Building Technologies Electronic Heat Meter CE1N5331en
HVAC Products 03.11.2005
The heat meter has a scrolling display with the following values and variables:
• Cumulative heat consumption since starting up the heat meter
• Segment test
• Due date
• Cumulative water consumption up to last due date
With the aid of the Siemeca
TM
parameterization tools the following display options can
be activated:
• Due date (only if due date and cut off date are different)
• Control number
• Current flow
• temperature Difference
• Error display (see also following section)
The heat meter is self-monitoring and can display errors that have been detected. The
cumulative values remain saved until the error occurs for the first time.
Version
The heat meter comprises the flow meter, the calculator and both temperature sensors.
The flow meter is screw connected to the pipe; it is made of brass and contains the
metering chamber with the single-jet impeller sensor. The inlet connection has a filter to
trap large dirt particles.
The heat meter is a compact version.
The calculator contains the electronics and the 8-digit display (LCD). The operating
voltage of DC 3 V is supplied by a lithium battery. The IrDA interface for automatically
reading out the readings is located beneath the display. The calculator on the flow me-
ter can be rotated 360°.
The temperature sensors can be installed either indirectly or directly immersed.
The sensor comprises the protection sleeve at the end of which is the measuring ele-
ment Pt 1000 and the PVC cable that connects it (fixed) to the calculator.
The temperature sensors are mounted in the ball valves with the temperature sensor
seat either (directly immersed) or in Tee with immersion sleeves (indirectly immersed).
Mounted (fixed), approved, pairs of and certified temperature sensors are used.
