Level Sensors

P-Series Sensors

Part No. NMS

Ultrasonic sensors for level measurement

P-Series sensors are suitable for continuous level measurement in the water and wastewater sector. For connection to NivuMaster-Series evaluation units. Suitable for harsh ambient conditions.

  • 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
