Product introduction

The AC Series Micro-bend Coriolis Mass Flowmeter operates based on the Coriolis effect, wherein fluid flowing through an oscillating bent tube induces measurable deflection due to inertial forces. The micro-bend configuration enhances sensitivity while reducing pressure loss and footprint. As fluid enters the measuring tube, the flow-induced Coriolis force causes a phase shift between inlet and outlet sensors. This phase difference is directly proportional to the mass flow rate. Simultaneously, the fluid's density is derived from the oscillation frequency, and temperature is monitored via integrated RTD sensors.

Physical Properties

★ High-Precision Mass Flow Measurement
Provides direct mass flow measurement with accuracies up to ±0.1% of reading (liquid applications), independent of temperature, pressure, viscosity, or flow profile.

★ Multivariable Measurement Capability
Simultaneously delivers mass flow, density, and temperature readings—ideal for custody transfer, real-time process monitoring, control, and product quality assurance.

★ High Fluid Compatibility
Performs reliably with a wide range of fluids, including high-viscosity, non-Newtonian, slurry, and light gas-liquid multiphase mixtures.

★ Compact and Low Pressure Loss Design
The micro-bend tube geometry offers a compact footprint and significantly lower pressure drop than traditional dual-loop Coriolis designs—suitable for skid mounting or mobile installations.

★ Robust and Corrosion-Resistant Construction
Available in 316L stainless steel, Hastelloy C, or other special alloys, offering resistance to aggressive chemicals, high-pressure fluids, and CIP/SIP environments.

A Coriolis Mass Flowmeter Industry knowledge

The Coriolis mass flowmeter is a High-precision instrument based on the Coriolis force principle and mechanical vibration. It directly measures the mass flow rate, density, and temperature of a fluid.
Inside the sensor, a measuring tube vibrates due to a driving force, generating sinusoidal signals. When fluid flows through the tube, the Coriolis force causes a deformation, creating a phase shift between the tube's ends. The larger the mass flow, the greater the phase shift. The transmitter detects and calculates this phase difference to determine the mass flow rate.
The measuring tube vibrates at its resonant frequency, which shifts with changes in fluid density. The transmitter calculates the fluid's density by detecting this frequency change.
The sensor also includes a precise temperature measurement component, which monitors the tube's temperature and can be used to compensate for temperature effects on mass flow and density measurements.
