About this document 1. 1 This manual describes the FLOWSIC600 measuring system, which is used to determine the volumetric flow rate, volume and speed of sound in gases transported in pipelines. It provides general information on the measuring method employed, design and function of the entire system and its components, on planning, assembly, installation, calibration com- missioning, maintenance and troubleshooting.
● Do not expose the equipment to mechanical stress, such as pigging. ● The flooding of the FLOWSIC600 with any liquid (e.g. for pressure or leakage tests) is deemed improper use. The consequences of such actions can not be foreseen or estimated.
Read this section and the notes and warnings in the individual sections of this manual carefully and observe the instructions contained therein when carrying out any work on the FLOWSIC600 measuring system.
Important Information Dangers due to heavy loads 1 . 7 The FLOWSIC600 measuring system must be safely attached to the carrying structure when being transported and installed. WARNING: ● Only use lifting gear and equipment (e.g. lifting straps) which is suitable for the weight to be lifted.
Features and applications 2. 1 System features The FLOWSIC600 measuring system is a compact gas meter used for ultrasonic volumetric gas flow measurement. It is available in several different path configurations. Some configurations have a redun- dant measuring system which includes a second Signal Processing Unit (SPU) to allow for independent measurements on the secondary paths (...
Product Description Applications The FLOWSIC600 is ideally suited for a wide range of custody transfer and process measurement applications; ● Production, transportation and distribution of natural gas, ● Company-internal metering and billing, ● Power stations and other gas-consuming installations, ● Chemical and petrochemical industries, ●...
Measuring principle 2 . 3 The FLOWSIC600 operates by measuring the propagation delay of an ultrasonic pulse. The standard 4-path meter is equipped with four pairs of identical ultrasonic transducers. The transducer pairs are integrated in a meter body and arranged opposite one another at a defined angle to the flow axis, thereby forming a direct measuring path (...
2.3.1 Measuring cycle In the operating status "Measurement", the FLOWSIC600 determines the gas velocity on each path 10 times per second. One measuring cycle consists of a velocity measurement per path, the integration of the operating volume, several internal procedures and the update of the measured value output channels.
K are nominal size-dependent constants which were determined by the manufacturer and which are related to a particular FLOWSIC600. Correcting the impact of pressure and temperature on the geometry of the meter body The geometry parameters of the meter body are based on ambient temperature of 20 °C and 1 bar(a) and have been optimized to minimize deviations due to the influence of pressure and temperature.
2. 4 NOTICE: Type approval A 4-path FLOWSIC600 is able to compensate for the failure of one or more paths using a static or an adaptive compensation routine as described below. Path failure may be caused by a received ultrasonic signal which is invalid, i.e.
Page 29
Because the path compensation procedure operates in a low (1 to 8 m/s or 3.28 to 26.24 ft/s) and a high (>8 m/s or >26.25 ft/s) gas velocity band separately, the FLOWSIC600 needs to measure 20 minutes within the low and 20 minutes within high velocity range.
2. 5 Hardware variants and signal outputs (I/O configuration) 2.5.1 The outputs of the FLOWSIC600 can be configured in several ways. Different output config- urations require different hardware variants of the electronic unit ( pg. 33, Table 3 and Table 4).
Optional integrated Electronic Volume Corrector (EVC) 2.5.2 The FLOWSIC600 (firmware V3.4.00 or higher) can be ordered with an integrated electronic volume corrector (EVC). On request and for extra charge, the EVC feature can be activated in the field. Please contact your local representative.
Status: Measurement valid 2.6.2.1 The meter status "Measurement" is the standard meter status of the FLOWSIC600. Frequency outputs and current output are updated cyclically and indicate the actual volume and volume flow rate. In addition, the analog signal can indicate the actual flow rate, corrected volumetric flow rate, SOS (speed of sound) or VOG (velocity of gas).
Product Description Data handling in the FLOWSIC600 2 . 8 Integrated volume counters 2.8.1 The FLOWSIC600 is equipped with integrated volume counters which can be displayed both on the LCD display and in MEPAFLOW600 CBM. Integrated volume counters Volume counter Abbreviation...
