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.
Density measurement is made by evaluation of the frequency of vibration and temperature
measurement is made using a Pt500 sensor.
