Intelligent measurement technology for exceptional reliability

The ULTRAHEAT®T450 is a compact and at the same time flexible ultrasonic meter which is suitable for many, especially demanding applications. Robustness, easy installation, on-site configurations, retrofitting of communication modules, sensors or power supply – these are just a few of the features that distinguish the T450. The new electronic design enables power supply via M-Bus and thereby an almost unlimited service life. The unique calibration logbook makes it possible to change the installation location, sensor type and energy unit at any time.

T450 characteristics - intelligent

Utilization of improvement potentials

The T450 provides data for billing as well as data on the current status, efficiency and usage of the heating system. This enables it to analyse consumption and draw conclusions about potential improvements and problems in the system. Customers can also use the values, e.g. minima, maxima or average values, to better assess whether their individual consumption is high or low.


Prepared for all adversities

The meter can also be used if the conditions are demanding: DuraSurface™, all-metal measuring sections and stainless steel transducers enable accurate, trouble-free operation even under adverse conditions. Soiling, abrasive particles, pressure peaks, high temperatures, line misalignment and vibrations don´t affect the exact measurement of the T450. However, environmental influences such as mechanical and electromagnetic influences do not put the T450 out of step.



The economical alternative

Intelligent power supply, economical electronics in combination with robust measurement technology and revisionable construction allow the T450 to be used for a very long time without malfunctions or maintenance and, if necessary, to be repaired. Should the meter no longer meet the state of the art standards, a firmware update on-site offers the possibility of meeting future requirements.



Be able to react to all circumstances at any time

The T450 is versatile: With exchangeable temperature sensors, exchangeable power supply and one slot for communication modules, the T450 can be adapted to the system requirements at any time. Furthermore, the T450 offers exceptional flexibility especially due to its calibration logbook. The installation location, energy unit and sensor type can be changed at any time – even during operation. Also multiple firmware updates are possible.



Simple operation and handling

The T450 focuses on practical use and ease of operation: Two push-buttons simplify the handling of the device and are easy to use, even with the lid open. Large installation spaces allow easy connection of communication cables and sensors. Electronic and communication modules are protected by a frame to prevent damage. M-Bus modules have four terminals instead of two. This allows daisy chaining, whereby junction boxes can be omitted.
