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
