When the meter is energised, the drive coil vibrates the measuring tubes causing them to
oscillate and produce a sine wave (3). The sine wave is monitored by the two sensors.
When a fluid or gas passes through the tubes, the Coriolis effect causes a phase shift in the sine
wave that is detected by the two sensors. This phase shift is directly proportional to the mass
flow.
Temperature measurement is made using a Pt500 sensor.
