, unozivikanwa zvikuru nekukwanisa kwawo kuyera zvakananga mwero wekuyerera kwehuwandu hwemvura pasina kukanganiswa nekuchinja kwekupisa, kumanikidzwa, kana density. Kusiyana nemamirimita ekuyerera kwehuwandu anongoyera huwandu uye anoda kugadziriswa kunotevera, mamirimita ekuyerera kwehuwandu anopa data rakarurama uye rakavimbika rekuyerera kwehuwandu, iro rakakosha pakugadzirisa mashandiro ehurongwa, kuona kuti chigadzirwa chakanaka, uye kuderedza marara ezviwanikwa. Chinyorwa chino chinoongorora zvakanakira zvikuru, mashandisirwo akasiyana-siyana emaindasitiri, zvinodiwa zvakakosha pakusarudza, uye maitiro ekuvandudza ehukuru hwehuwandu, zvichiratidza basa rawo rinokosha mukugadzirwa kwemaindasitiri kwemazuva ano uye kudzora maitiro.
Chimwe chezvakanakira zvikuru zvemamita ekuyerera kwehuwandu ndiko kugona kwawo kuyera huwandu hwakananga uye hwakanyatsojeka. Nekuyera zvakananga huwandu hwemvura inopfuura nemumita panguva imwe neimwe, vanobvisa zvikanganiso zvekuyera zvinokonzerwa nekuchinja-chinja kwehunhu hwemvura (senge tembiricha nekumanikidzwa) zvinobata mamita ekuyerera kwehuwandu. Hunhu uhwu hunoita kuti zvive zvakakodzera zvakanyanya kune maitiro anoda kudzora huwandu hwemvura, senge makemikari, kupisa mafuta, uye kugadzirwa kwemishonga. Kururama kwekuyera kwemamita ekuyerera kwehuwandu hwepamusoro kunogona kusvika ±0.1% yehukuru hwakazara, zvichiita kuti zvive nechokwadi chekuti parameter dzemaitiro dzakagadzikana uye dzinoenderana, izvo zvakakosha pakuvandudza mwero wekukodzera kwechigadzirwa uye kuderedza mari yekugadzira.
Chimwe chinhu chakakosha chema "mass flow meter" ndechekuti anokwanisa kuchinjika zvakanyanya kumarudzi akasiyana emvura nemamiriro ekushanda. Anogona kuyera magasi, mvura, uye kunyange mvura ine zvikamu zvakawanda (senge gas-liquid mixes), zvichifukidza huwandu hwakakura hwe "viscosity" uye "density ranges". Semuenzaniso, ma "thermal mass flow meter" akakodzera kuyera magasi ane low-pressure, nepo Coriolis mass flow meter achinyanya kuyera ma "high-viscosity liquids" uye "corrosive media". Pamusoro pezvo, ma "mass flow meter" anoshanda zvakanaka munzvimbo dzakanyanya kupisa uye dzakamanikidzwa - kubva kuma "high-temperature industrial ovens" kusvika kuma "low-temperature cryogenic systems" - zvichiita kuti akwanise kushandiswa munzvimbo dzakasiyana-siyana dzeindasitiri, kusanganisira petrochemical, aerospace, uye food processing.
Mashandisirwo emamita ekuyerera kwehuwandu hwezvinhu anoshandisa zvikamu zvakawanda zvemaindasitiri, zvichiratidza kushanduka-shanduka kwadzo uye kukosha kwadzo. Muindasitiri yemafuta, mita dzekuyerera kwehuwandu hwezvinhu zveCoriolis dzinoshandiswa zvakanyanya mukubvisa, kunatsa, uye kutakurwa kwezvinhu. Dzinoyera nemazvo kufamba kwehuwandu hwezvinhu zvemafuta asina kucheneswa, peturu, dhiziri, nezvimwe zvigadzirwa zvepeturu, zvichiita kuti zvinhu zvitarisirwe zvakanaka uye kutengeserana kwakakodzera kugadzirwe. Muindasitiri yemakemikari, mita dzekuyerera kwehuwandu hwezvinhu zvine chekuita nemakemikari dzinoita basa rakakosha mukuita kwemakemikari nekudzora zvakakwana mwero wekudya kwezvinhu zvakacheneswa, kuona kuti chiyero che stoichiometric che reactants chiripo, uye nekudaro zvichivandudza kushanda kwemhinduro uye mhando yezvigadzirwa. Semuenzaniso, mukugadzirwa kwepolyethylene, kuyerwa kwakarurama kwehuwandu hwe ethylene ne comonomer kwakakosha pakudzora huremu hwemamorekuru uye mashandiro echigadzirwa chekupedzisira.
