2.1.1Gas flow meter
The FLOWSIC500 works according to the principle of ultrasonic transit time difference
measurement.
Fig. 3Functional principle
Measured signal transit times tAB and tBA are defined by the current sound and gas velocity.
Gas velocity v is determined from the difference between the signal transit times. Therefore changes in the sound velocity caused by pressure or temperature fluctuations do not
affect the calculated gas velocity with this measurement method.
The FLOWSIC500 calculates the volume flow rate internally from the gas velocity and the
diameter of the measuring section of the gas flow meter.
Product Description
2.1.2Volume conversion (optional)
The integrated volume conversion converts the measured gas volume from measurement
conditions to base conditions.
Calculation according to EN 12405:
The measurement conditions are either determined with pressure and temperature transmitters or entered as fixed value.
The following short forms are used in this document for better readability:
● Volume at base conditions = base volume
● Volume at measurement conditions = measurement volume
● optional p&T sensors for the volume conversion device option.
Fig. 4FLOWSIC500 components
2.2.1
Adapter
The adapter is available in various flange standards and fitting lengths to connect the gas
flow meter to the system pipeline.
Depending on the version, the adapter is designed for assembly on line flanges PN16 in
accordance with DIN EN1092-1, CL150 in accordance with ASME B16.5, or 1.6MPa in
accordance with GOST 12815-80.
An internal flow conditioner rectifies the gas flow in the gas flow meter so that flow profile
disturbances caused by pipe bends in the inlet or outlet sections or components projecting
into the pipe (e.g., a thermowell) have no influence on measuring results.
The gas flow meter can be replaced without taking the adapter out of the pipeline.
The gas flow meter is fitted with:
● Control unit
● Optical and electrical interfaces
● Measuring cell with ultrasonic transducers
● Electronics.
The product variant with volume conversion and integrated pressure and temperature
transmitters also has the calibrated pressure transmitter and calibrated temperature
transmitter fitted in the gas flow meter.
2.3Meter sizes
Available meter sizes → p. 117, §9.4.
2.4Power supply
The FLOWSIC500 is available with two configurations:
● For operation with external intrinsically safe power supply with backup battery (backup
duration: Approx. 3 months).
● Self-sufficient power configuration: 2 internal longlife battery packs (typical service life:
At least 5 years).
The second battery pack is activated automatically when the first pack is empty and a
message displayed (→ p. 58, § 5.2).
Product Description
2.5Interfaces
The FLOWSIC500 supports various digital and serial interfaces.
The configuration of the interfaces as delivered is described in the delivery documents pro-
FLOWSIC500 has 4 digital switching outputs. Digital switching outputs DO_0, DO_2 and
DO_3 are electrically isolated according to EN 60947-5-6.
Alternatively, digital switching outputs DO_2 and DO_3 can also be configured as Open Collector.
When used as pulse output, maximum 2 kHz can be output on digital switching output
DO_0 and maximum 100 Hz on digital switching outputs DO_2 and DO_3. When used as
status output, status information "Validity of measurement" or the result of the self-diagnosis can be represented.
Digital switching output DO_1 is not electrically isolated. In normal mode, the diagnosis
warning is output on DO_1, test pulses are output in test mode.
The digital switching outputs are updated synchronously once per second.
2.5.2Encoder totalizer
Alternatively, NAMUR switching output DO_0 can be configured so that the reading of totalizer Vm, the meter status and a meter identification are output via asynchronous serial
communication. This allows the connection of volume convertors with a suitable input for
encoder totalizers.
NOTICE:
If encoder communication has been configured, ensure that the transferred
number of digits and the counter resolution can be processed by a connected
volume converter.
When the parameter locking switch is open, a parameter change can be performed at the FLOWSIC500 using the FLOWgate500 operating software.
2.5.3Serial data interface
The serial interface is designed as externally powered RS485 and requires an external
intrinsically safe power supply for operation. The RS485 interface has no internal line termination.
2.5.4Optical data interface
An optical interface according to IEC 62056-21 with serial bit, asynchronous data transmission is located on the front of the FLOWSIC500.
The interface can be used to read out data and parameter settings and to configure the
FLOWSIC500.
The FLOWSIC500 gas flow meter with volume conversion captures the gas volume under
measurement conditions and converts it to a volume under base conditions.
Gas volume conversion can run selectively (set at the factory) as PTZ or TZ volume conversion: The configuration as temperature volume conversion uses the default value for measurement pressure for calculations.
Measurement conditions are recorded with the pressure and temperature transmitters or
entered as fixed values.
By default, measured values recording and subsequent conversion to the volume under
base conditions are performed every 30 seconds. The update interval can be adjusted
→ p. 69, § 5.2.6.5, “Calculation”.
Depending on the configuration, the compressibility factor (K-factor) is determined with
one of the following calculation methods or can be entered as a fixed value.
● SGERG88,
● AGA 8 Gross method 1
● AGA 8 Gross method 2
● AGA NX-19
● AGA NX-19 mod.
● Fixed value
The FLOWSIC500 checks the permissible entry limits of the parameters for the selected
calculation method. If one of the entry values is outside the limit values, the FLOWSIC500
switches to malfunction state and uses the fixed value of the compressibility factor for calculation of the basis volume.
An absolute pressure transmitter EDT 23 (optional: relative pressure transmitter EDT 23)
and a temperature transmitter EDT 34 measure current measurement conditions and
transfer the transmitter type, measured value as well as the transmitter status via a digital
interface.
The FLOWSIC500 reads the valid measuring range automatically and, periodically, the current status and measured value.
A transmitter is only activated for measurement when the configured serial number
matches the serial number transferred for the transmitter.
If no transmitter is detected or a transmitter is not functioning correctly, the
FLOWSIC500 automatically uses the stored default value (= fixed value) of the state vari-
able.
In this case, the FLOWSIC500 switches to malfunction state and, using the default value,
stores the volume under base conditions calculated for pressure or temperature in the
error volume counter.
If not specified otherwise, the FLOWSIC500 is supplied with the following standard settings:

