  • Intuitive, Time-Saving Operation

    Web server

    A common requirement in water and wastewater applications is that operation should be as simple as possible. Similarly non-specialist technicians should be able to commission and replace devices.

    Our solution: Proline’s web server gives quick access to device, diagnostics and process information. A standardized, user-intuitive “human-machine interface” with guided parameterization reduces complexity of operation.

  • Lifetime Guarantee

    Reliable long-term operation

    For outdoor installations, devices must be able to withstand heat, dust or extreme climatic fluctuation. For continuous underwater or underground use, they must be corrosion-resistant and watertight. Where water quality is involved, high accuracy and maximum reliability are absolutely essential.

    Our solution: Certified Proline devices are designed to be the best-fit for your application. In addition, Heartbeat Technology enables continuous diagnostics and comprehensive device verification, extends inline calibration intervals and fulfills ISO 9001 traceability requirements.
