General description
The NivuFlow 650 is compliant with both ISO 6416 & IEC 60041 and has been developed for accurate flow measurement in open channels, part full 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 up to 32 velocity paths available by beginning of 2017. 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 makes flow measurement possible across the widest possible range of applications
The compact transmitter design is 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
Fixed measurement of surface waters such as rivers, channels and similar
Irrigation systems (volume distribution and billing)
Hydropower plants (turbine efficiency and turbine optimisation etc.)
Inlets and outlets conducting cooling water or circulation systems
Industrial process waters and many more
