Обзор
SITRANS FUE950 is a universal thermal energy calculator, which meets the requirements EN 1434 and has the MID and PTB K7.2 approval for energy metering with the media water.
SITRANS FUE950 has been developed for the SITRANS FUS380/FUE380 and alternatively MAG 5000/6000 or FST020. SITRANS FUE950 is modular in construction and can by order be fitted with optional modules depending on the application. The FUE950 supports none of the SITRANS FX, FC products and only some of the FUS clamp-on products.
Дизайн
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.
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 4-second intervals.
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.
Displays 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.
Функции
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).

Data logger memory (LOG)
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.
Extract of possible LOG settings
Storage interval | Values | Number of data records | Recording period |
---|---|---|---|
5 minutes |
| 440 | 36.6 hours |
15 minutes | 440 | 110 hours | |
1 hour | 440 | 18.3 days | |
24 hours | 440 | 440 days |
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 24 h. 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.
The following tariff limit types of the tariff are possible:
(This example applies to the display at 3 fractional digits after comma)
Type | Description | Limit | Limit resolution |
---|---|---|---|
dT | Temperature difference | 1 … 190 °C | 1 °C |
-dT | Negative temperature difference | 1 … 190 °C | 1 °C |
TR | Return temperature (low) | 1 … 190 °C | 1 °C |
TV | Forward temperature (high) | 1 … 190 °C | 1 °C |
P | Power | 10 … 2500 kW | 10 kW |
Q | Flow | 1 … 255 m3/h | 1 m3/h |
FE | "Theoretically forward energy" with return temperature of 0 °C | ||
Z | "Time triggered" counting energy | ||
E | "External" counting energy |
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 EN 1434/IEC 61107, protocol standard, EN 1434/EN 60870-3 (M-Bus protocol).

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.
Pulse input module
Two pulse inputs are available. The pulse value and the unit is configurable for energy, water, gas or electrical meter by parameterization software. Data are separate cumulated in different registers and are also stored on the two accounting day''s (Tariff registers).
Combined pulse Input/Output module
Two pulse inputs combined with one pulse output are available on one module. The pulse inputs are configurable with value and the unit by parameterization software.
The pulse output is also programmable using the parameterization software.
Pulse output
The calculator provides levels for two optional external pulse outputs, which can be freely programmed using the parameterization software tool.
Default setting is one pulse which occurs per change in the least significant digit in the display with the unit and resolution selected by the device ordering.
