OVERVIEW

What it does and why it is built this way

The FL-310 measures mass flow directly, independent of density, viscosity or temperature. Two vibrating tubes twist in proportion to the mass moving through them.

With a custody-transfer accuracy class (demo), Modbus and Profibus PA, it suits fiscal metering, batching and dosing where every kilogram counts.

HOW IT MEASURES

Measuring principle, animated

Drag the slider to see how the measured variable becomes a 4–20 mA signal.

Coriolis mass flow
FL-310 Coriolis Mass Flowmeter | INSTRAVAINLET SENSOROUTLET SENSOR · Δφ ∝ MASS FLOW
MASS FLOW
35,000 kg/h
OUTPUT

  1. Two tubes vibrate at their natural frequency.
  2. Mass flowing through the tubes twists them (the Coriolis force).
  3. Sensors measure the phase shift between inlet and outlet, which is proportional to mass flow.
