Flow Sensors
NOS Screw-in sensor
Part No. NOS-V2X00for pressurised pipelines
For high accurate flow measurement using the transit time method according to IEC 60041 process water and high pressure lines.
Description
- 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.
Typical NOS screw-in sensor applications
- 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
