N’chifukwa chiyani masensa oyezera kuchuluka kwa madzi m’thupi (ultrasonic flowmeter sensors) sayenera kuyikidwa pamwamba kapena pansi pa chitoliro momwe angathere?

Poyesa kuyenda kwa madzi, chifukwa madziwo ali ndi mpweya winawake, pamene kuthamanga kwa madziwo kuli kotsika kuposa kuthamanga kwa nthunzi yokhuta ya madziwo, mpweyawo umatulutsidwa kuchokera ku madziwo kuti upange thovu lomwe limasonkhana pamwamba pa payipi, thovulo limakhudza kwambiri kuchepetsa kufalikira kwa ma ultrasound, motero limakhudza muyeso. Ndipo pansi pa payipi nthawi zambiri pamakhala zonyansa ndi matope, dzimbiri ndi zinthu zina zonyansa, zimamatira kukhoma lamkati la payipiyo, komanso zimaphimba probe ya ultrasound yomwe yayikidwa, kotero kuti mita yoyendera madzi isagwire ntchito bwino.
