General description

The NivuFlow 650 is compliant with ISO 6416, IEC 60041 as well as ISO 748 and has been developed for accurate flow measurement in open channels, part filled and full pipes and surface water bodies. To meet the highest possible accuracy requirements it is currently possible to utilise the NivuFlow 650 using up to 4 velocity paths, with extension modules up to 32 velocity paths. 
The NivuFlow 650 operates over the full bi-directional flow range without causing obstruction or head loss where the large array of NIVUS transducer models permits flow measurement across the widest possible range of applications.

The compact transmitter design can be easily integrated into instrument cabinets using a DIN rail mounting system and is also available with a field enclosure that provides full protection under harsh environmental operating conditions. The transmitter‘s large graphic display allows quick and easy commissioning of the flow metering system.

The NivuFlow 650 provides extensive diagnostic options and allows in-depth analysis of operational function on site. The system has been developed using future-proof protocols complete with versatile choices for communication and I/O connections that open up a wide range of options for operators to integrate the instruments into SCADA or similar operating systems.

Typical NivuFlow 650 Applications

• Measurement of surface waters such as rivers, channels and similar
• Irrigation systems (volume distribution and billing)
• Drainage systems
• Hydropower plants (turbine efficiency and turbine optimisation etc.)
• Inlets and outlets conducting cooling water or circulation systems
• Penstock monitoring
• Industrial process waters
