Innovation, reliability and maximum accuracy
Together with the sensors, the NivuFlow 750 forms a stationary measuring system for continuous flow measurement and flow control for low to heavily contaminated media of various compositions. It is used in part filled and full flumes, canals and pipes of various geometries and dimensions. The measurement transducer is able to record the current flow rate at a maximum of 3 different measuring points with up to 81 flow velocity sensors.
Typical applications
- WWTPs
- Channel networks
- Discharge structures
- Industrial wastewater networks
- measurement places for billing
- intakes
- drainage lines
- return sludge lines
- recirculation lines
- and many more
The right sensor for each application
A wide selection of sensor designs is available for measuring flow velocity and flow level in flumes, pipes and canals ranging from very small to several metres in size: Flow velocity sensors with and without integrated flow level measurement as well as air-ultrasonic flow level sensors.
Highly resistant sensors in PEEK design with Hastelloy mounting plates or in titanium design and FEP-protected cables withstand even highly aggressive and corrosive environments.
Nivu Flow 750 - Universal transmitter
The intuitive one-hand operation and the bright high-resolution colour display allow quick, easy and cost-efficient commissioning on site. Additional input devices or software are not required.
The latest integrated numeric discharge models enable more accurate, more stable and more reliable determination of flow rates even under very difficult measurement conditions. The 3D flow profile is calculated in real time and is reproducibly and verifiably indicated on the transmitter display. Factors influencing the calculation results such as channel shapes, discharge behaviour and wall roughness are considered during flow calculation.
Delayed discharge behaviour and variable backwater effects are reliably recorded and taken into account in the calculation. In addition to the compact DIN rail version there is a weatherproof field unit available featuring appropriate connection space for outdoor installation
