Flow Sensors

CS2/ CSP Correlation Wedge Sensor

Part No. CS2/CSP

Large measurement range for high flow levels

Ultrasonic sensors for flow measurement with very high accuracy in slight to heavily polluted media. For installation on channel wall or channel bottom

Description
  • Für Durchflussmessungen mit sehr hoher 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
  • Für alle Kanalquerschnitte geeignet
  • Die abgestimmte Auswahl an Sensorbauformen gewährleistet eine optimale Lösung für jede Applikation

Die CS2 Fließgeschwindigkeitssensoren sind zur kontinuierlichen Messung in leicht bis stark verschmutzen Medien in Gerinnen mit vorrangig großen Füllständen geeignet. Die Keilsensoren sind zur Befestigung auf dem Gerinneboden oder an der Gerinnewand konzipiert. Sie bilden in Kombination mit Messumformern wie z.B. NivuFlow 750 sowie einer externen Füllstandmessung ein komplettes Durchflussmesssystem.

Typische Anwendungen für den CS2 Keilsensor

  • Kläranlage: Zulauf, Ablauf, Zulauf zu den Belebungsbecken, Rücklaufschlamm, Rezirkulation, Überschussschlamm, Ablauf vom Faulbehälter und Flockungsmitteldosierung
  • Industrielle Abwassernetze
  • Große Sammelkanäle
  • Besonders für große Kanäle mit Füllständen ab 500 mm geeignet

Outside cable diameter
  • Combi sensor with pressure measurement: 9.75 mm ±0.25 mm
  • Sensors without pressure measurement: 8.4 mm ±0.25 mm
Sensor connection
  • Cable end pre-configured for connection to NivuFlow 750
  • Cable end with plug for connection to NivuFlow 750
  • Cable end with plug and pressure compensation element (sensors with pressure measurement cell only) for connection to NivuFlow Mobile 750
Sensor types
  • v-sensor with T-compensation
  • v-sensor with T-compensation and h measurement (water-ultrasound)
  • v-sensor with T-compensation and h measurement (hydrostatic)
  • v-sensor with T-compensation and 2 x h measurement (water-ultrasound + hydrostatic)
Medium-contacting materials

Polyurethane, stainless steel 1.4571, PPO GF30, PA6
