Safety notes
2.2 Lithium batteries
2.2 Lithium batteries
Lithium batteries are primary power sources with high energy content designed to represent
the highest possible degree of safety.
WARNING
Potential hazard
Lithium batteries may present a potential hazard if they are abused electrically or
mechanically. This is in most circumstances associated with the generation of excessive
heat where internal pressure may cause the cell to rupture.
Thus the following basic precautions should be observed when handling and using lithium
batteries:
•Do not short-circuit, recharge or connect with false polarity.
•Do not expose to temperature beyond the specified temperature range or incinerate the
battery.
•Do not crush, puncture or open cells or disassemble battery packs.
•Do not weld or solder to the battery’s body.
•Do not expose contents to water.
2.3 General requirements
The label seal on the calculator (see figures (Page 49)) must not be damaged!
A damaged seal will result in immediate invalidation of the factory warranty and calibration.
Siemens accepts no liability for amendment of legal metrological data if the seal has been
broken.
The cables supplied with the calculator must not be shortened or altered in any other way.
Note
All regulations on the use of calculator must be observed!
All regulations on electrical installations must be observed!
All instructions listed in the data sheet of the calculator must be observed.
The medium is fixed to water (or - as special option - for glycol additive) with specified
consistence.
Note
Calibration/verification
SITRANS FUE950 is a calorific energy meter ready for verification in accordance MID
approval according to European norm EN 1434.
Calibration marks on the calculator must not be damaged or removed! Their removal
invalidates the warranty and calibration of the meter. Label seals may only be removed by
authorized persons for servicing purposes and must then be renewed.

Description
SITRANS FUE950 is a universal thermal energy calculator, which meets the requirements of
EN1434 and has the MID approval for heat metering.
The SITRANS FUE950 energy calculator has been developed for Siemens Flow
Instruments.
Further, the energy calculator has been specially developed to receive volume pulses from
flowmeter type SITRANS FUS380/FUE380 or alternatively SITRANS F M MAG 5000/6000
transmitter. Typically it is used with the SITRANS F US flowmeter programme for energy
custody transfer in district and central heating systems, in which the medium is water with
temperatures up to 190 °C, or in cooling systems using water as coolant.
The energy calculator is modular in construction and can be fitted with optional modules
depending on the application. SITRANS FUE950 can be used for up to 9 999.9 m3/h.
3.1 Measuring principle
Energy calculation
Calculation of energy is based on the following formula:
Energy = Volume x (THot - TCold) x K-factor(Ti)
Volume: Volume [m3] of a given number of volume pulses from the flow meter (e.g.
SITRANS FUE380)
THot: Measured temperature in hot line (by the one of the Pt500 sensors)
TCold: Measured temperature in cold line (by the other Pt500 sensor)
K-factor (Ti): Thermal coefficient of media enthalpy and heat content (typical media is water)
The energy calculation is made by a counter and depends on temperature difference, pulse
input frequency and legal requirements.
The calculator always carries out at least one energy calculation every 2 sec. If connected
flowmeter has not sent enough pulses, energy calculation and flow indication is also based
on the 2 sec. value.

3.2 Applications
3.2 Applications
Heating and cooling applications
SITRANS FUE950 is able to perform energy calculation in 3 kinds of applications:
● District heating applications
Figure 3-1 District heating applications with flowmeter in cold line
● Chilled water applications
Figure 3-2 Chilled water applications with flowmeter in hot line
● Combined cooling/heating applications

Description
3.3 Design
The separate flowmeter for the input of volume pulse can be installed in hot or cold line.
Hot line is pipe with higher media temperature. In heating systems called forward line.
Cold line is pipe with lower media temperature. In heating systems called return line.
In cooling applications forward/return lines are the other way around.
3.3 Design
Display and push button
SITRANS FUE950 has an easy-read 7 digit LCD display with associated pictograms for
various functions. As display has been designed for several applications, figures/symbols not
used for normal district heating applications will appear in display.
Figure 3-4 SITRANS FUE950
Energy calculator has a SIMPLE OPERATION push button and provides user-friendly
control of various display menu loops.
Display will always be configured for a specific application, and for selected display settings.
In normal operation menu loop, display will show cumulative current energy values.
Integrator has an IP54 plastic housing designed for wall or panel mounting. Housing comes
with prepared rubber gaskets cable entries for fast and easy installation.
Temperature sensor set
Temperature sensor set is designed for use with Siemens energy calculator type SITRANS
FUE950 for measurement of energy consumption in a district heating net.
To ensure accurate measurement of temperature difference according to MID (EN 1434)
sensors are delivered as matched pairs.
Sensor sets can always be delivered with MID (EN1434) approval for multiple-purpose
applications in heating applications.