"Data invalid" is activated. The measured values are now counted in the error volume counter. If the FLOWSIC600 is not configured as a custody meter, all logbooks are per default con- figured to be overflowing. This means the index number continues increasing, and after the logbook has reached its maximum number of entries, each new entry overwrites the oldest entry.
Page 47
Product Description Logbook entries In MEPAFLOW600 CBM Logbook entries on the FLOWSIC600 can be downloaded, viewed, saved and exported with the MEPAFLOW600 CBM software. The "Meter logbook" page provides information on the number of registered events and the remaining memory space. See pg. 176, 6.4.1 on handling the logbooks with MEPAFLOW600 CBM.
DataLogs 2.8.3 For firmware version 3.4.03 and higher, the FLOWSIC600 provides two DataLogs (Hourly Log and Daily Log). They save averaged measured values and are stored in the SPU‘s non- volatile memory (FRAM). All data can be downloaded and exported to Excel files with MEPAFLOW600 CBM (...

4.2.1 General requirements: ● The FLOWSIC600 can be installed in customary straight inlet and outlet pipes. The adjacent pipes must have the same nominal size as the meter body. The internal diameter can be obtained from the table ( pg. 216, Table 29) based on the flange rating and the Standard.
Page 100
Two straight pipes are to be installed in the inlet and outlet sections if the meter is to be used bidirectionally. The temperature measuring point is to be located downstream of the FLOWSIC600, seen in the direction of predominant use. The temperature measuring point must not be installed more than 8 DN from the meter.
An arrow on the meter body indicates the main direction of flow. It is recommended to install the FLOWSIC600 as indicated by this arrow if the meter is to be used for unidirectional flow applications. If the meter is to be used in the bidirectional mode, the arrow indicates the positive direction of flow.
Wiring work (routing and connecting the power supply and signal cables), which is necessary when installing the FLOWSIC600, is not included in the scope of delivery.

VOG for warnings" or "VOG limit" will clear all data from the Diagnostics Comparison Log! ●...
Activation of path compensation 5. 8 If the status bit "Path compensation valid" is "active", then the FLOWSIC600 is able to compensate a path failure (see also pg. 28, 2.4). The meter automatically sets this bit to "active" after operating for about 20 minutes with error free measurement at all paths at a gas velocity between 1 to 8m/s (3.3 to 26.2 ft/s)
General 6. 1 The FLOWSIC600 does not contain mechanically moving parts. The meter body and ultra- sonic transducers are the only components that come into contact with the gaseous media. Titanium and high-quality stainless steel ensure that these components are resistant to corrosion, provided that the meter is installed and operated in accordance with the relevant specifications.
Routine checks 6 . 2 The information displayed on the front panel LCD display of the FLOWSIC600 meter can be checked to ensure that the system is functioning properly. The MEPAFLOW600 CBM soft- ware provides a more user friendly way for doing routine checks.
Page 170
If the SOS calculator was started from the Maintenance Report, the calculated value is automatically copied to the corresponding field in the wizard and to the report. Compare the theoretical SOS with the SOS measured by the FLOWSIC600 (see Figure 80, main system bar).
Checking the meter health 6.2.2 The FLOWSIC600 monitors its own meter health with User Warnings and system alarms. If the outputs are configured to indicate alarms and / or User Warnings, it is not necessary to manually check the meter health.
Synchronization via MODBUS The date and the time of the FLOWSIC600 can be set separately by an external write. Each operation for date and time causes a separate entry in the Custody logbook [1]. Alternatively the synchronization function can be used. To use this method, the date (Reg.
Battery lifespan / capacity 6.2.4 The Real Time Clock (RTC) of the FLOWSIC600 is buffered by a battery. The manufacturer states that the battery life span is at least ten years. The remaining battery capacity can be viewed on the LCD in the first menu level ( pg. 222, 9.3.2).
DataLogs check 6.4.2 Starting with firmware version 3.4.00, the FLOWSIC600 provides two DataLogs (Hourly Log and Daily Log). They save averaged measured values and are stored in the SPU‘s non- volatile memory (FRAM). All data can be downloaded and exported to Excel files with MEPAFLOW600 CBM (...
