Very low in maintenance through non-contact measurement
Extremely versatile thanks to measurement ranges from 0.07 m to 40 m
Protection IP 68
ATEX approval for Ex-Zone 0 and 1
Alarm output in case of flooding possible
Resistant to moisture, aggressive environments and heavy temperature fluctuations

The ultrasonic sensors with integrated temperature compensation for connection to NivuMaster- Series evaluation units provide a wide variety of measuring options for liquids.

The sensors provide accurate and reliable readings even in narrow tanks, no matter what measurement range or application. False echoes reflected from built-in obstructive constructions are negligible since they will be avoided automatically.
The sensors are available with 1"-thread or as flange version according to DIN and thus can be installed without any problems.

Typical applications for P-Series sensors

Level measurements in the water and wastewater sector
Flow measurements in open flumes and weirs
Volume measurements in tanks
Comparative measurements on screens
Pump control in pump stations
