1 Tim Vogel 26 September 2017 GAS VOLUME CONVERTERS THE BRAIN OF GAS DISTRIBUTION METERING STATIONS

2 AGENDA 1. Volume Conversion why and how? 2. Introduction to Elster Volume Converters 3. How do I choose the right product? 4. Current Market Trends and how Honeywell addresses them 5. Market Feedback Session we want to know what is important to you LET S SEE HOW LONG WE CAN KEEP YOU AWAKE

3 Volume Conversion Why and How? Why? Gas meters measure the gas volume always at measurement condition. But gas pressures and temperature are always different. To make the measured volume comparable for billing purposes it has to be converted to given standard conditions. How? V b A volume converter = V m Tb T p 1 P K b V b takes pulses (as consumption information) from a mechanical gas meter which represent the volume at measurement conditions V m Measures the gas pressure p and temperatures T frequently convert the volume to standard conditions V b The compressibility K is used to compensate the deviance of the thermodynamic properties of a real gas in relation to an ideal gas K V m p T

4 Elster Volume Converters 3 What Are We Selling? EK280, EK220, EK205 Where Are We Selling? Key Sub-Verticals DL230 Volume Converter EK-Series (and Data Loggers DL-Series) as single devices and also in combination with meters Production Processing Storage Pipelines Distribution Major Applications Main focus on Gas Downstream (Distribution, Industrial, Power) Volume Conversion in small and midsize C&I stations mainly for billing purposes Station monitoring in combination with SCADA Systems Recording consumption and peak load data for custody transfer (Data Loggers DL-Series)

5 Volume Conversion And More! EK280 Core function is volume conversion... EK220 but this is not enough nowadays. EK205 So these devices also provide: Flexible data logging Audit trail and logbooks Additional inputs Digital outputs Data Interfaces Options for additional sensors Options for communication modules

6 EK-Series Product Portfolio EK220 EK220 EK205 PTZ, PT and T Converter for custody transfer for standard applications just volume conversion often in combination with meters (tender) prepared for data communication provides different protocols (e.g. Modbus) serial interface to connect com modules EK280 PTZ Converter for custody transfer including data communication provides different protocols (e.g. Modbus) com module can be integrated (option) software download acc. WELMEC including station monitoring use of additional Inputs/Outputs use of additional Sensors (option) use of applications (e.g. flow monitoring)

7 EVCS and More Function Extension Unit and Data Loggers EK220 FE260 Function Extension Unit Accessory for EK-Series Ex-barrier for interface and outputs Interface for communication modules Intrinsically safe power supply Com Modules (e.g. GSM/GPRS) DL230 Recording consumption and peak load data for custody transfer Where Volume conversion is not needed or in combination with existing EVCs Com module integrated Battery or mains supplied Designed and PTB approved for smaller C&I meters (low pressure) especially in Germany

8 EK280 Additional Benefits for Customers Conversion and Monitoring with one device 2 nd T-sensor (Option) 2 2nd p-sensor (Option) Filter Differential pressure switch Inlet pressure Regulator (Slam shot valve SSV) Up to 5 status inputs 3 1 V m LF/ HF/ Encoder p T Billing Via GSM/GPRS Modem Monitoring via interface to SCADA system Volume Conversion metrological core function Data communication meanwhile mandatory and integrated Monitoring additional functions already included

9 EK-Series Well Accepted EK220 because More than 15 years experience Installed-based over Units Best price/performance ratio Reduces TCO Total Cost of Ownership High accuracy Long-term stability Most flexible in use Powerful software tool Certified by: Approved by:

10 Ensuite - Configuration Software Administration, configuration, maintenance of the devices Local and remote connection Read out and evaluation of process and historical data Flexible export functions Supports 5 languages POWERFUL SOFTWARE TOOL SIMPLIFIES THE HANDLING

11 Why Move from EK220 To EK205? 10 Excellent cost position by excellent quality and performance EK220 Successor for standard applications EK205 Features: 3 inputs / 4 outputs Internal p sensor Serial interface RS232/485 Modbus communication Flexible archives ATEX and IEC Ex approved like EK220 limited to standard application means 2 inputs / 2 outputs But additional advantages: Graphical display Remote software update Quicker installation Automatic protocol detection EK220 will be only offered when features or customer approvals do not permit EK205

12 EK205 The New Standard For Standard Apps 11 Why is the EK205 the better offering? Compact design Fit s perfectly to Elster RABO and all other meters Quicker installation no earthing, no shielded cables Graphical display Vb and Vm are shown on the Display at the same time Non volatile data logger with bigger capacity Hourly values for more than one year Automatic protocol detection Modbus for SCADA and IEC for configuration Remote and local software update in acc. to Welmec 7.2 Without recalibration of the sensors

13 Europe is Going All-IP! 12 OPTION 1 OPTION 2 OPTION 3 Device is connected through analog phone line Device connected through Ethernet Device uses own modem to connect to head end system In Germany discontinued by 2018 Customers are already switching to IP Gas suppliers are depending on customer systems Possible to connect directly to an Ethernet network DSL-Connection or GPRS Router with Ethernet interface needed Depending on customer Mobile reception is needed Supplier is completely independent from customer What is the situation like in your country? Need to act?

14 2G / 3G Modems for EK280 and DL Old modem has been discontinued New Development with new modem chip from Swiss supplier Available for 2G (GSM/GPRS) and 3G (UMTS) connections Modem set is ready for 4G (LTE), change of modem module in the field necessary Available also in EK205 in 2018
