Measurement concept of GasLab Q2 3 Measurement concept of GasLab Q2 3.1 Description of main features The Elster GasLab Q2 is a real-time natural gas analyzser. It determines the calorific value, Wobbe index and other parameters in natural gas. The applications of the device range from fiscal energy metering to measurement, control and regulation.
Measurement concept of GasLab Q2 3.2 Description of the operating principle The operating principle is based on the context of the gas quality characteristics heating value, density at base conditions (rho) and carbon dioxide content with various physical quantities of the gas.
Page 18
Measurement concept of GasLab Q2 Figure 3.2: Infrared measurement principle All significant hydrocarbon components in typical natural gas can be detected by IR absorption. The contribution of the hydrocarbon content can be determined for gas specifications such as gas heating value, density or heat conductivity, by using the IR absorption. The method additionally uses a thermal conductivity detector (TCD) in parallel.
Measurement concept of GasLab Q2 3.3 System setup A typical setup consists of a sample line from the gas pipeline to the analyzer. The measurement is made rapidly and continuously. A gas stream is fed to the measuring device from the pipeline, measured and fed into the exhaust tube.
Structure of GasLab Q2 Structure of GasLab Q2 The entire Q2 measurement system is completely integrated in a two-part aluminum housing. Both housing parts are connected mechanically by screws and electrically by a cable bushing. From a functional perspective, the hardware can be divided into three areas; the instrumentation area (highlighted yellow in the following overview), the connection area (highlighted orange) and the user operating interface highlighted in green (HMI).
Structure of GasLab Q2 4.1 Instrumentation area The instrumentation area contains gas-bearing parts and can be divided into the 2 functional modules GASM (Gas Management) and SENS (Sensor Device). The GASM area consists of the gas lines in the functional housing partand of the gas channel switching, the double-block-and-bleed-valve block.

Structure of GasLab Q2 4.2.2 Electrical entries and connections There are four holes for all electrical purpose (power, communication and I/O services) on top of the device. These electrical entry holes provide a M20x1.5 thread (see figure 4.4). Optionally ½” NPT thread via adapter is possible, please contact Elster for details. These holes have to be equipped with with blind plugs, adapters or cable feedthroughs.
Structure of GasLab Q2 4.3 Human machine interface (HMI) The actual interface with the human being primarily con- sists of an LCD display and a capacitive touch foil located directly behind glass window. The window can be covered with a screw cap which offers sand protection in an erosive environment (see Fig.

Commissioning and decommissioning Commissioning and decommissioning This chapter briefly describes the main points for the commissioning and decommissioning of the measurement device. All newly delivered devices already have a basic or factory setting so they can perform the measurement task. If necessary, customer-and system-specific settings have to be made.
Commissioning and decommissioning 6.2 Start-up and normal operation If the device is supplied with electric power, the start-up procedure begins automatically. The first step is the booting of the computer and the heating of the sensor block. The current temperature of the sensor block (called TSB) is displayed during this time on the display that appears.
Commissioning and decommissioning 6.2.1 Checking and adjusting the gas flows If you have done commissioning (steps 1 to 6 for start-up) and the right LED of the device is flashing red, you have to customize the flow of the process gas. Given that the local conditions are unknown and may differ with regard to the factory settings, it is possible that the internal pressure is not sufficient.
Commissioning and decommissioning 6.3 Decommissioning Without external power supply nor from the backup battery, data will be lost (e.g. archived data, device time setting) The device will not start correctly without support from Elster GmbH. Please proceed in the following order if you want decommissioning the GasLab Q2 and reuse it later in another location: Steps for decommissioning Turn off the power supply and secure it against turning back on.

Operation and parameter setting on the PC with enSuite 8.3.4 Change automatic operational calibration To ensure measurement accuracy, Q2 is calibrated with a base calibration in the factory prior to delivery and further checked and corrected during operation. This is ensured by the automatic operational calibration once a week and an annual service calibration.
Operation and parameter setting on the PC with enSuite 8.3.5 Reset all parameters to default condition If the device does not achieve acceptable results, e.g. by several incorrect settings, it may be necessary to restore an older parameter setting, or the default condition This procedure should only be used in emergency situations when all other options have been exhausted.
Operation and parameter setting on the PC with enSuite On the right side of the parameterization window, various settings and options are offered on tab Basic display editor • Basic display With the two selection menus, you can specify which display / sub display is the device first displays when switching on or reboot.
Operation and parameter setting on the PC with enSuite 8.4.3 Set time-related values and actions in the Time Service SFB Apart from the date and time you set any other time-related values and timed actions in the Time Service SFB as device parameterization. The online help provides information about the necessary parameters to adapt.

Operation and parameter setting on the PC with enSuite Save your changes to the parameterization and transfer the changed parameterization in the device. Then the user can login and perform actions with these rights. There is no default password assigned, also a newly created user has no password.
Operation and parameter setting on the PC with enSuite 8.4.5 Functions “Read out archives” and “Show archives” All relevant data can be logged in archives. In addition to the three permanently available archives „Audit trail (system)“, “Audit trail (fiscal)“ and “Logbook”, further archives may be created on the parameterization in Archive AFB.
Page 113
Operation and parameter setting on the PC with enSuite The archives window appears and shows the contents of the selected archive in a table and (if possible and chosen) in a chart. The ordinal number and the archiving time are displayed on the left. In the further course of the line, the archived data appears.
Operation and parameter setting on the PC with enSuite 8.4.6 Function “Live data and trending“ With this function EnSuite offers the possibility to view live data of the device shown as numerical value and graphically . First of all, you need a connection to the device ( See chapter 8.1.2). After you have gained access to the Q2, you can right-click on the Q2-symbol (on the left hand side window).

Operation and parameter setting on the PC with enSuite If you want to see a computed value e.g. the heating value (inferior calorific value) you have the option to view all 3 different states of the gas (completely dry / completely wet / partly wet). When you drag the desired values from the right window to the middle window, just press the “Poll”...
Operation and parameter setting on the PC with enSuite 8.4.7 Use approval file (optional) For devices that are to be used in fiscal metrology, a file in the device called “Approval file” gives an order which parameters are fiscal relevant and monitors these parameters for any changes. There are different country-specific approval files, which shall determine the parameters and the corresponding values to be monitored.
Maintenance and repair 9 Maintenance and repair To ensure long-term use of the device, a regular weekly operational calibration (see chapter 8), a yearly service calibration with maintenance / cleaning and if required a repair is necessary. The Elster GmbH recommends to document carrying out of service calibrations, maintenance work and the operation history.
Maintenance and repair 9.2 Repair and Elster service work The device has hardly any consumption and wear parts, but to maintain the accuracy of the measurement an annual service calibration with special gases is necessary. Elster GmbH also recommends an annual check of the filter in the process gas inlet in order to prevent errors.
