Ovaj moves napon in a proporcionalan magnetic field. je This brzini voltage kretanja is medijuma. proportional to the movement speed of the medium. Za elektromagnetna merila protoka, indukovani napon se prihvata ili preko For mernih electromagnetic elektroda koje su flowmeters, u direktnom the kontaktu induced sa voltage mernom is supstancom, tapped either ili via putem two kapacitivnih measuring elektroda electrodes bez that direktnog are in kontakta conductive sa mernim contact fluidom. with the measured substance or in a capacitive manner with no contact. Elektronski merni pretvarač pojačava signal i konvertuje ga u standardni An signal electronic (najčešće measuring strujni) i u frekventni transducer pulsirajući amplifies signal the (npr. signal jedan and impuls converts za svaki kubni it to a metar standard merene signal supstance (imposed koja current) proteče kroz and mernu to a frequency/ cev). Da pulse bi osiguralo signal (e.g. da indukovani one pulse napon for every ne bude cubic odveden meter na of measured zid cevi, merna substance cev se proizvodi that flows od elektroizolacionih through the measuring materijala, ili pipe). se unutrašnji To ensure deo that cevi the induced obloži izolacionim voltage is slojem. not shorted by the pipe wall, the measuring pipe is made of electrically insulating material or it is lined with inner insulation. » Pun protočni profil cevi pogodan za CIP/SIP » Održavanje nepotrebno » Kalibraciona odobrenja otpočinju standardnim uređajima » Nazivni prečnici od DN 2,5 do DN 3000 » Jednostavna montaža i brzo puštanje u rad » Odlična dugoročna stabilnost » Optimalna stabilnost nultog protoka, nezavisna od svojstva medija » Minimalna dužina ulazne i izlazne deonice
