Titan Plus BTU — Combined Energy & Thermal Metering
One Meter. Electrical + Thermal. Complete Efficiency.
The first DIN rail meter combining utility-grade electrical energy metering with EN 1434 thermal energy measurement in a single device.

Why Titan Plus BTU
Three reasons facility managers, ESCOs, and chiller plant engineers specify Titan Plus BTU for combined electrical and thermal metering.
Globally Unique
No product on the market combines kWh + BTU in one DIN rail device. Separate meters mean two vendors, two installations, two data streams.
Actionable Efficiency
See the direct relationship between electricity consumption and chiller/boiler efficiency. COP trend curves reveal degradation in real time, not in a monthly report.
Real-Time COP
Coefficient of Performance calculated on-device every measurement cycle. Thermal kWh ÷ electrical kWh — live, logged, and trended.
The Problem
District cooling operators, chiller plant managers, boiler room engineers, and HVAC teams currently need two separate meters to understand system efficiency — an electrical meter for compressor or boiler power, and a thermal meter for cooling or heating output. Two vendors, two installations, two data streams, and a manual COP calculation in a spreadsheet.
Most facilities skip the thermal meter entirely and fly blind on efficiency. When a chiller degrades or a boiler loses efficiency, nobody notices until the energy bill arrives.
Titan Plus BTU eliminates this by measuring electrical and thermal energy in one device — and calculating efficiency automatically.
How It Works
Three measurement channels, one efficiency number — calculated on-device every cycle.
Electrical Side
Class 0.5S
Same Class 0.5S metering engine as Titan Base — voltage, current, power, energy, harmonics, power factor.
Thermal Side
Dual PT1000 RTD + Flow
Dual PT1000 RTD inputs measure supply and return water temperatures. Flow data comes from an external flow meter via Modbus RS485. Thermal energy calculated using IAPWS-IF97 water property tables — accounting for temperature-dependent density and specific heat capacity.
Combined
Real-Time COP
COP = thermal energy output ÷ electrical energy input. Calculated on-device every measurement cycle and logged as a trend.
COP = kWhthermal ÷ kWhelectrical
Applications
Wherever electrical input drives thermal output, Titan Plus BTU measures both — and proves the efficiency.
Chiller Plant Efficiency
Real-time COP monitoring. Identify degrading compressors, fouled condensers, and low refrigerant charge from the combined electrical + thermal data.
Boiler Efficiency
Track thermal output vs. electrical input for boilers and heating systems. Spot efficiency losses from scaling, fouling, or burner degradation before they compound.
District Cooling / Heating
Per-tenant thermal billing with combined electrical monitoring. One device per connection point instead of two.
Data Centre Cooling
PUE and cooling efficiency tracking. Combined energy reporting for regulatory compliance and operational optimisation.

Energy Intelligence Platform
Titan Plus BTU is a complete efficiency solution — the meter and the Energy Intelligence Platform work together to deliver what no other product can. The meter calculates COP on-device every measurement cycle. The platform turns that into actionable intelligence — COP trend curves that reveal compressor or boiler degradation over weeks, electrical vs. thermal correlation analysis, efficiency benchmarking across multiple chillers or boilers, and automated alerts when COP drops below your configured threshold. Combined electrical + thermal dashboards give facility managers and ESCOs a single view of system efficiency that previously required two separate meters, two vendors, and a spreadsheet.
