NIVUS - Model NOS-V2X00 -Screw-in Flow Sensor

• Ultrasonic transit time sensor for connection to NivuFlow 600 and NivuFlow 650
• High accurate monitoring of hydropower plants
• Resistant sensor material for use in various media
• Measurement in clear to slightly polluted water
• Hydropower plant monitoring with highest measurement accuracy  
• For 8-path measurements according to IEC 60041 (ASME PTC 18
• Up to 100 m of cable length between sensor and transmitter or adapter box

NOS screw-in sensors are part of a fixed measurement system for continuous flow measurement and storage of the recorded measurement data. They can be used for clean to slightly polluted media.
NOS screw-in sensors are used for flow measurement in full pipes featuring various dimensions.

Readings are detected based on the ultrasonic transit time principle. Creating a standardised measurement network by installing up to 8 measurement paths according to IEC 60041 allows high accurate measurement results.

• Fixed measurements in full pipes in hydropower plants, pump stations and similar
• Irrigation systems
• Inlets and outlets conducting cooling water or circulation
• WWTP outlets and many more
• Industrial flow measurements, process water, pressurised pipelines
• and many more
