1) I-electromagnetic flowmeter ifuna umbhobho othe ngqo mfutshane kune-ultrasonic flowmeter's.Indawo yofakelo lwe-electromagnetic flowmeter indawo yofakelo ayinakuba ngumbhobho othe tye, ke thelekisa kwindawo yexhwayelo, nikela ingqalelo kwindawo yokulinganisa ukuba inokufikelela na kwiimfuno zombhobho othe ngqo we-ultrasonic flowmeter, ukuba ayihlangabezani nombhobho othe tye kufuneka ube kufutshane, khetha ihambelane nesikhundla Umlinganiselo we-flowmeter ye-ultrasonic, uthelekiso iziphumo aziyi kuba zichanekile.
2) Jonga ukuba indawo yofakelo lwe-electromagnetic flowmeter iyahlangabezana neemfuno zokuqukuqela kolwelo (ezifana nokuqhutywa kolwelo, nokuba ufakelo lukwindawo esezantsi yombhobho, nokuba amaqamza angaqokelelana, njl. njl.).Ukuba akunjalo, kufuneka kucetywe kumsebenzisi ukuba oku kunokuba ngunobangela wengxaki.
3) I-Electromagnetic flowmeter sisixhobo esilungileyo sokulinganisa ukuhamba kolwelo oluqhubayo.Ukuchaneka kokulinganisa kwayo kuphezulu kakhulu, ngokubanzi kwi-0.5%, kwaye kungcono ukufikelela kwi-0.2%.Ngelo xesha, ingqalelo kufuneka ihlawulwe kumenzi we-electromagnetic flowmeter.Ukuba imveliso ye-brand ifakwe ngaphandle kwempazamo kwaye i-conductivity yolwelo iyahlangabezana neemfuno, ixabiso lokulinganisa kufuneka likrokrelwe ngononophelo, ngelixa kubavelisi abangabalulekanga, ngokwexabiso le-electromagnetic field uzinzo kunye nobukhulu bempazamo, unokuba nesibindi sokungathandabuzeki.
4) Qonda imeko yesixhobo sombhobho, nokuba kukho i-lining, ukulinganisa kunye nezinye izinto kunye neeparitha ezinxulumene nombhobho osuka kumsebenzisi.Gcoba umbhobho xa ufaka inzwa ye-ultrasonic, kwaye ukhethe indlela ye-Z yokulinganisa kunye nokuthelekisa kangangoko kunokwenzeka.
5) I-liquid enokuthi ilinganiswe yi-flowmeter ye-ultrasonic ayichaphazeleki yi-conductivity.Ukuba ixabiso le-ultrasonic lizinzile ngelixa ixabiso le-electromagnetic lizinzile ngexesha lokuthelekisa, libonisa ukuba i-conductivity ye-flow body elinganiswayo ikwimeko yomda wesalathisi, kunokuba ibangelwa yi-fluid equkethe igesi, kunye nexabiso le-ultrasonic. I-flowmeter ithembekile.Ukuba zombini azinzanga ngaxeshanye, ukubakho kwamaqamza kukhulu.
6) Iimfuno zemitha ye-electromagnetic flowmeter ukuze kulinganiswe ulwelo kufuneka zibe namandla alinganayo kunye nomhlaba, kungenjalo kuya kubakho umlinganiso oqinileyo wokuphazamiseka, ke xa isiseko singalunganga okanye singalunganga (isiseko sombane sineemfuno ezintsonkothileyo nezingqongqo), kuya kubakho iingxaki. , kufuneka ihlole imeko yokumisa.Xa kuthelekiswa ne-flowmeter ye-ultrasonic, akukho mfuneko enokwenzeka yolwelo.Ukuba i-grounding iyabuza, ixabiso le-flowmeter ye-ultrasonic ichanekile.
7) Ukuba kukho ukuphazamiseka kombane kunye nemimandla yamagnetic ekufutshane, impembelelo ye-flowmeter ye-ultrasonic ingaphantsi kwe-electromagnetic flowmeter, kwaye ukuthembeka kwexabiso lokubonisa i-ultrasonic kufuneka libe likhulu kunolo lwe-electromagnetic flowmeter.
8) Ukuba kukho umthombo wesandi ophazamisayo kumbhobho (onjengesandi esiveliswa yivalve enkulu elawula uxinzelelo), impembelelo kwi-ultrasonic inkulu kakhulu kunaleyo ye-electromagnetic, kwaye ukuthembeka kwexabiso lesalathiso sombane kukhulu kunoko. ye ultrasonic.
