Flow Sensors

KDA Doppler Pipe Sensor

Part No. KDA-R/KDS-R

Flow velocity sensor for installation in pipes

Ultrasonic sensors for flow measurement in slight to heavily polluted media. Designed for fastening in pipes using a nozzle

Description
  • Neueste intelligente Doppler-Technik der vierten Generation
  • Kostengünstig in der Anschaffung
  • Für alle Rohrquerschnitte geeignet
  • Einfache Montage ohne zusätzliche Einbauten
  • Kabelverlängerungen problemlos möglich
  • Messung in stark verschmutzen und abrasiven Medien

Die KDA Fließgeschwindigkeitssensoren sind zur kontinuierlichen Messung in leicht bis stark verschmutzen Medien geeignet. Die Rohrsensoren sind zur Befestigung über Stutzen von außen an Rohren konzipiert. Die Sensoren ergeben in Kombination mit den Messumformern OCM F / OCM FR ein komplettes Durchflussmesssystem.

Typische Anwendungen für den KDA Rohrsenohr

  • Kläranlage: Zulauf, Ablauf, Zulauf zu den Belebungsbecken, Rücklaufschlamm, Rezirkulation, Überschussschlamm, Ablauf vom Faulbehälter und Flockungsmitteldosierung
  • Stationäre Messungen an Regenbehandlungsanlagen wie RÜB, RRB, RKB
  • Direkteinleiterkontrolle, Fremdwasser- bzw. Leckageermittlung
  • Industrielle Abwassernetze
  • u.v.m.
