Momwe Mungasankhire Flowmeter

Flowmeter ndi mtundu wa zida zoyesera zomwe zimagwiritsidwa ntchito kuyeza kuyenda kwamadzimadzi ndi gasi m'mafakitale ndi malo. Ma flowmeters wamba ndi electromagnetic flowmeter, misa flowmeter, turbine flowmeter, vortex flowmeter, orifice flowmeter, akupanga flowmeter. Kuthamanga kumatanthawuza liwiro lomwe madzi amadutsa papaipi, potuluka, kapena chidebe pa nthawi yoperekedwa. Oyang'anira ndi opangira zida amayezera mtengo uwu kuti ayang'anire ndikusintha liwiro ndi mphamvu zamakampani ndi zida.

Momwemo, zida zoyesera ziyenera "kukonzedwanso" nthawi ndi nthawi kuti zisawerengedwe molakwika. Komabe, chifukwa cha kukalamba kwa zida zamagetsi ndi kusokonezeka kwa coefficient, m'malo ogulitsa mafakitale, flowmeter idzayesedwa nthawi zonse kuti iwonetsetse kulondola kwa kuyeza kwake, kuti athe kugwiritsidwa ntchito mosamala komanso panthawi yake.

Kodi Flowmeter Calibrate ndi chiyani?

Flowmeter calibration ndi njira yofananizira sikelo yokhazikitsidwa kale ya flowmeter ndi sikelo yoyezera ndikusintha muyeso wake kuti ugwirizane ndi muyezo. Calibration ndi gawo lofunikira la zida m'mafakitale osiyanasiyana omwe amafunikira miyeso yolondola kwambiri, monga mafuta ndi gasi, petrochemical, ndi kupanga. M'mafakitale ena monga madzi ndi zimbudzi, chakudya ndi zakumwa, migodi ndi zitsulo, kuyeza kolondola kumafunikanso kuwonetsetsa kuti kupanga bwino.

Mamita oyenda amawunikidwa pofanizira ndikusintha ma metering awo kuti akwaniritse milingo yodziwikiratu. Opanga ma Flowmeter nthawi zambiri amayesa zinthu zawo mkati akamaliza kupanga, kapena kuzitumiza kumalo odziyimira pawokha kuti zisinthe.

Flowmeter Recalibration vs. Calibration

Flowmeter Calibration imaphatikizapo kufananiza mtengo woyezera wa flowmeter yothamanga ndi chipangizo choyezera choyezera choyenda pansi pamikhalidwe yomweyi, ndikusintha sikelo ya flowmeter kuti ikhale pafupi ndi muyezo.

Flowmeter Recalibration imaphatikizapo kuwongolera flowmeter yomwe ikugwiritsidwa ntchito kale. Kubwerezanso nthawi ndi nthawi ndikofunikira chifukwa kuwerengera kwa mita yothamanga nthawi zambiri "kuchoka" pakapita nthawi chifukwa cha kusintha kwa zinthu zomwe zimachitika m'mafakitale.

Kusiyanitsa kwakukulu pakati pa njira ziwirizi ndikuti kuwongolera koyenda kumachitidwa isanatumizidwe flowmeter kuti igwiritsidwe ntchito, pomwe kukonzanso kumachitika pakatha nthawi yayitali. Zida zamapulogalamu zitha kugwiritsidwanso ntchito kutsimikizira kulondola kwa kuyeza kwake pambuyo poti flowmeter yasinthidwa.

Momwe Mungasankhire Flowmeter

Zina mwa njira zomwe zimagwiritsidwa ntchito kwambiri poyesa ma flow meter ndi:

• Kuyesa kwa Master Meter
• Gravimetric Calibration
• Piston Prover Calibration

Njira za Master Meter Calibration

Waukulu flowmeter calibration akuyerekeza mtengo anayeza wa kuyeza flowmeter ndi mtengo muyeso wa calibrated flowmeter kapena "waukulu" flowmeter ntchito pansi chofunika otaya muyezo, ndi kusintha masanjidwe ake moyenerera. Flowmeter yayikulu nthawi zambiri imakhala chipangizo chomwe kuwongolera kwake kumayikidwa kudziko lonse kapena mayiko.

Kuti muyesere mita yayikulu:

• Lumikizani chida chachikulu muzotsatira ndi mita yothamanga yoyesedwa.
• Gwiritsani ntchito voliyumu yamadzimadzi yoyezera kuyerekeza kuwerengera kwa mita yayikulu yothamanga ndi mita yoyendera.
• Yang'anirani mita yoyendera poyesedwa kuti igwirizane ndi kuwongolera kwa mita yayikulu.

Ubwino:

• Easy ntchito, mosalekeza kuyezetsa.

Njira za Gravimetric Calibration

Kuyeza kulemera ndi imodzi mwa njira zolondola kwambiri komanso zotsika mtengo komanso zowongolera ma mita. Njira gravimetric ndi yabwino kwa ma calibration wa flowmeters madzi mu mafuta, madzi kuyeretsa ndi petrochemical mafakitale.

Kuti muyese kulemera:

• Ikani aliquot (gawo laling'ono) lamadzimadzi mu mita yoyesera ndikuyesani kwa nthawi yeniyeni pamene ikuyenda kwa masekondi 60.
• Gwiritsani ntchito sikelo yolinganizidwa kuti muyese kulemera kwa madzi oyesera.
• Nthawi yoyesera itatha, tumizani madzi oyesera ku chidebe chotsitsa.
• Kuthamanga kwa aliquot kumapezedwa pogawa kulemera kwake kwa voliyumu ndi nthawi ya mayeso.
• Yerekezerani kuchuluka kwa kuthamanga kowerengera ndi kuthamanga kwa mita yothamanga, ndipo pangani zosintha potengera kuchuluka komwe kumayesedwa.

Ubwino:

• Kulondola kwambiri (Mamita a master amagwiritsanso ntchito ma gravimetric calibration, kotero kulondola kwambiri kumakhala kochepa).

Njira za Piston Prover Calibration

Mu njira yoyezera mita ya piston calibrator, kuchuluka kwamadzimadzi kodziwika kumakanikizidwa kudzera mu mita yoyenda poyesedwa. Piston calibrator ndi chipangizo chozungulira chomwe chili ndi mainchesi odziwika amkati.

Piston calibrator ili ndi pistoni yomwe imatulutsa phokoso la voliyumu kupyolera mu kusamutsidwa kwabwino. The pisitoni calibration njira ndi abwino kwambiri kwa mkulu-mwatsatanetsatane akupanga flowmeter calibration, mafuta flowmeter ma calibration ndi turbine flowmeter calibration.

Kuti muyese piston calibrator:

• Ikani aliquot yamadzimadzi mu piston calibrator ndi ma flow mita kuti ayesedwe.
• Kuchuluka kwamadzimadzi omwe amatulutsidwa mu pisitoni calibrator amapezedwa mwa kuchulukitsa m'mimba mwake mwa pisitoni ndi kutalika komwe pisitoni imayenda.
• Yerekezerani mtengo uwu ndi mtengo woyezera womwe umapezeka kuchokera ku mita yothamanga ndikusintha kusinthasintha kwa mita yothamanga moyenerera.
