About Elster
Elster manufactures turbine and rotary-displacement gas meters for industrial measurement and custody-transfer applications. The brand's product range spans from compact 1-inch models (QA10, QA16) rated to 16–25 m³/h through mid-range quantometers (QA100, QA160) handling 160–250 m³/h, up to large-bore meters (QA250, QA650) rated to 400–1000 m³/h at DN80–DN150. All meters are aluminum-bodied and rated to 16 bar (PN 16) or higher pressure classes, with ±1.5% accuracy and 1:20 measuring ranges typical across the QA series. Elster meters are designed for natural gas, air, methane, nitrogen, and other non-corrosive gases in utility, industrial process, and burner-supply applications. The QA series includes mechanical totalizers and optional output interfaces—Namur E200, optical (EN 1434-3), M-BUS, and L-BUS—enabling integration with building management and SCADA systems. 3G Electric stocks 18 Elster SKUs, including the MQM counter series (MQM10, MQM40) for smaller flows and the full QA quantometer lineup, providing same-day availability and technical support for engineers and maintenance teams selecting metering equipment for combustion-air measurement, gas-supply monitoring, and energy-audit applications across industrial and commercial plant environments.
Frequently asked questions
Common questions about Elster from 3G Electric.
What accuracy and pressure rating do Elster QA-series meters provide?
The QA-series quantometers (QA10, QA16, QA100, QA160, QA250, QA650) are rated to ±1.5% accuracy across their operating range (0.2 Qmax to Qmax). All models are rated to 16 bar (PN 16) as standard; larger models (QA650) support up to 20 bar (Class 150 pressure rating). This combination suits custody-transfer metering, industrial process control, and burner-supply monitoring where measurement certainty is required.
Which Elster meter models are suitable for small industrial burners and combustion-air lines?
The QA10 (16 m³/h) and QA16 (25 m³/h) are 1-inch compact meters designed for natural gas, air, methane, and nitrogen at flow rates typical of single or dual burner stacks. Both feature aluminum bodies, 1:20 measuring range, and optional Namur E200 or optical outputs. The MQM10 and MQM40 counter models (16 and 65 m³/h respectively) offer mechanical totalizer display for non-networked applications.
What output interfaces do Elster QA meters support for SCADA and BMS integration?
The QA100, QA160, QA250, and QA650 quantometers support Namur E200, EN 1434-3 optical interface, M-BUS (EN 13757-3), and L-BUS outputs. Smaller models (QA10, QA16) typically feature mechanical totalizer or single-pulse output. Output selection depends on building automation requirements; consult the detailed datasheet or 3G Electric technical team to confirm interface availability for your specific meter.
Are Elster meters suitable for gases other than natural gas?
Yes. The QA series is rated for natural gas, air, methane, nitrogen, and other non-corrosive gases. Turbine-type meters (QA10, QA16, QA250, QA650) are designed to handle a wide range of gas media, making them suitable for compressed-air measurement, nitrogen flow monitoring, and biogas applications in industrial plants. Consult product specifications to confirm compatibility with specific gases and pressure conditions.
What is the difference between Elster MQM and QA-series meters?
The MQM series (MQM10, MQM40) are compact counter-style meters with mechanical totalizer displays, suited to lower flows (16–65 m³/h) in applications where plug-in operation suffices. The QA series are turbine or rotary quantometers (QA10 through QA650) offering higher accuracy (±1.5%), wider measuring ranges (1:20), broader flow coverage (16–1000 m³/h), and flexible output options (Namur, M-BUS, optical) for utility billing and process control.
How does Elster meter sizing apply to industrial plant gas-supply lines?
Elster offers a continuous range: 1-inch DN25 models (QA10, QA16) for single-burner or low-demand lines; DN50–DN80 models (QA100, QA160, QA250) for multi-burner or mid-capacity plants; and DN150 (QA650) for large industrial sites. Select by maximum expected flow rate plus 10–20% headroom. 3G Electric can assist with sizing based on burner count, gas pressure, and process demand.
