• FREEFLOWi4.0 flexible, thermodynamic pump monitoring system

    Our industry-leading FREEFLOWi4.0 thermodynamic pump monitoring system is easy to use, self-contained and wireless. It offers immense flexibility, highly suited to monitor pumps, blowers, fans and turbines at medium to large stations.

    The system can be temporarily or permanently installed on-site, directly assessing actual operational performance, continuously gathering data and driving ongoing optimisation work.

    Why use a thermodynamic pump monitoring system?

    Pump system characteristics typically change with demand and station operation, particularly within larger pumping stations where absolute precision is necessary. Changes can be observed and controlled using a thermodynamic pump monitoring system over a set period.

    Often hidden characteristics are discovered that can lead to major improvements in overall operating efficiency and asset lifecycle costs.

    Make real-time pump optimisation a reality

    Results can provide valuable data for real-time optimisation, and for planning capital expenditure and minimising whole-life costs. Monitoring can also reduce energy consumption, carbon emissions, hydraulic failure and premature wear.

    How the FREEFLOWi4.0 works

    Because a pump is usually part of a dynamic system, its contribution will vary with demand and system characteristics.

    Our FREEFLOWi4.0 system can monitor hydraulic performance and pump efficiency. In conjunction with our operator interface software, the real-time effectiveness of each pump can be evaluated, and accurate data generated to make optimisation happen.
