Why is the dual-bent tube configuration critical for low-flow Coriolis meters?

Unlike unstable single-tube designs that suffer from high zero-point drift, the dual-bent tube architecture of the Rotamass Nano physically balances out external pipe vibration and temperature-induced mechanical stress. This mechanical decoupling results in a vastly superior signal-to-noise ratio necessary for repeatable micro-flow tracking.

Is the Rotamass Nano approved for high-pressure gas applications?

Yes, standard models support process pressures up to 285 bar, with high-pressure specialty configurations rated up to 460 bar (6672 psi), making it fully compliant for hydrogen, chemical injection, and specialized gas dosing.

Description

Yokogawa Rotamass Nano Coriolis Mass Flow Meter

Micro-Flow Mass and Density Tracking via Dual-Bent Tube Architecture

The Yokogawa Rotamass Nano stands as the industry's smallest dual-bent tube Coriolis mass flow meter, explicitly designed to eliminate the measurement instability common in low-flow processing loops. Where traditional single-tube meters fail due to pipe vibration and fluctuating ambient thermal stress, the Rotamass Nano utilizes a balanced dual-tube geometer to achieve robust zero-point stability. For process engineers optimizing complex multi-variable plants with integrated Endress+Hauser field instrumentation networks, the Rotamass Nano provides an ideal specialized micro-flow expansion capable of tracking real-time mass, density, and temperature simultaneously.

Powered by the advanced Total Insight (TI) electronic platform, this transmitter fleet goes beyond raw data. It delivers ongoing inline diagnostics, concentration calculations for mixable/unmixable fluids, and predictive maintenance alerts to prevent unpredicted line shutdowns in critical chemical and pilot plant infrastructure.

❓ Frequently Asked Technical Questions

Q: What makes the dual-tube configuration superior to single-tube designs for low flows?
A: Single-tube meters suffer severely from ambient temperature shifts and pipe stresses, causing the zero point to drift. The Rotamass Nano's dual-bent design creates a closed, balanced internal tuning fork loop that ignores outside plant vibration, locking in high accuracy even at the lowest flow scale boundaries.

Q: Can the Rotamass Nano handle gaseous media or ambient temperature spikes?
A: Yes. The meter is thoroughly calibrated for low-density gas, high-pressure gas, and unmixable liquid-gas mixtures. It handles fluid process process temperatures from -50°C up to +260°C with zero degradation in signal precision.
