Se vores produkter i denne kategori
Nøjagtig og pålidelig måling af hele dit dampflow.
I modsætning til andre teknologier, kan du med en TVA flowmåler måle hele flowområdet.
Ved at opfange al dampen, som bruges indenfor dit maksimale og minimale flowområde, kan du føre nøjagtig og omfattende kontrol med dit energiforbrug.
Måler hele dit dampflow område - 50:1 turndown bedste praksis damphastigheder.
Meget nøjagtig - målinger hjælper med at identificere mulige energibesparelser og nedbringer spild.
Nem integration og installation - med kontrolsystem og eksisterende rørledning.
Lang driftslevetid - gennemtestet og robust kontrolsystem betyder høj pålidelighed.
Lav ejeromkostning - hurtig installation kombineret med fremragende pålidelighed.
