District heat and cold measurement

ULTRAHEAT T450

T450 – the universal thermal energy meter. Applicable in building services and district heating – precise, reliable, flexible and with a high degree of economic efficiency, the ULTRAHEAT®T450 is a compact and flexible ultrasonic meter suitable for the most demanding of application and operating conditions. Robustness, easy installation, on-site configurations, retrofitting of communication modules, sensors or power supply – are 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.

ULTRAHEAT T230 

The smart ULTRAHEAT®T230 is a next generation ultrasonic heat or cooling meter especially developed and optimized to meet all residential needs. Lightweight, robust and good economic efficiency and user-friendliness, the T230 has significantly lower pressure losses, which simplify the dimensioning of the meter and economize expensive operating current year by year. With the huge dynamic range of 1:1000 all flow rates can precisely be measured, even the smallest. The hard-coded starting value amounts only a few liters per hour and wouldn´t be affected by soiling or abrasion. The T230 works with the proven ultrasonic measurement technology of Landis+Gyr giving the highest accuracy, no maintenance and stable measurement for many years.
