Flow Sensors
NOS Hemispheric and Ballhead Sensor
Part No. NOS-VX0BFor measurement places with various geometries
For connection to NivuFlow 650 transmitters. High accurate flow measurement based on the transit time method for open channels and waters, mainly process water channels and natural water bodies.
Description
- Ultrasonic transit time sensor for connection to NivuFlow 650
- Hydrometry with highest measurement accuracy
- Measurement in clear to slightly polluted water
- For 8-path measurements according to IEC 60041 (ASME PTC 18)
- Measurement in open channels and surface water bodies
- Resistant sensor material for use in various media
- Up to 100 m of cable length between sensor and transmitter or adapter box
NOS hemispheric and ballhead 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 in part filled and full flumes as well as channels featuring various geometries and dimensions.
Typical NOS hemispheric and ballhead sensor applications
- Fixed measurement of surface water bodies such as rivers, channels and similar
- Irrigation systems
- Inlets and outlets conducting cooling water or circulation systems
- WWTP outlets
- Investigation of infiltration/extraneous water or leakage
- Industrial flow measurements
- and many more
