1.<\/strong>Inleiding<\/strong><\/h3>\n

De ultrasone Doppler-debietmeter is gebaseerd op het Doppler-effect. De sonde zendt een bundel ultrasone golven schuin omhoog uit. De ultrasone golven verspreiden zich in de vloeistof. De vloeistof kan onzuiverheden bevatten, zoals luchtbellen of deeltjes (men kan ervan uitgaan dat de onzuiverheden in de vloeistof dezelfde snelheid hebben als de waterstroom). Wanneer de ultrasone golven in contact komen met de onzuiverheden in de vloeistof, veroorzaken de gereflecteerde ultrasone golven een Doppler-frequentieverschuiving \u0394f. De Doppler-frequentieverschuiving \u0394f is evenredig met de stroomsnelheid. De stroomsnelheid van de vloeistof kan worden gemeten door de Doppler-frequentieverschuiving \u0394f te meten.<\/p>\n

Stroomkabel:
\nRode draad aangesloten op de pluspool van de voeding (12V+ of 24V+);
\nGroene draad aangesloten op de minpool van de voeding (12 V of 24 V);<\/p>\n

Signaalkabel:
\nWitte draad aangesloten op RS485A (T\/R+);
\nGele draad aangesloten op RS485B (T\/R-);<\/p>\n

Doorzichtig luchtkanaal:
\n\u203bEr moet een onbelemmerde verbinding met de buitenlucht worden gewaarborgd; let bij de installatie op de bescherming ervan<\/b><\/strong>, met name bij het doorvoeren door de draadbuis, is het noodzakelijk om deze v\u00f3\u00f3r het draadtrekken met tape af te plakken om het binnendringen van water te voorkomen. Als er toch water binnendringt, kan dit leiden tot fouten in de waterdiepte en andere verschijnselen.<\/p>\n

Het doorzichtige luchtkanaal mag niet worden gevouwen en de buighoek mag bij het doorvoeren van de buis niet kleiner zijn dan 90\u00b0.<\/p>\n
