1. Isignali yokuphuma kwe-electromagnetic flowmeter incane kakhulu, imvamisa ingama-milivolti ambalwa kuphela. Ukuze kuthuthukiswe ikhono lokulwa nokuphazamiseka kwethuluzi, amandla anguziro kumjikelezo yokokufaka kumele abe yiziro namandla aphansi, okuyisimo esanele sokuthi inzwa imiswe phansi. Ukuphansi phansi okungalungile noma ukungabi khona kwentambo yaphansi kuzodala amasignali okuphazamisa angaphandle futhi ayikwazi ukukalwa ngokujwayelekile.
2. Indawo okusekelwe kuyo inzwa kagesi kufanele ixhunywe endaweni elinganisiwe, okuyisimo esidingekayo ukuze i-flowmeter kagesi isebenze. Uma lesi simo singahlangatshezwana nayo, i-flowmeter ye-electromagnetic ayikwazi ukusebenza ngokujwayelekile, enqunywa umjikelezo wesiginali wenzwa. Lapho uketshezi lusika intambo kazibuthe ukuze kukhiqizwe isignali yokugeleza, uketshezi ngokwalo lusebenza njengamandla aziro, i-electrode eyodwa ikhiqiza amandla amahle, enye i-electrode ikhiqiza amandla angalungile, futhi ishintsha ngokushintshana. Ngakho-ke, indawo emaphakathi yokokufaka kwesiguquli (isivikelo sekhebula lesiginali) kumele sibe ku-zero futhi ihambisane noketshezi ukuze kwakheke isekethe yokufaka elinganayo. Iphoyinti eliphakathi nendawo yokugcina okokufaka yesiguquli lixhunywe ngogesi kuketshezi olulinganisiwe ngephoyinti eliphansi lesignali yokuphuma kwenzwa.
3. Ngempahla yamapayipi ensimbi, ukuphansi okuvamile kungenza imitha yokugeleza isebenze ngokujwayelekile. Ukuze uthole impahla ekhethekile yamapayipi ngokwesibonelo impahla ye-PVC, imitha yokugeleza kuka-electromagnetic kufanele ibe nendandatho yaphansi ukuze uqiniseke ukuthi umthombo ophansi kanye nomsebenzi ojwayelekile wemitha yokugeleza.
