NivuFlow 600 Flow Meter

Part No. NF6-0

flow measurement for full pipes

Allows high accurate flow measurement using the transit time method in full pipes. Up to 4 measurement paths.

  • Ultrasonic transit time measurement
  • Single or multi path measurement, up to 32 measurement paths with extension modules
  • Flow meter for insert or non-contact clamp-on-sensors
  • Easy installation without process disruption
  • Easy start-up due to menu guided sensor positioning
  • High accurate flow measurement in clean and slightly polluted media
  • Intuitive, modern operating concept
  • High-resolution graphic daylight display
  • Extensive diagnostic functions for reliable initial start-up and quick maintenance

General description

The NivuFlow 600 system was developed particularly for flow measurement in full pipes. To meet the highest accuracy requirements it is possible to equip the transmitters with up to 4 measurement paths, with up to 32 velocity paths. There are pipe sensors as well as contactless clamp-on sensors available for the measurement system. It is not necessary to interrupt running processes to install both sensor types. The system is suitable for the detection of flow rates in various liquid media covering a wide range of applications.

 

Typical applications

  • Hydropower
  • Leakage monitoring
  • Irrigation systems (volume distribution and billing)
  • Inlets and outlets conducting cooling water or circulation systems
  • Industry: process water, slightly polluted water and more
  • Comparative measurements
  • Pump monitoring and verification

The measurement principle

The NivuFlow 600 measurement principle utilizes the advantages of transit time. With this technolgoy ultrasonic signals between two sensors are measured. The transit time in flow direction is shorter than it is against the flow direction. The difference between both transit times is proportional to the average flow velocity along the measurement path. With the number of the measured paths the accuracy rises accordingly.
