  • Exact flow measurement

    NIVUS flow measurement systems stand for innovation and highest accuracy. The OCM Pro CF, proven a thousand times, is a permanent measurement system for continuous flow measurement , flow control and storage of recorded flow data within the range of slight to heavily polluted media of various consistencies. The system can be used as initial equipment or retrofitting in part filled and full flumes, channels and pipes featuring various shapes and dimensions. OCM Pro CF provides fast processors for signal processing, Modbus TCP as well as online connection via Internet.

    For flow velocity measurement starting at flow levels as low as 3 cm up to several meters there is a wide selection of sensors available.

    On site from anywhere

    The OCM Pro CF features innovative communication options for remote maintenance, remote diagnostics and data transmission. Thanks to these options modern measurement systems can be networked all over the world. The unit provides a dedicated webpage via TCP/IP using the integrated web server. In addition to the connection to the worldwide Internet, the unit can be used within internal networks as well.

    NivuFlow 750 Flow Meter

    High accurate with intuitive operation

    For ultrasonic flow measurement of slight to heavily polluted media in part filled and full pipes and channels. Best possible results even under difficult conditions.

    Benefits
  • Very high accuracy flow meter
  • Up to 3 measurement spots as well as up to 9 flow sensors (Version M9)
  • Real-time indication of real flow velocity profiles
  • Suitable even for very demanding applications
  • Intuitive, modern operating concept for quick and easy commissioning
  • Large colour graphic display
  • Integrated numeric flow models
  • Ultrasonic flow measurement in all channels, part filled and full pipes as well as flumes
  • No calibration required
  • Comprehensive diagnostic functions for reliable commissioning and quick maintenance
  • Spatial allocation of measured single velocities
  • Compact DIN rail flow meter for narrow switching cabinets
  • Field enclosure with large terminal housing for comfortable installation on site
  • Quick wiring thanks to front-side access
  • Universal standardised interfaces for easy connection


  • Flow metering at the highest technical level

    The NivuFlow 750 flow meter is the successor to the well-known OCM Pro CF. Compact dimensions of the flowmeter allow DIN-rail installation and installation in switching cabinets even under confined space conditions and in narrow housings.

    Combined front-side cage spring terminal clamps ensure quick and easy wiring as well as quick and easy transmitter exchange without tools.

    The modern, intuitive one-hand operation using the rotary pushbutton in context with the high-resolution, easy-to-read graphic colour daylight display allows very quick and easy, cost-efficient commissioning on site. No extra input devices or software components are required.

    The latest integrated discharge allow even more accurate and more stable investigation of flow rates at high operational reliability even under very difficult measurement conditions. Based on the ultrasonic correlation method, individual velocities are detected in different levels of the flow section. A real 3D flow profile is calculated in real time and is indicated in a reproducible and verifiable manner on the flow meter diaplay. Influencing factors such as flume shape, discharge behaviour and wall roughness are taken into account and are considered while computing the flow.

    The NivuFlow 750 offers control function as well. i.e. for flow control in storm water basins or storm water retention basins as well as in sewers with storage capacity and overflow.

    The NivuFlow 750 flow meter features quickest possible signal processing, Modbus TCP/RTU as well as online connection via Internet.

    For flow velocity measurement starting at flow levels as low as 3 cm through several meters in flumes and channels with various shapes and dimensions, there is a wide variety of sensors tailored to your application available.

    On site from anywhere

    NivuFlow750 flow meter provides options for remote maintenance, remote diagnostics and for flexible integration into process control systems and telecontrol networks. Thanks to the integrated web server NivuFlow 750 there is an own web site available via TCP/IP. This allows to connect the unit to the worldwide Internet as well as to internal networks.