2.6.2Integrated pressure and temperature transmitters
The FLOWSIC500 with volume conversion and integrated pressure and temperature transmitters does not have any external components. The internal pressure and temperature
transmitters are already fitted and calibrated at the factory. The measuring ports are
located in the gas flow meter.
This means the FLOWSIC500 does not require any additional installation of transmitters to
determine the measurement conditions and is immediately ready for operation after volume conversion has been configured.
2.6.3External pressure and temperature transmitters
The FLOWSIC500 with volume conversion and external transmitters is used at measuring
ports where a test/calibration of the pressure or temperature transmitter in the system
may be required.
It is recommended to install a three-way test valve that separates the pressure transmitter
from the measurement pressure and provides a test connection to test the pressure transmitter.
→ Fig. 5 shows a FLOWSIC500 with external transmitters and Kamstrup test valve BDA04
for gas temperatures to -25°C.

2.7Totalizers
2.7.1Device status and totalizers used
Various volume totalizers are fitted on the FLOWSIC500 depending on the configuration.
Meter V is used in the configuration as gas flow meter. If the gas flow meter has a malfunc-
tion, the measured volume is also recorded in the error volume counter errV.

●●
A gas flow meter Vm, a base volume meter Vb and a total volume meter Vbtot are used in
the configuration as gas flow meter with integrated volume conversion (device option). If
malfunctions occur, the measured values are not recorded in the base volume meter Vb,
but the converted volume is recorded in the error volume meter errVb.

Operation
Malfunction
Authorized users (user level "Authorized user") can reset the error volume counters → p. 73,
The FLOWSIC500 is designed as unidirectional type and has a configurable zero-flow cutoff
which is factory set to a value of 1 m
The totalizers are stopped during reverse flow and this volume is counted in a separate buffer totalizer. When normal operation resumes, the buffer totalizer is first computed with the
flow.
The totalizers are first incremented again after the reverse flow volume has passed
through.
During reverse flow, the meter first switches to malfunction when the preconfigured buffer
volume has been exceeded. An error message is output on the device.
2.8Logbooks and Archives
The integrated data registration stores meter readings, maximums and other data in the
following archives:
● Measuring period archive
Totalizers and data saved after the measuring period elapses (standard = 60 min.). The
measuring period can be adjusted → p. 71, §5.2.6.9.
● Daily archive
Totalizers and data saved at the defined gas hour time (standard = 06:00)
● Monthly archive
Totalizers and data saved at the defined gas day time (standard = 1st day of month)

Explanations on data structure and storage depth are available in Technical
Bulletin "Data Registration").
The FLOWSIC500 stores events and parameter changes in the following logbooks:
● Event logbook
All events with timestamp, user logged on and totalizer reading, max. number of
entries: 1000
When the Event logbook is 90% full, the FLOWSIC500 changes to device status "Warn-
ing", warning W-2001 is shown on the display.
When the Event logbook is full, the FLOWSIC500 changes to device status "Malfunc-
tion", error E-3001 is shown on the display (→ p. 78, § 6.2, “Status messages”).
● Parameter logbook
All parameter changes with timestamp, user logged on, totalizer reading and old and
new parameter value, max. number of entries: 250
The oldest entries are overwritten when the Parameter logbook is full.
● Metrology logbook
All changes to selected calibration-relevant parameters (→ p. 24, §2.9.2), with parameter
locking switch activated with timestamp, user logged on, totalizer reading and old and
new parameter value, max. number of entries: 100
When the Metrology logbook is full, calibration-relevant parameters can be modified
only after the parameter locking switch has been opened. The FLOWSIC500 changes to
device status "Warning", warning W-2002 is shown on the display (→ p. 78, § 6.2, “Status
messages”).
Subject to change w ithout notice
The data are stored in non-volatile memory. All logbooks can be viewed, stored and reset
with operating software FLOWgate500. The Event logbook can be viewed after logon as
"User" or "Authorized user" on the device.
A parameter locking switch is located on the circuit board to secure the calibration-relevant
parameters. This covers all values that influence volume metering and volume conversion.
Fig. 7Parameter locking switch on the circuit board
Product Description
The parameter locking switch is secured by the terminal compartment cover and a seal.
2.9.2Metrology logbook
Selected calibration-relevant parameters can be modified when the parameter locking
switch is closed and after logging in as authorized user.
To ensure traceability of these parameter changes, an entry is created in the Metrology logbook. This entry contains the timestamp, old and new value of the parameter changed,
meter reading V (for gas flow meters) or Vb (for gas flow meters with device option volume
conversion) and the logged on user.
The Metrology logbook can have a maximum of 100 entries. The FLOWSIC500 switches to
status "Warning" when the Metrology logbook is full.
The Metrology logbook can be cleared when the parameter locking switch is open. Parameter changes to the following parameters are entered in the Metrology logbook as long as
entries are possible
