Overview of the Rabo Compact Gas Meter
The Rabo Compact Gas Meter stands out for its exceptional accuracy and space-efficient design. Built to handle a wide range of gas flow rates — including low and irregular flows — this meter leverages the most reliable technologies from previous generations of Elster-Instromet rotary gas meters. Its modernized features ensure compliance with future standards, making it a robust choice for diverse applications.
Positive Displacement Technology
At the heart of the Rabo Compact Gas Meter is the positive displacement principle, a proven method for measuring the volume of gaseous media. Thanks to this volumetric approach, the device delivers consistent readings unaffected by varying installation setups. This makes it highly suitable for systems that require compact configurations without long inlet sections. The meter measures the gas volume under actual operating conditions and is fully approved for custody transfer use.
Mechanical Structure and Function
The meter contains two precisely synchronized impellers shaped like a horizontal figure-eight when viewed from the side. These impellers are mounted within a single chamber that has a gas inlet and outlet. As gas flows through the unit, the impellers rotate in tandem — without making contact — to transport a known, fixed volume of gas per cycle.
Each full rotation of the impellers equates to a specific gas volume, allowing for precise measurement. The rotary motion is then relayed to the mechanical index through a system of reduction gears and a magnetic coupler. Fine-tuning of the reading is accomplished using adjustable gears within the index mechanism.
Volume Conversion Options
To enhance accuracy, especially in varying temperature and pressure environments, the Rabo Compact Gas Meter can be paired with electronic volume conversion devices. These devices adjust the measured gas volume to standard reference conditions, enabling precise billing and monitoring.
Why Choose the Rabo Compact Gas Meter?
Combining compact construction, mechanical precision, and future-proof features, the Rabo Compact Gas Meter is a reliable choice for gas volume measurement across industrial and commercial applications. It represents the latest evolution in Elster’s proven rotary meter technology, optimized for both current needs and tomorrow’s challenges.
