0.2% ACCURACY CALIBRATION TEST BENCH FOR CORIOLIS MASS FLOW METER

NOT A BENCH. A REFERENCE REALITY FOR MEASUREMENT.

Calibration is often described as a procedure.

But for Coriolis mass flow meters, calibration is closer to a question:

Can the instrument still tell the truth when everything around it is already known?

The 0.2% Accuracy Calibration Test Bench is built to answer that question under controlled, repeatable, and traceable conditions.

It is not designed to “check meters”.

It is designed to define what correct measurement should look like in the first place.

THE CORE IDEA: REMOVE UNCERTAINTY FROM UNCERTAINTY

In flow calibration, errors usually come from three layers:

• instability in reference flow
• temperature and density variation
• system pressure fluctuation

This test bench is structured to suppress those variables instead of compensating for them.

So the calibration does not depend on correction.

It depends on environmental control.

ARCHITECTURE OF THE SYSTEM (NOT A SINGLE DEVICE)

The calibration bench is a coordinated system consisting of:

• Master reference flow standard
• High-stability circulation loop
• Precision weighing or gravimetric subsystem
• Temperature and pressure conditioning module
• Data acquisition and comparison engine

Each part does not work independently.

They work as a closed verification loop where:
reference → measurement → deviation → confirmation

WHY 0.2% IS NOT JUST A NUMBER

0.2% accuracy is not a marketing label.

It represents a boundary condition where:

• system error becomes measurable rather than assumed
• repeatability becomes more important than single-point precision
• long-term drift becomes visible in data trend rather than instant output

At this level, calibration is no longer about “adjusting instruments”.

It becomes about validating physical consistency across systems.
