1) Electromagnetic flowmeter imafuna chitoliro chowongoka chomwe ndi chachifupi kuposa cha akupanga flowmeter.Electromagnetic flowmeter unsembe malo sangakhalenso molunjika chitoliro, kotero yerekezerani pa zochitika, kulabadira udindo wa kuyeza ngati angathe kukwaniritsa zowongoka chitoliro akupanga flowmeter, ngati si kukumana chitoliro molunjika ayenera kukhala pafupi kusankha zikugwirizana ndi udindo wa muyeso wa ultrasonic flowmeter, kuyerekeza zotsatira sizingakhale zolondola.
2) Onani ngati kuyika kwa electromagnetic flowmeter kumakwaniritsa zofunikira zamadzimadzi (monga ma conductivity amadzimadzi, ngati kuyika kuli m'munsi mwa payipi, ngati thovu likhoza kuwunjikana, ndi zina).Ngati sichoncho, ziyenera kuperekedwa kwa wogwiritsa ntchito kuti izi zitha kukhala zomwe zayambitsa vutoli.
3) Electromagnetic flowmeter ndi chida chabwino choyezera kuthamanga kwamadzimadzi oyendetsa.Kulondola kwa kuyeza kwake ndikokwera kwambiri, nthawi zambiri ku 0.5%, ndipo ndikwabwino kufikira 0.2%.Nthawi yomweyo, chidwi chiyenera kuperekedwa kwa wopanga ma electromagnetic flowmeter.Ngati malonda amtunduwo aikidwa popanda cholakwika ndipo ma conductivity amadzimadzi akukwaniritsa zofunikira, muyeso woyezera uyenera kuganiziridwa mosamala, pomwe opanga omwe si amtundu uliwonse, malinga ndi kukhazikika kwa mtengo wamagetsi ndi kukula kwa zolakwika, mutha kukhala olimba mtima kukayikira.
4) Kumvetsetsa momwe payipi ikuyendera, kaya pali mzere, makulitsidwe ndi zochitika zina komanso magawo okhudzana ndi payipi kuchokera kwa wogwiritsa ntchito.Pulitsani mapaipi mukakhazikitsa sensa ya akupanga, ndipo sankhani njira ya Z yoyezera ndikuyerekeza momwe mungathere.
5) Madzi omwe angayesedwe ndi akupanga flowmeter samakhudzidwa ndi conductivity.Ngati mtengo wa akupanga ndi wokhazikika pamene mphamvu yamagetsi imakhala yosasunthika poyerekezera, zimasonyeza kuti ma conductivity a otaya thupi anayeza ali m'malire boma index, osati chifukwa cha madzimadzi munali mpweya, ndi mtengo wa akupanga. flowmeter ndi yodalirika.Ngati zonse sizikhazikika nthawi imodzi, kuthekera kwa thovu kumakhala kwakukulu.
6) Zofunikira za electromagnetic flowmeter kuti ziyezedwe zamadzimadzi ziyenera kukhala zofanana ndi dziko lapansi, apo ayi padzakhala muyeso wamphamvu wosokoneza, ndiye ngati mazikowo ali olakwika kapena oyipa (malo amagetsi ali ndi zovuta komanso zofunikira), padzakhala zovuta. , ayenera kuyang'ana mkhalidwe wapansi.Poyerekeza ndi akupanga flowmeter, palibe kuthekera chofunika madzi.Ngati grounding ndi zokayikitsa, mtengo akupanga flowmeter ndi zolondola.
7) Ngati pali kusokonezedwa magetsi ndi maginito minda pafupi, chikoka cha akupanga flowmeter ndi zosakwana kuti a electromagnetic flowmeter, ndi kudalirika kwa akupanga anasonyeza mtengo ayenera kukhala wamkulu kuposa maginito flowmeter.
8) Ngati pali phokoso losokoneza paipi (monga phokoso lopangidwa ndi valavu yaikulu yoyendetsa magetsi), mphamvu ya akupanga ndi yaikulu kwambiri kuposa ya electromagnetic, ndipo kudalirika kwa chizindikiro cha electromagnetic ndi kwakukulu kuposa pamenepo. wa ultrasonic.
