The Landis+Gyr T550 (UH50) is an advanced ultrasonic heat and cooling energy meter designed for accurate measurement of thermal energy in heating and cooling systems. Using ultrasonic flow measurement technology, it measures water flow and the temperature difference between flow and return lines to calculate energy consumption. The meter is suitable for district heating, district cooling, commercial buildings, HVAC systems and multi-family residential applications. It is available in heat meter, cooling meter, combined heat/cooling meter and flow meter configurations.
The Landis+Gyr T550 UH50 offers reliable ultrasonic measurement with no moving mechanical parts, a wide measuring range, integrated data logging, monthly consumption records and self-diagnostic functionality. It supports optical communication as standard, with optional M-Bus, pulse, analog, radio and other communication modules. The meter can operate using battery or external power supply and supports flexible installation orientations in flow or return lines. It is suitable for HVAC energy monitoring, district energy networks, commercial buildings, shopping malls, IT parks, hotels and industrial facilities.
