Thermodynamic Pump Monitoring System
Our industry leading FREEFLOW portable thermodynamic pump testing system is an easy to use, self-contained thermodynamic instrument. It is one in our range of pump testing systems designed to measure pump performance characteristics on industrial pumps.
Why use a thermodynamic pump testing system?
Using our thermodynamic method remains the most accurate and powerful means of testing a pump. The portable system makes this easy to do in-situ, without compromise to safety or disruption to operations.
By simply measuring temperature and pressure across the pump, our precision technology calculates the efficiency and head of the pump (to an impressive accuracy of up to 0.5%). Then, by measuring the power consumed by the motor, we can calculate flow rate.
How the FREEFLOW portable works
Where existing pipework fittings are installed, an experienced technician can complete a typical pump test in less than two hours. A range of test points are taken at different flow rates, across the operating range of the pump. This data is used to plot performance curves of the pump under test.
Know what’s happening in your stations*
When we undertake Pump Monitoring and Optimisation, we manage, visualise and report on your pump assets and operational efficiency, providing real-time data and visualisations that will enable you to see what’s happening in your stations.
Each project focuses on the whole-life management of your assets and drives efficiency gains through dynamic optimisation using our easy-to-install pump monitoring kit.
*Essential for pumps 250kW or larger.

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.

- Integrates with SCADA, standalone or web-access (security assured)
- Delivers the following real-time data, which are the building blocks of optimisation: pump efficiency (%), motor power (kW), flow rate (l/s) and pump head (m).
- The following measurements are taken: hydraulic measurement (differential temperature, suction pressure, discharge pressure), electrical power measurement (kW), asset performance information and motor efficiency measurement (%).
- Captures, processes and provide data to managers and operators via our interface software. Every minute of the day and night, enhanced information is made available from FREEFLOW to improve station efficiency and reduce operating costs.
HydraNET
HydraNET – Real-Time Decision Support Software WorkStation to Unlock Hidden Efficiency Across Your Entire Network
Riventa HydraNET transforms how you manage your pumps by using real-time data and intelligent algorithms to automatically schedule operations for maximum efficiency. Whether you’re aiming to cut energy costs, extend equipment lifespan, or boost system reliability, HydraNET delivers the insight and control you need to run smarter, leaner, and more sustainably.
Key features:

- Optimises pump scheduling by automatically selecting the most efficient pump or combination based on real-time performance data
- . Analyse system demand and adapt pump operation accordingly
- Historical Data
- Reduces energy consumption and electricity costs by identifying underperforming or energy-wasting pumps
- Extends pump lifespan by avoiding inefficient operations and overloading
- Continuously visualise pump efficiency, energy usage, and savings in real time through intuitive dashboards
- Supports sustainability goals by improving operational efficiency
- Delivers fast ROI through cost savings and improved asset utilisation

Network Optimisation
The purpose of HydraNET Network Optimisation is simple. It ensures your entire pumping system works in perfect harmony. By analysing real-time performance across all assets, HydraNET identifies the most energy-efficient combinations, minimises wastage, and adjusts operations dynamically to meet changing demand. It’s not just about saving power; it’s about gaining full control over your network, reducing operating costs, and achieving performance you didn’t know was possible.
Network Optimisation utilises data inputs such as tariffs, storage tank levels, demand prediction, and hydraulic conditions to generate an optimal schedule for the next 24-48 hours, achieving a minimal cost given any network constraints.
Predict demands, have a hydraulic model, and use some math to calculate the least cost solution over 48 hours; simulated every 15 minutes
Can provide an offline schedule (decision support, open loop) or an online system directly controlling infrastructure (real-time, closed loop)
