Retaining the proven to create something new.


Versatile installation options
The extremely compact design of the T330, as well as the rotatable and detachable calculator simplify the installation of the meter and facilitate reading. Even where there is a lack of space, such as for example in narrow meter cabinets or poorly accessible places, the T330 can be used effortlessly.


Platform strategy
For more than five decades the Landis+Gyr ultrasonic meters have been successful in tough district and residential heating applications.
Recognised and well-proven meter components have been improved and combined into a new concept. The precision of the measuring unit and the consistent operating concept of the calculator ensure familiar handling of the T330, such as installation, operation and readout.


Excellent measuring stability
The T330 has a full-metal measuring unit without moving parts in the measuring channel and is equipped with the special internal profile DuraSurface™. This makes it insensitive to soiling and ensures failure-free operation with constant measuring accuracy over many years.


New advanced features
The advanced software features ensure easier handling of the measurement data and help the thermal energy meter to adapt intelligently to changing situations in order to deliver precise measurement results.

  • Adaptive measurement
  • Temperature compensation
  • Manual Parameterisation
  • Statistical values
  • Monthly values, due dates
