Introduction

The FCC800 Coriolis Mass Flow Meter measures the mass flow rate of liquids and gases directly by detecting the Coriolis force induced by fluid movement inside vibrating U-shaped tubes.

In addition to mass flow, the FCC800 Coriolis effect mass flow meter also reports fluid density, fluid temperature, and volumetric flow derived from mass data. Key performance parameters such as excellent linearity, fast response, and strong anti-vibration capability make it ideal for marine instrumentation systems.

Designed to support ISO and marine regulatory requirements, the FCC800 Coriolis principle flow measurement enhances operational control, fuel management accuracy, and safety in marine process systems.

Working principle

The FCC800 flow meter based on Coriolis principle employs Coriolis mass flow technology, which operates through three key mechanisms:

1. Vibration Excitation

The Coriolis effect flow meter’s sensor tubes are mechanically excited to vibrate at a consistent frequency. This vibration serves as the baseline for detecting fluid-induced changes.

2. Fluid Movement & Coriolis Force

As fluid moves through the vibrating tubes, Coriolis forces develop. These forces cause slight twists in the tube motion proportional to the mass flow rate. The greater the mass flow, the more pronounced the tube deformation.

3. Signal Detection & Calculation

Strain sensors on the tubes detect the deformation caused by Coriolis forces. These signals are processed by the meter’s electronics to calculate mass flow, density, and temperature. Output values can be integrated into control systems through analog, digital, or fieldbus protocols.
