Level Sensors

OCL Air-Ultrasonic Sensor

Part No. OCL

for level measurement in combination with flow measurents

Intelligent air-ultrasonic sensor for connection to flow transmitters such as NivuFlow 750, OCM Pro and PCM for non-contact level measurement in part filled flow measurement places.

  • Direct sensor connection to flow transmitters such as NivuFlow 750, OCM Pro and PCM
  • Small construction height
  • Low dead zone
  • Digital echo processing and linearisationNarrow beam angle
  • Optimised construction for small pipes
  • Easy installation using pipe mounting system or direct fasting using bolts
  • View echo profiles on the transmitter
  • Integrated temperature compensation
  • ATEX approval for Ex-Zone 1

The compact air-ultrasonic sensor Type OCL has been developed for direct connection to portable and permanent flow transmitters such as NivuFlow 750, OCM Pro and PCM.
Thanks to the slim construction it is ideally suitable for use in the crown of small and large pipes, on channel ceilings or other constructions.
The low dead zone allows to measure variable levels in flow applications almost up to full filling. The integrated temperature measurement ensures very high accuracies over the entire very wide measurement range.
The ATEX approval in Ex Zone 1 is a standard feature.
