Frequently Asked Questions

Was bedeutet ATEX-Zertifizierung beim FlowGuard® FT420 EX?

Das FlowGuard® FT420 EX ist nach ATEX-Richtlinien für explosionsgefährdete Bereiche zertifiziert: I M1 Ex ia I Ma (Bergbau), II 1G Ex ia IIC T6 Ga (Gasatmosphären Zone 0-1) und II 2D Ex ia IIIC T85°C Db (Staubatmosphären Zone 20-22). Dies gewährleistet sicheren Betrieb in chemischen Anlagen, Raffinerien und Minen.

Welche Vorteile bieten 800 Messungen pro Sekunde?

Die hohe Messfrequenz von 800 Messungen/Sekunde ermöglicht präziseste Dosierungsprozesse in der Pharmaindustrie, Chemie und Lebensmittelproduktion. Selbst schnelle Durchflussänderungen werden exakt erfasst, was bei kritischen Dosiervorgängen entscheidend ist.

Für welche Medien ist der FlowGuard® FT420 EX geeignet?

Alle leitfähigen Flüssigkeiten ab 20 µS/cm können gemessen werden: Wasser, Säuren, Laugen, Schlämme, Pasten. Verschiedene Auskleidungen (PTFE, Gummi) und Elektrodenmaterialien (Hastelloy, Titan, Tantal) ermöglichen den Einsatz bei aggressivsten Medien.

Warum ist der Durchflussmesser wartungsfrei?

Die magnetisch-induktive Messtechnik kommt ohne bewegliche Teile aus. Das Faraday'sche Induktionsgesetz ermöglicht berührungslose Messung - kein Verschleiß, keine Verstopfung, kein Druckverlust. Einmal installiert, arbeitet das Gerät jahrelang zuverlässig.

Welche Installationsvorteile bietet die Kompaktbauweise?

Die Integration von Sensor und Elektronik in einem robusten Edelstahlgehäuse spart Platz, reduziert Verkabelung und erhöht die Störsicherheit. Die verschiedenen Prozessanschlüsse (Flansch, Sandwich, Gewinde, Clamp) ermöglichen flexible Integration in bestehende Rohrleitungen.
