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.

Область применения

The SITRANS FUE950 is able to handle 3 kinds of applications, means energy calculation in:

District heating applications
Chilled water applications
Combined cooling/heating applications

Energy metering in heating, hot water applications (code "A" and "B")

Energy metering in cooling, chilled water applications (code "C" and "D")

Energy metering in combined cooling/heating applications (code "E" and "F")

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 (T_Hot - T_Cold) x K_factor (T_i)

Volume: Volume [m³] of a given amount of volume pulses

T_Hot: Measured temperature in the hot line

T_Cold: Measured temperature in the cold line

K_factor (T_i): 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
Operation hours

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	Error status Overload time temperature Overload time flow rate Forward temperature Return temperature Date and time Energy Tariff energy 1 Tariff energy 2 Tariff definition 1 Tariff definition 2 Volume Error day counter	440	36.6 hours
15 minutes		440	110 hours
1 hour		440	18.3 days
24 hours (default setting)		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

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
