Mathema more hectic and subjected to more ticians will have worked out that Elster changes. This is no different in the gas has already added a further 10% to this industry and the companies working in in 2013 and that the 165th anniversary is this field. Its a good thing that we have upon us. Somehow I cant help feeling many new employees who readily take that as much has happened in these past on these changes and drive them for 15 years in the gas industry and at Elster ward. But it is also a good thing that we as during the preceding 150 years. have employees who have worked for us for much longer than these 15 years In the gas industry, we have seen the and who can keep our feet on the ground. change from municipal utility companies to The mix is important and we have a good grid operators, metering service providers mix at Elster. and energy distributors and to a certain extent back again.

3 A pplications 3 Elster-Instromet Profiles 2/2013 German premiere for bi-directional turbine gas meters: SM-RI 2 and Q.Sonic plus in bi-directional continuous series operation Turbine gas meters (SM-RI 2) are being used in Germany in bi-directional operation for the first time. In combination with our ultrasonic gas meter, Q.Sonicplus, measurement lines are being implemented that are virtually maintenance-free. This device combination fulfils the legal unlimited recalibration requirements of a series connection using two different physical measuring principles. A great advantage is that all the main worthy is the fact that the SM-RI 2 is the The maximum MID approved measuring assemblies and devices are supplied by first MID approved turbine gas meter for range for the SM-RI 2 in the 16 inch nom manufacturing companies of the Elster bi-directional operation in Europe. inal size is 320 to 16,000 m/h.

8 8 P roducts Elster-Instromet Profiles 2/2013 The right partner for improving your process Creating stable conditions Natural gas is a natural product which comes in a range of qualities and origins. The composition of the gas changes depending on the delivery situation of the utility companies. To keep the billing of the energy, in other words the natural gas, as accurate as possible, the gas must be measured continuously at the injection stations in the grid area concerned. The permitted natural gas quality is set out in DVGW Code of Practice G 260 Gas quality. According to this the grid calorific value may fluctuate between 8.4 and 13.1 kWh/m. Certain industries, however, are depen dent on a stable calorific value or Wobbe index of the natural gas. These industries include the glass and ceramics processing industries, brick works, roofing tile plants, etc. In other words, industries in which flames are the tool.. And this should be as precise as possible because the quality demands of consumers are constantly rising.

Since the announcement of feed-in tariffs for biomethane in France, Elster has been working on a grid injection package that meets the requirements of the French market. With the EnCal 3000 gas chromatograph as the heart of the system, Elster has won the tender for supplying grid injection systems to GrDF.

The Syndicate had been waiting for the regulatory legal texts allowing double energy recovery to be published so that it could benefit from the feed-in tariffs and begin operation of its production plant.