Mumaindasitiri emishonga nezvekudya, mita dzekuyerera kwemafuta dzinosangana nezvinodiwa zvehutsanana uye nemazvo. Mata ekuyerera kwemafuta eCoriolis ane nzvimbo dzakapfava uye dziri nyore kuchenesa anoshandiswa kuyera kuyerera kwezvinoshandiswa mumishonga, mafuta anodyiwa, uye zvigadzirwa zvemukaka, zvichiona kuchena kwechigadzirwa uye kutevedzera mitemo. Muchikamu chesimba, mita dzekuyerera kwemafuta ekupisa dzinoshandiswa kuyera kuyerera kwegasi rechisikigo, biogas, nemamwe mafuta mumagetsi ekugadzira nekudziyisa, zvichivandudza kushanda kwemoto uye kuderedza kuburitswa kwegasi rinopisa. Pamusoro pezvo, muindasitiri yesemiconductor, mita dzekuyerera kwemafuta dzinodzora kuyerera kwemagasi eprocess (akadai senitrogen, oxygen, uye argon) panguva yekugadzira chip, zvichiona kunaka uye goho rezvigadzirwa zvesemiconductor.
Kusarudza mita yekuyerera kwehuwandu yakakodzera kunoda kunyatsofungisisa zvinhu zvakakosha kuti uve nechokwadi chekuti inoshanda zvakanaka. Chekutanga, mhando yemita yekuyerera kwehuwandu inofanirwa kuenderana nerudzi rwemvura uye zvinodiwa pakuyera: mita yekuyerera kwehuwandu hwemafuta akakodzera kuyerwa kwegasi, nepo mita yekuyerera kwehuwandu hwemafuta eCoriolis ichinyanya kusarudzwa pakushandiswa kwemvura uye mashandisirwo ehuwandu hwemafuta. Chechipiri, huwandu hwekuyera hunofanira kufukidza mwero wekuyerera wepasi uye wepamusoro unotarisirwa, uye chiyero chemita yekudzora (kazhinji 100:1 kana kupfuura kune mamodheru anoshanda zvakanyanya) chinofanira kukwana kubata kushanduka kwekuyerera. Kusarudzwa kwezvinhu kwakakoshawo - simbi dzakadai sesimbi isingatsvedzeri neHastelloy dzakakodzera ngura, nepo zvinhu zvehutsanana (senge 316L simbi isingatsvedzeri) zvichidikanwa pakushandiswa kwechikafu nemishonga. Pamusoro pezvo, nzvimbo dzekutaurirana (dzakadai seHART, RS485, uye Ethernet) dzinofanira kuenderana nehurongwa huripo hwekudzora maitiro kuti zvigone kubatanidza data zvakanaka uye kutarisa kure.
Nekufambira mberi kwekushandiswa kwedhijitari mumaindasitiri uye Internet of Things (IoT), mass flow metres ari kushanduka achienda kuhungwaru nekubatana. Ma mass flow metres emazuva ano ane hunyanzvi hwepamusoro hwekugadzirisa masaini edhijitari, zvichigonesa kuongorora data panguva chaiyo uye mabasa ekuzviongorora. Mabasa aya anogona kuona matambudziko angangoitika akadai sekusvibiswa kwemasensa, kupindira kwemasaini, uye kutadza kushanda zvakanaka kwemidziyo, zvichipa yambiro panguva yakakodzera kuderedza nguva isina kurongwa yekushanda. Uyezve, kubatanidzwa kwetekinoroji dzekutaurirana dzisina waya (dzakadai seLoRa neNB-IoT) kunobvumira kutarisa kure uye kugadzirisa maparameter, kuderedza mari yekushanda nekuchengetedza panzvimbo. Mamwe mamodheru epamusoro anotobatanidza maalgorithms ehungwaru hwekugadzira (AI) kufanotaura mafambiro emafambiro uye kugadzirisa ma process parameters, zvichiwedzera kuwedzera kushanda zvakanaka uye kubereka.
Mukupedzisa, mita dzemagetsi dzinoyerera zvakanyanya dzave musimboti wekudzora mashandiro emazuva ano emaindasitiri, zvichipa kuyera kwakananga, kwakanyatsojeka uye kugona kuchinjika kwakasiyana-siyana muzvikamu zvakasiyana-siyana. Kugona kwavo kuve nechokwadi chekugadzikana kwemaitiro, kuvandudza mhando yechigadzirwa, uye kuderedza kushandiswa kwezviwanikwa kunoita kuti zvive zvakakosha kumaindasitiri ari kuedza kushanda zvakanaka uye kugadzikana. Sezvo otomatiki yemaindasitiri uye digitalization zvichiramba zvichiwedzera, mita dzemagetsi dzinoyerera zvakanyanya dzicharamba dzichibatanidza matekinoroji epamusoro, dzichipa mhinduro dzekuyera dzakangwara uye dzakavimbika kuti dzisangane nezvinodiwa zviri kuchinja zveindasitiri yepasi rose.
