FREEFLOW fixed thermodynamic pump monitoring system

The FREEFLOW fixed box, designed for thermodynamic pump monitoring

Our industry-leading FREEFLOW fixed thermodynamic pump monitoring system is an easy to use, self-contained piece of kit. It is used to monitor pumps at medium to large stations, and is one in our range of monitoring systems designed to optimise performance in relation to industrial pump systems.

The FREEFLOW fixed system is one of our pump monitoring systems. We can specify, deliver, install and commission a pump station monitoring solution directly to your pumping system. Contact us for more

Why use a thermodynamic pump monitoring system?

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

Often hidden characteristics are discovered that can lead to major improvements in overall operating efficiency and pump lifecycle costs. Results can provide valuable pump data that will make real-time optimisation a reality, and deliver a platform for planning capital expenditure and minimising whole-life costs. Pump monitoring is also able to reduce energy consumption, carbon emissions, hydraulic failure and premature wear.

The extremely precise measurements delivered by our FREEFLOW fixed system will help you to:

Obtain accurate, quality data about your assets

Analyse and visualise performance

Increase station efficiency and performance

Maximise energy saving opportunities

How the FREEFLOW fixed works

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

Our FREEFLOW fixed pump monitoring 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.

Real-time data

Our FREEFLOW fixed system delivers the following 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 (AT, Ps, Pd), electrical power measurement (kW), asset performance information and motor efficiency measurement (%).

What’s included:

System highlights

  • Works with any high energy pump (with a head of 40m or more)
  • Enables motor efficiency to be measured using our patented technology
  • Measures individual pump efficiency and flow rate
  • Supports planned maintenance programmes by tracking reduction in pump efficiency
  • Trends data to predict the most cost-effective time for pump replacement, refurbishment, coating or other remedial maintenance
  • Provides pump head, flow, efficiency, power and motor efficiency
  • Integrates with SCADA, standalone or web-access (security assured)

System components

  • One FREEFLOW pump monitor
  • One set of precision temperature transducers
  • One 10-bar suction pressure transducer
  • One 20-bar delivery pressure transducer
  • One power measurement system (LV/HV)
  • One touch screen local operator panel
  • Two insertion glands per pump

Operator interface software

  • Alongside system components, our FREEFLOW fixed pump monitoring system 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
