NIVUS - Model P-Series -NMS -Ultrasonic Sensors for Level Measurement

• 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.

• 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
