10 Diehl Gas Metering Static Gas Meter - Pressure independence - Temperature conversion Integrated Communication - Radio - M-Bus Product Portfolio Gas Center of Competence for Gas Measurement Diehl Gas Metering GmbH Industriestraße Ansbach Tel.: Fax: Diehl Metering10

11 Modern Gas Test Lab Unique real gas and endurance test benches all kind of gases -25 C° to +55 C° wide range of flow rates Approved as national authorized test lab for gas meters Diehl Metering11

12 AERIUS Diehl Metering12 For pressure independent and temperature converting standard volume measurements Domestic gas meter based on the microthermal measurement principle

13 Cross Section AERIUS Diehl Metering13 Gas outlet Particle rest area Gas inlet Cyclone filter Distributing chamber Cover plate Fire protection valve Body Measuring Unit Feed

14 Measuring Unit pressure dropper main channel measuring channel sensor By-pass Principle Diehl Metering14

15 Microthermal measuring principle Diehl Metering15

16 Animation Measuring Principle Diehl Metering16

17 Result of measurement is Standard Volume Microthermal Mass Flow Measuring Principle Q Sensor Heater Temperature max. 20 K Temperature Sensor 1 Temperature Sensor 2 ΔT max. 2 K Heating power: 2 mW Duration of measurement:50 msec Measurement interval: 2 s Gas molecules act as «heat-carriers» The heat transport of the gas stream is measured, which is corresponding to the mass flow No volume measurement Mass flow is a measure for the number of molecules (per time interval) Molecules are carriers of the thermal energy of the gas Diehl Metering17.. Thermal energy = c. # molecules. calorific value

18 Electronics (A/D-Converter) Sensor Heating Element Thermopile 2 Microthermal Mass Flow Sensor Thermopile 1 Absolute Temperature Sensor Diehl Metering18

19 Diehl Metering19 AERIUS Measurement Results ,010,1110 Fehler / % ISO H3 -25°C N2 -25°C CH4 -25°C ISO H2 -25°C 40 l/h600 l/h6000 l/h

20 Built-in Communication Interfaces Diehl Metering20 Wired M-Bus (EN 13757) Wireless M-Bus (EN 13757) Integrated radio interface 868 MHz 434 MHz OMS ® protocol AES-key (individually possible)

21 Bill kWh Diaphragm gas meter Assumptions: Temperature 15°C Air pressure 1016mbar Pressure in supply pipe 22mbar Calorific value kWh/m 3 relative to K and mbar Multiplication with the count and the condition number T-correction / = p-correction 1016 – (0.12 * m.ü.M.) condition number = * p-correction AERIUS Display in relation to: Temperature 0 °C Air pressure mbar condition number = 1 Domestic Gas Billing (example Germany DVGW G685) Diehl Metering21

22 AERIUS: Added Value Transparent gas billing for end customers through standard volume indication –Energy consumption: Standard volume output multiplied by calorific value Independent of –Atmospheric Pressure –Temperature Gas types –Natural gases of type H and biogas (methane CH 4 ) –Air Fraud Detection –Air detection Power Budget –Battery life time up to 20 years Repetitious, long-term stable and high accuracy of measurements –No moving parts –Wear-free –Small gas flows –Overload resistant Diehl Metering
