What is the Elster QA100 gas meter used for?

The Elster QA100 is a mechanical gas meter designed for utility billing and industrial process monitoring. Rated to 160 m³/h with ±1.5% accuracy, it measures natural gas, town gas, methane, and inert gases in applications requiring SCADA integration and automated data collection via Namur, optical, or M-BUS outputs.

What are the specifications of the Elster QA100 DN80 counter?

The QA100 DN80 features a maximum flow rate of 160 m³/h, pressure rating of 16 bar PN 16, accuracy of ±1.5% across the 0.2 Qmax to Qmax range, aluminium housing, and mechanical totalizer. It complies with DVGW, DIN EN 50227, and EN 1434-3 standards and supports Namur E200, optical, M-BUS, and L-BUS outputs.

Where can I buy the Elster QA100 gas meter in Singapore?

3G Electric, an authorised Elster distributor since 1990, supplies the QA100 DN80 counter throughout Singapore and Southeast Asia. We handle all logistics, customs clearance, and door-to-door delivery, with lead times available on request through our technical sales team.

How do I select the right gas meter output for my application?

Choose Namur E200 for relay-based legacy SCADA systems, optical interface for isolated meter reading, or M-BUS/L-BUS for modern networked billing and monitoring. Confirm your control system's protocol compatibility before ordering; 3G Electric's engineers can advise on output selection for your flow range and integration requirements.
