SITRANS FUE950 energy calculator
Data logger memory (LOG)
■ Design
SITRANS FUE950 has an easy-read 8-digit LCD display with associated pictograms for the various functions. As the display has
been made for several applications, some figures/symbols not
used for normal district heating applications will be shown.
SITRANS FUE950 has a push button for simple operation and
provides user-friendly control via the various display menu
loops. The display will always be configured for the application
chosen, and for the selected display settings.
The integrator has an IP54 plastic housing and is designed for
wall or panel mounting. The housing comes with prepared rubber gaskets cable entries for fast and easy installation.
The LOG of the calculator is stored every 24 hours with all cumulative values in the EEPROM. The storage frequency can be selected from various storage intervals (5, 6, 10, 12, 15, 20, 30, 60
minutes or the default setting of 24 hours). The data which are
stored in the LOG could be read out using a software tool and
can be used for evaluations.

Operation menu loop structure

The FUE950 display has six menu loops and the menus are numbered in the display from 1 to 6. Some display menus consist of
two values (to maximum seven) that are shown alternately at 4second intervals.
24 hours
(default setting)
The main menu loop no. 1 with the current data, e.g. for energy,
volume, flow rate and temperature, is preprogrammed as default
setting.
In the combined heating/cooling configuration the menu loop no.
5 (tariff menu loop) will be activated additionally.
Display and output pulses
Units: MWh, GJ, Gcal, MBtu, m3, gal, m3/h, GPM, °C, °F and kW;
all decimal points are statically (the unit "gal" is shown with factor
x 100).
The display unit and the last fractional digit are typical used for
the pulse outputs.
■ Function
Technical principle
Calculation of energy is based on the following formula:
Energy = Volume x (THot - TCold) x Kfactor (Ti)
Volume: Volume [m3] of a given amount of volume pulses
THot: Measured temperature in the hot line
TCold: Measured temperature in the cold line
Kfactor (Ti): Thermal coefficient of media enthalpy and heat
content
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 seconds. If the connected flowmeter has not sent
enough pulses the energy calculation and flow indication is also
based on the 8 seconds value.
Data memory
The FUE950 has a history memory of 24 periods (months,
weeks, days). The following values are stored monthly, weekly or
daily in the EEPROM on the programmed day of 1…31 (via software tool).
• Date/Time
• Volume
• Energy
• Error day counter
• Tariff energy 1
• Maximum monthly flow rate
• Tariff energy 2
• Maximum monthly power
• Tariff definition 1
• Date of maximum monthly flow rate
• Tariff definition 2
• Date of maximum monthly power
• Pulse counter input 1
• Pulse counter input 2
Maximal Values
The integrator creates max. values for power and flow rate
based on consumption time, which are stored in the EEPROM.
The integration intervals are adjustable to 6, 15, 30 or 60 minutes
and 24h. Default setting is 60 minutes.
Tariff/Accounting date function
The calculator includes two independent memories in which the
accumulated energy at two programmable tariff dates are
stored.
• Last accounting date
• Last but one accounting date
Values stored
• Energy
• Volume
• Tariff counter 1
• Tariff counter 2
• Pulse counter 1
• Pulse counter 2
• Date
The integrator offers two optional tariff memories for monitoring
plant load states. Here it concerns threshold value tariffs. Extensive tariff conditions make it possible to adapt the calculator individually to the required customer-specific applications.
Both tariffs are separately configurable and independent from
each other. Energy or time can be measured alternatively per
tariff register dependent on the tariff mode adjusted in each
case.
With the "time triggered tariff function" the switch-on time and the
switch-off time are adjustable independent from each other for
each day of the week in steps of 15 minutes.

Error handling and memory
Events such as changes and faults are stored in a non-volatile
memory with a capacity of up to 127 entries. The following
events are recorded:
• Checksum error
• Temperature measurement error
• Error hours
• Start and end of test mode
If SITRANS FUE950 records an error, this will be automatically indicated by a "alarm symbol" on the display.
To protect the reading data, all the relevant data are saved in a
non-volatile memory (EEPROM). This memory saves the measured values, device parameters and types of error at regular intervals.
The following events are recorded:
• Temperature sensor error
• Swapped hot and cold temperature sensors
• Battery low warning
• Power supply failure
• Optical communication warning
• RAM checksum error
Outputs/Inputs/Communication
Communication interfaces:
SITRANS FUE950 is fitted with an optical infra-red send/receive
port in accordance with EN1434/IEC 61107, protocol standard,
EN 1434/EN 60870-3 (M-Bus protocol).
A specific optical head with a permanent magnet (IrDA-adapter)
in accordance with EN 1434 can be used for readout data or
communication with the parameterization software.
2 ports for optionally plug-in modules
The calculator features 2 ports for the plug-in modules.
One slot is for the function modules and the other for the communication modules.
Communication modules
The following communication modules are available as options:
RS 232 module, RS 485 module and M-Bus module. The RS 232
and RS 485 communication modules are serial interfaces and
permit data exchange with the calculator. For this purpose a
special data cable is necessary.
The M-Bus module is a serial interface for communication with
external devices (M-Bus Master/Centre). According to the
M-Bus structure a number of calculators can be connected to a
control centre.

■ Application
The temperature sensor set is designed for use with the
Siemens energy calculator type SITRANS FUE950 for measurement of the energy consumption in a district heating or cooling
net.
Permissible temp. pair range for T
• Heating
3 ... 150 K
• Cooling
3 ... 85 K
Temperature sensors are one of the integral components of every thermal energy meter in heating or cooling applications.
They are used for determining temperature changes in fluids
due to energy taken from or supplied to the loop. The temperature is thus measured by mounting temperature sensors upstream and downstream from the point where the exchange in
the thermal energy of the system is.
Medium
Approved for heating/cooling
water
Protection
IP65
To ensure an accurate measurement of the temperature difference according to MID (EN 1434) or PTB K7.2 the sensors are
delivered as matched pairs.
By selection with the corresponding Order code the Pt500 sensor pair sets can be delivered with heating approval or with approvals for combined heating/cooling applications.

Flow input setting (IN0)
The pulse input value selection must be the same as the pulse output setting of the selected flowmeter.
To get optimal function and performance the pulse value must be selected as low as possible according
to the maximum flow rate.
The following calculation formula can be used for determining the lowest pulse value at a pulse length of
5 ms: L/pulse > Qmax (m3/h)/360.
For example Qmax = 300 m3/h; L/pulse > 300/360; L/pulse > 0.83; therefore the pulse value must be
1 l/pulse.
