Flow Sensors

CS2 Correlation Pipe Sensor

Part No. CS2-V1

Large measurement range for big pipes

Ultrasonic sensors for flow measurement with very high accuracy in slight to heavily polluted media. For installation in pipes up to 5000 mm diameter

Description
  • Sehr hohe Genauigkeit durch Ultraschall-Kreuzkorrelationsverfahren
  • Störsichere Verbindung über lange Distanzen durch digitale Signalübertragung
  • Kabelverlängerungen mit Standardkabeln problemlos möglich
  • Absolut nullpunktstabil und driftfrei
  • Messung in stark verschmutzen und abrasiven Medien
  • Einfache Montage ohne zusätzliche Einbauten und optimal abgestimmtes Montagezubehör
  • Montage unter Prozessbedingungen möglich
  • Besonders für Rohrquerschnitte ab DN 1000 geeignet

Die CS2 Fließgeschwindigkeitssensoren sind zur kontinuierlichen Messung in leicht bis stark verschmutzen Medien geeignet.

Die Rohrsensoren sind zur Befestigung über Stutzen von außen an Rohren konzipiert. Sie bilden in Kombination mit Messumformern wie z.B. NivuFlow 750 sowie einer externen Füllstandmessung ein komplettes Durchflussmesssystem.

 

Typische Anwendungen für den CS2 Rohrsensor

  • Kanalnetze: Verrechnungsmesstellen, Durchflussmessung in großen Rohrquerschnitten
  • Kläranlage: Zulauf, Ablauf, Zulauf zu den Belebungsbecken, Rücklaufschlamm, Rezirkulation, Überschussschlamm, Ablauf vom Faulbehälter und Flockungsmitteldosierung
  • Industrielle Abwassernetze
  • u.v.m.
