In large DN80 (3-inch) pipelines where space is at a premium but measurement integrity is non-negotiable, the Micro Motion G300M is the ultimate solution. This 316L Stainless Steel Coriolis meter bridges the gap between massive industrial sensors and compact skid-mounted designs. Weighing only 35 kg (77 lb), it delivers elite measurement reliability for bulk liquids and gases in both standard industrial and high-purity sanitary environments.
The G300M is engineered to solve the "dead space" challenge. It offers superior self-draining capability in both vertical and horizontal orientations. This is a critical requirement for CIP (Clean-in-Place) and SIP (Steam-in-Place) processes, ensuring that no product or cleaning fluid remains trapped in the sensor. For 3-inch high-flow lines, this means faster product changeovers and zero risk of batch cross-contamination.
While industrial 3-inch meters are typically bulky, the G300M features an ultracompact footprint (approx. 58.3 cm length) that fits easily into tight piping layouts and mobile platforms. Despite its size, it provides elite ±0.10% mass flow accuracy. Combined with Smart Meter Verification (SMV), you can perform a complete health check on the sensor in under 90 seconds without interrupting the flow, ensuring long-term fiscal-grade performance.

Modern 3-inch pipelines require more than just flow data. The G300M provides real-time density and temperature measurement, allowing for immediate concentration analysis and quality control. Its robust 316L Stainless Steel construction and laser-etched tagging ensure it survives harsh chemical washdowns and outdoor environments. Whether you are managing bulk chemical distribution or large-scale beverage blending, the G300M reduces installation costs while maximizing measurement confidence.
Q: Can the G300M be used for custody transfer?
A: Yes, when configured with the ±0.10% accuracy option and paired with high-end Micro Motion electronics, the G300M meets the rigorous repeatability and accuracy standards required for bulk custody transfer.
Q: How does the "Self-Draining" feature benefit my process?
A: Self-drainage ensures that no fluid stays in the sensor tubes when the line is emptied. This is vital for food and pharma industries to prevent bacterial growth and for chemical plants to prevent corrosion or product hardening.
Q: Is it difficult to install due to its weight?
A: At only 35 kg (77 lb), the G300M is significantly lighter than standard 3-inch Coriolis meters, making it easy to handle with standard lifting equipment and suitable for mobile truck-mounted systems.
