NIVUS - Model NOS-VX0B -Hemispheric and Ballhead Flow Sensor

• 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.

• 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
