6.1 Measuring principle (twin tube)

Static meter not energised and with no flow
1 Measuring tubes
2 Drive coil
3 Sensor 1
4 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 oscilation
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.
