The SSEA Compact Coriolis Mass Flow Meter A-Series

The SSEA triangle shape A-Series Coriolis Massflow Meter measures mass flow, density and temperature of a fluid:

• Liquids and gases, slurries
• Accuracy up to 0.05% for custody transfer and critical process control
• Compact – light weight – long term stability
• Low interference (high frequency to avoid pipe vibration disturbance)
• High pressure (opt. up to 250 bar)
• cryogenic, hygienic, anti corrosion, self-draining
• Up to 5 outputs

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.
