2.1 Measuring principle (twin tube) Static meter not energised and with no flow Measuring tubes Drive coil Sensor 1 Sensor 2 A Coriolis twin tube mass flowmeter consists of two measuring tubes ① a drive coil ② and two sensors ( ③ and ④ ) that are positioned either side of the drive coil. Energised meter 1 Measuring tubes 2 Direction of oscillation 3 Sine wave 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.

Energised meter with process flow 1 Process flow 2 Sine wave 3 Phase shift 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.
