The Alpha series operates on the Coriolis effect principle, providing direct measurement of mass flow, density, and temperature without compensation for fluid properties. It is ideal for high-pressure, cryogenic, and challenging media (liquids, gases, slurries), and is widely used in custody transfer and process control for industries like chemicals, pharmaceuticals, and power generation. The modular transmitter offers flexible output options.
Mass flow measurement: Coriolis forces from fluid flow cause a phase shift in vibrating tubes, with the time difference proportional to mass flow.
Density measurement: Calculated from changes in tube resonance frequency.
Temperature measurement: Integrated sensor provides real-time compensation and output.
High precision: Mass flow accuracy up to ±0.10%, repeatability ±0.05%.
Wide turndown ratio: Up to 50:1 for low-flow applications.
Extreme condition resistance: Maximum pressure 25MPa, temperature range -196℃ to +300℃.Explosion-proof certification:
ATEX and IEC Ex approved (Ex db[ib] IIC T6...T1 Gb).Integrated design: Explosion-proof and anti-corrosion sensor with modular transmitter for remote mounting.

During installation, ensure the sensor arrow aligns with flow direction. For slurries, "flagpole installation" (bottom-to-top flow) is recommended. Sensor sizes range from DN03 to DN200, with sample dimensions below:
25TA sensor dimensions for DN25 pipe
40TA sensor dimensions for DN40 pipe
Wiring requirement: Use dedicated 9-wire shielded cable, max length 100m. Terminals include left/right pickoffs, drive coil, and temperature sensor.
