NivuFlow Mobile 550

Contactless flow metering for long-term measuring in part filled pipes and channels

NivuFlow Mobile 550 permits contactless flow metering in a variety of different situations. Hydraulic algorithms determine the exact flow profiles for almost all shapes.The modern operating concept via web browser in connection with tablet, smartphone etc. is intuitive and enables quick commissioning. Here, a quick start assistant guides you through the most relevant parameter settings. While setting parameters, the remaining operation time is indicated in days.The optional built-in modem provides automatic data transmission via e-mail, FTP or to the NIVUS WebPortal. The energy-efficient system allows for accurate scheduling of maintenance visits and very long operation times.
