Produkt beskrivelse

Hvordan det virker

Den ultrasoniske flowmeter/varmemåler med dobbelt kanalen måler den faktiske strømningshastighed på hvert punkt i rørledningen gennem to grupper af sensorer, simulerer strømningshastighedsfordelingen i rørledningen under den faktiske drift og løser nøjagtigheden af at konvertere lineær hastighed V til overfladehastighed Ѷ For at forbedre instrumentets samlede måleøjagtighed.

Den dobbeltkanals ultralydsstrømmeter/varmemåler transmitterer og modtager ultralydsbølger til hinanden gennem øvre og nedstrøms sensorer. Når den ultralydstråle forplantes i væsken, vil strømmen af væsken foretage en lille ændring i forplantningstiden, og ændringen i forplantningstiden er proportional med væskens strømningshastighed, som vist på figuren.
