    Flow Sensors - Overview

    Used in water management, leak detection, and irrigation. These ultrasonic sensors measure the flow velocity of water and calculate the volume and flow information. The average water flow is measured by emitting and receiving ultrasonic signals. The more ultrasonic paths one uses, the higher the system accuracy.

    Type A for filled or partially filled pipes with a 0.75–35 m diameter.

    Type B for open channels & filled or partially filled pipes with a 0.75–35m diameter.

    Type C for filled or partially filled pipes with a 0.20 – 35 m diameter.

    Type K sensors for applications in open channels

    Type G externally mounted clamp-on sensors

    Flow Sensors - Features

    • Wide range of open channel widths of up to 130 meters
    • Wide range of pipe diameters of up to 52 meters
    • Up to 20 paths per measurement section
    • High accuracy of up to 0.5% in the field & 0.2% under ideal conditions
    • High flexibility for configurations such as crossed/non-crossed setups
    • Easy to retrofit into existing, even third-party installations
    • Drift-free and long-term stability
    • No moving parts

    Ultrasonic Flow Transmitter | RISONIC Modular

    Ultrasonic Flow Transmitter - Overview

    The RISONIC modular system consists of three components:

    • The Controller: Integrated data logger, limited value monitoring, volume counter, Individually galvanically isolated I/O's, SMS alarm via external GSM / GPRS modem
    • Up to five RISONIC Ultrasonic Transit Time Modules: prepare and process the sensor signals, which then get sent to the controller
    • Various ultrasonic sensors that are mounted internally or externally, or non-invasively to the outside of the pipe

    This modular measurement system for hydroengineering applications was developed for ultrasonic flow measurements in open channels and filled and partially filled pipes. The modular design makes it suitable for a broad spectrum of applications, whether for turbine and pump efficiency measurements, penstock leak detection, or flow measurements in water supplies or irrigation systems. The system is user-friendly and intuitive, so it requires minimal training. It can be remotely serviced with a variety of diagnostic functions to pinpoint malfunctions quickly, reducing downtimes. Suitable for use in hydropower plants, water supplies, irrigation systems, and water cooling circuits.

    Ultrasonic Flow Transmitter - Features

    • Excellent long-term stability, no need for recalibration
    • Easy commissioning and signal analysis
    • Wide range of ultrasonic transducers for pipes and channels
    • High measuring accuracy of up to 0.5% of measured value displayed
    • Up to 4 measurement sections per Controller (incl. multi-pipe, multi-channel)
    • Flow measurement in both directions (pump storage power plant)
    • 1 ... 5 ultrasonic modules for a maximum of 20 measurement paths (5 x 4)
    • Modular concept of ultrasonic modules reduces cost for lower path sections
    • Controller with built-in web server for easy configuration
    • IEC 60870-5-104 and Modbus RTU/TCP communication
