- Resistant sensor material for use in various media
- Measurement in full pipes. Ideal for retrofitting or replacement.
- Measurement in clear to slightly polluted water
- One sensor type for all diameters (DN 100 to DN 6.000)
- Up to 100 m of cable length between sensor and transmitter or adapter box
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.
Typical NIS pipe 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
- Dirty water pipelines
- Industrial flow measurements, process water
- Retrofitting and Replacement of existing flow measurement system
- and many more
