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.
NOS rod 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. Due to their mechanic construction the sensors are particularly suitable for use in part filled flumes with vertical walls.
The sensor holders are designed to install the sensors above the water level. The water level hence does not need to be lowered and moreover divers are not needed.
