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 the specifically designed vibrating tubes.

In addition to mass flow measurement, the FCC800 Coriolis effect mass flow meter also reports fluid density, fluid temperature, and volumetric flow derived from mass data. Its 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 onthe Coriolis principle, employs Coriolis mass flow technology to operate via the three key mechanisms:

1. Vibration Excitation

The Coriolis effect flow meter’s sensor tubes are mechanically excited to vibrate at a consistent frequency, and 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, which 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, and these signals are processed by the meter’s electronics to calculate mass flow, density, and temperature. After that, the output values are integrated into control systems through analog, digital, or fieldbus protocols for further operations.
