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
