CORIOLIS MASS FLOW METERS SENSORS PRODUCTION

WHERE MEASUREMENT ACCURACY STARTS BEFORE THE PRODUCT EXISTS

A Coriolis mass flow meter does not become accurate at calibration.

It becomes accurate at the moment its sensing element is born.

The sensor production stage is therefore not a manufacturing line in the traditional sense.

It is a precision-controlled formation process of a mechanical measurement system.

Every step determines how well the final device will interpret mass flow, density, and vibration phase shift.

THE CORE COMPONENT: SENSOR TUBE IS THE HEART OF THE SYSTEM

At the center of production is the measuring tube.

This is not a simple metal part.

It is a dynamic oscillation structure that must:

• vibrate at a stable natural frequency
• maintain symmetrical mechanical balance
• preserve elastic consistency across full length
• avoid micro-deformation during forming and welding

Any deviation here will later appear as signal noise or zero drift.

So the tube is treated not as a component, but as a mechanical resonance element.

MATERIAL CONTROL: CONSISTENCY BEFORE SHAPE

Before shaping begins, material selection and control are critical.

The production focus includes:

• alloy uniformity verification
• batch consistency control
• internal stress elimination
• microstructure stability under vibration

The goal is simple:

ensure every tube behaves like the same physical object under identical excitation.

Without this condition, no later calibration can guarantee stability.
