OCL Air-Ultrasonic Sensor

• Direct sensor connection to flow transmitters such as NivuFlow 750, NivuFlow 7550, NP8 and other flow meters in the NF series
• 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 the permanent NF flow transmitters series NF7 and NF 7550..

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.
