DCO Systems introduce new Easy STM V4. Get more out of your monitoring.
The latest evolution of UK-based DCO Systems’ Easy Steam Trap Monitor series, featuring more flexible installation, new mounting options, and enhanced sensing capabilities. The Easy STM V4 uses upgraded energy-harvesting technology for even more data from your steam system.

Enhanced energy harvesting
Our advanced energy-harvesting technology allows the Easy STM V4 to run on pipework as cool as 50°C. Monitoring cool traps more frequently builds better insight into whole system performance. DCO’s monitoring solution is purpose-built to cover the broad range of temperature requirements across large steam systems. Energy-harvesting devices output more data, more often, for longer; now across a broader range of conditions.
Improved loss calculations
Enhanced sensing provides more accurate loss estimations for different trap types, sizes and failure modes. Combined with our updated DiscoverRA dashboard analysis software, the Easy STM V4 measures the real cost of steam loss to your business.
Enhanced leak detection capabilities
Identify faulty equipment faster with ultrasound sensing as a standard feature. With increased accuracy through triangulation of measurements from multiple sensor readings.

Installation
Re-designed mounting makes the Easy STM V4 easier to install than ever before. Better clearance around flange fittings and a new option to install through rigid and metal-covered pipework insulation. With easier installation on steam and condensate pipework, your engineers save even more time. Virtual installation training is also available for your team through DCO.
Smartphone access
Access the Easy STM V4 from a smartphone for easier configuration and setup. Live data monitoring and extended data download all on demand on your smart device.
Hazardous Area certification
Intrinsically safe device certification for use in IEC/ATEX Zones 1 and 2 (expected Q1 2027).
