flow monitoring
- Direct sensor connection to flow transmitters such as NivuFlow Mobile 750
- Small construction height
- Minimal 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 tor NivuFlow Mobile 750. 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
