NIS pipe 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.
NIS pipe sensors are used for flow measurement in full pipes featuring various dimensions.
Readings are detected based on the ultrasonic transit time principle which allows high accurate measurement results.
Thanks to perfectly matched mounting material ranging from ball valves to tapping saddles the system is ideal for retrofitting or for replacement of existing flow measurement systems.
