Flowmeter imhando yemidziyo yekuyedza inoshandiswa kuyera mafambiro emvura uye gasi mumiti yemaindasitiri nezvivakwa. Common flowmeters ari electromagnetic flowmeter, mass flowmeter, turbine flowmeter, vortex flowmeter, orifice flowmeter, Ultrasonic flowmeter. Flow rate (Flow rate) zvinoreva mamhanyiro anoita mvura papombi, muromo kana mugaba panguva yakatarwa. Kudzora uye mainjiniya ezviridzwa anoyera kukosha uku kutarisa uye kugadzirisa kumhanya uye kugona kwemaindasitiri maitiro nemidziyo.
Nenzira yakanaka, midziyo yekuedza inofanira "kugadziriswa" nguva nenguva kudzivirira kuverenga kusina kururama. Nekudaro, nekuda kwekuchembera kwezvikamu zvemagetsi uye kutsauka kweiyo coefficient, munzvimbo yeindasitiri, iyo flowmeter ichagadziriswa nguva nenguva kuti ive nechokwadi chekuyera kuyerwa, kuitira kuti ishandiswe zvakachengeteka uye nenguva.
Chii chinonzi Flowmeter Calibrate?
Flowmeter calibration inzira yekuenzanisa chiyero chakatarwa cheyekuyerera nechiyero chekuyera uye kugadzirisa kuyerwa kwayo kuti ienderane nechiyero. Calibration chinhu chakakosha chekushandisa mune dzakasiyana siyana maindasitiri anoda yakakwirira-chaiyo kuyerwa, senge mumafuta uye gasi, petrochemical, uye kugadzira. Mune mamwe maindasitiri akadai semvura netsvina, chikafu nechinwiwa, migodhi nesimbi, kuyera kwakaringana kunodiwawo kuve nechokwadi chekugadzira.
Kuyerera kwemamita anoyerwa nekuenzanisa uye kugadzirisa metering yavo kuti isangane neyakafanotsanangurwa zviyero. Vagadziri veFlowmeter vanowanzo gadzirisa zvigadzirwa zvavo mukati mushure mekugadzirwa, kana kuzvitumira kune yakazvimirira calibration zvivakwa kuti zvigadziriswe.
Flowmeter Recalibration vs. Calibration
Flowmeter Calibration inosanganisira kuenzanisa kukosha kwakayerwa kweiyo inomhanya inoyerera neicho cheyakajairwa yekuyeresa kuyerera mudziyo pasi pemamiriro akafanana, uye kugadzirisa chiyero cheiyo flowmeter kuti ive pedyo neyakajairwa.
Flowmeter Recalibration inosanganisira calibrating flowmeter iri kutoshandiswa. Periodic recalibration yakakosha nekuti kuyerera kwemamita kuverenga kunowanzo "kubuda muchikamu" nekufamba kwenguva nekuda kwekusiyana kwemamiriro ekuita mumaindasitiri.
Musiyano mukuru pakati pemaitiro maviri aya ndewekuti kuyerera kunoitwa kuyerera kusati kwatumirwa kuti ishandiswe, nepo kudzoreredza kunoitwa mushure mekunge flowmeter yave ichimhanya kwenguva yakati. Maturusi esoftware anogona kushandiswawo kuona chokwadi chechiyero mushure mekunge flowmeter yagadziriswa.
Maitiro ekugadzirisa Flowmeter
Mamwe eanonyanyo shandiswa-anonyanya kushandiswa kuyerera kwemamita calibration maitiro ndeaya:
- Master Meter Calibration
- Gravimetric Calibration
- Piston Prover Calibration
Master Meter Calibration Matanho
Iyo huru flowmeter calibration inoenzanisa kukosha kwakayerwa kweyero yakayerwa nechiyero chakayerwa che calibrated flowmeter kana "main" flowmeter inoshanda pasi peinodiwa kuyerera mwero, uye inogadzirisa kuenzana kwayo zvinoenderana. Iyo huru flowmeter inowanzova mudziyo une calibration yakatarwa kune yenyika kana yepasi rose mwero.
Kuita iyo main mita calibration:
- Batanidza chiridzwa chikuru munhevedzano nemamita ekuyerera pasi pekuedzwa.
- Shandisa yakayerwa vhoriyamu yemvura kuenzanisa kuverenga kwemahombe ekuyerera nemamita ekuyerera.
- Gadzirisa mita yekuyerera pasi pekuyedzwa kuti ienderane nekuyerwa kweiyo main flow mita.
Zvakanakira:
- Nyore kushanda, inoenderera kuyedza.
Gravimetric Calibration Matanho
Weight calibration ndeimwe yeakanyanya uye anodhura-inoshanda vhoriyamu uye misa inoyerera mita yekuenzanisa maitiro. Iyo gravimetric nzira yakanakira iyo calibration yemvura inoyerera mu petroleum, kuchenesa mvura uye petrochemical industries.
Kuita uremu calibration:
- Isa aliquot (chikamu chidiki) chemvura inoyerera muyedzo mita uye uiyere kwenguva chaiyo ichiyerera kwemasekonzi makumi matanhatu.
- Shandisa chikero chakaitwa kuti unyatsoyera huremu hwemvura yekuedza.
- Mushure mekunge nguva yekuedza yapera, tumira mvura yekuedza kumudziyo wekudhonza.
- Kuyerera kwealiquot kunowanikwa nekugovanisa huremu hwayo nenguva yekuyedzwa.
- Enzanisa chiyero chakaverengerwa chekuyerera pamwe nekuyerera kwemamita ekuyerera, uye ita zvigadziriso zvichibva pane chaiyo yakayerwa kuyerera mwero.
Zvakanakira:
- Kunyanya kurongeka (Iyo tenzi mita inoshandisawo gravimetric calibration, saka iyo yakanyanya kunaka ishoma).
Piston Prover Calibration Matanho
Muyekuyerera mita yekuenzanisa muitiro wepiston calibrator, vhoriyamu inozivikanwa yemvura inomanikidzwa kuburikidza nemamita ekuyerera pasi pekuyedzwa. Iyo piston calibrator mudziyo wecylindrical une dhayamita yemukati inozivikanwa.
Iyo piston calibrator ine piston inoburitsa vhoriyamu inoyerera kuburikidza nekutamiswa kwakanaka. Iyo piston calibration nzira yakanyatsokodzera yakakwirira-chaiyo ultrasonic flowmeter calibration, mafuta flowmeter calibration uye turbine flowmeter calibration.
Kuita piston calibrator calibrator:
- Isa aliquot yegadziriro yemvura mupiston calibrator uye kuyerera mita kuti iedzwe.
- Huwandu hwemvura inobuda mupiston calibrator inowanikwa nekuwedzera dhayamita yemukati yepiston nehurefu hunofamba nepiston.
- Enzanisa kukosha uku nechiyero chakayerwa chinowanikwa kubva pamita yekuyerera uye gadzirisa kuenzana kwemamita ekuyerera zvinoenderana.
