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.
|Measurement principle||Ultrasonic transit time and profile measurement with digital pattern detection|
|Measurement range||-15 m/s to +15 m/s|
|Flow velocity (vaverage) within path ± 0.1 % of measurement value |
Flow rate (Q) ±0.5 - 5 %, depending on number of measurement paths and hydraulic conditions
Offset velocity < ±5 mm/s
|Measurement frequency||0.9 to 1.2 MHz|
|Operating temperature||-20 °C to +50 °C|
|Cable lengths||Up to 100 m between sensor and transmitter or adapter box|
|Stainless steel 1.4404, carbon|
