Introduction
The ULTRAHEAT
®
XS heat meter is a measuring instrument for
physically correct recording of heat consumption. It is required to
be certified by law in Germany and many other countries. The
device consists of a volume measuring unit, two permanently
connected temperature sensors, and an electronic unit that calcu-
lates the heat consumption from the volume flow and temperature
difference.
The volume measuring unit is a non-wearing ultrasonic measuring
device without mechanically moving parts. The long-life battery is
designed for the calibration validity period. ULTRAHEAT

cannot be opened without breaking the calibration seal.
The heat meter must only be operated under the conditions stated
in the device sheet and on the rating plate.
