Coriolis Meters

Accurate, High-Fidelity Flow Measurement with Coriolis Meters

Coriolis meters are a gold standard in gas and liquid flow measurement, providing direct mass flow measurement, density, and temperature data in a single device. Circle B Measurement & Fabrication delivers Coriolis meter solutions engineered for precision, reliability, and long-term operational performance.

Unlike differential pressure or ultrasonic meters, Coriolis meters measure mass flow directly using the Coriolis effect, making them ideal for custody transfer, process monitoring, and energy content verification. By combining advanced meter technology with expert fabrication and integration, Circle B ensures every Coriolis meter delivers accurate, defensible measurement across a range of applications.
