Radar Flow Meter
Contactless flow measurement for opeggn channels and part filled pipes
Contactless Radar Flow Metering
The contactless low-maintenance radar sensor provides reliable operation even at very high discharge velocities with low flow levels. Dynamic hydraulic models for various channel shapes based on varying filling levels enable accurate detection of the real flow rate.
Introducing the NivuFlow 7550 we provide a transmitter for Hybrid flow measurement using radar and ultrasonic technology.
Easy Installation and Handling
Due to DIN rail mounting options the compact transmitter saves space and can be installed easily in control cabinets. Moreover the NivuFlow 550 is available with a special protected field enclosure for use under harsh ambient conditions. The large graphic display permits quick and easy commissioning of the flow meter system.
Due to the modular construction of our radar flow meter system we can provide the appropriate solution for each application
NivuFlow 550 provides extended diagnostic options and facilitates in-depth analysis of running processes on site. The transmitter software is in line with current requirements. Future-proof protocols and versatile communication and integration options open many ways for operators to integrate the devices into higher systems such as SCADA or process control systems.

TFXL ultrasonic transit time flow meter measures most clean liquids and liquids with small amounts of suspended solids or aeration, such as surface water or sewage.
Allows high accurate flow measurements using the transit time method according to IEC 60041 for part filled and full pipes, open channels and water bodies. Up to 8 measurement paths
The Dynasonics DFX Ultrasonic Doppler flow meter features a clamp-on design that streamlines installation and eliminates the worries of fluid compatibility and pressure head loss.
