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
