Page 9: Introduction
1.1 The gas-net system idea is the generic term for an Elster device family. The evaluation computer of the gas-lab Q1, too, is based on the gas-net device family. All gas-net devices, including future device types, are characterised by uniformity in appearance, operation and parameterisation. - Page 10 The evaluation computer also controls the measuring process and calculates the target variables.

- Page 11 The device measures continually and determines new measurements every second. It can therefore also be used for fast closed-loop control tasks. The manufacturer calibrates the gas-lab Q1 before delivery, i.e. he performs a zero point adjustment with nitrogen and afterwards a 3-point calibration with ultra-pure methane and two calibration gases.

2 Device view and design 2.1 Sensor system The actual sensor technology of the gas-lab Q1, the sensor system, is mounted in an explosion-proof housing. The gas is supplied at approximately 80 mbars overpressure and via a double block & bleed solenoid valve set, which is also located inside the housing. - Page 14 Q1 Not only the sensor housing is installed on the mounting plate, but also regulators for the inlet pressure of the different gases to be injected, safety shut- off and safety relief valves as well as the EEx-e junction box for the interconnecting cables (voltage supply, data link to the evaluation computer).

The functionality of the Q1 can be completely configured via a parameter data record. Unauthorised persons must be prevented from changing these parameters. In order to guarantee this protection, the gas-lab Q1 is provided with a two-level security system consisting of the Calibration lock (official safeguarding) and the Locks (user lock, password protection). -

The following description assumes that you have chosen gas path 1 in step 4 (process gas path). Open the inlet valve of the process gas very slowly. The flow controller of the sensor system’s vent gas line must be set to 30l/h (top of ball). gas-lab Q1 Page 123... - Page 132 This waiting time can be adjusted. This is important for a redundant (double) installation of the measurement devices, since else both – e.g. after power failure – will calibrate at the same time and during this time none of both can be used. Please contact Elster for further questions.

Maintenance 9.2 Maintaining the gas-lab Q1 sensor system The sensor system does not require much maintenance and does not contain any wearing parts. Only methane is used for calibration during normal operation. The following tasks must be accomplished during the yearly routine testing: The calibration gas methane must be replaced if the residual gas volume has dropped below 200 nm³, which corresponds to a residual pressure of... -

10 Technical data: Q1 10.1 Device type The gas-lab Q1 measuring system is a flameless measuring instrument for determining the quality of natural gases using an infrared absorption-based measuring method. It consists of a heavy-duty housing, in which the actual sensor unit is accommodated, and of an evaluation computer, which must be operated in a non-hazardous environment. - Page 138 24 V DC ± 5 %, 2 A, power input: max. 50 W (cold start) normal 35 W Gas injection 3-channel double block and bleed valve block integrated in the sensor housing for the process gas and two calibration gases, vent line connection.

Annex 11 Annex 11.1 Error listing of the gas-lab Q1 The following list describes all error messages that may appear on the error listing of the gas quality measurement. Furthermore, the performance of the device when gas quality-relevant errors occur is explained. - Page 144 H2019 (Tmin startup) is generated. Another reason for the alarm is given when the temperature stability check during the start up fails, in this case H2020 (T instab startup) isgenerated. The measurement stops until the temperature is stable again. Page 136 gas-lab Q1...
