1.4 Measuring principle (single tube)
Static meter not energised and with no flow
1 Measuring tube
2 Drive coil
3 Sensor 1
4 Sensor 2
OPTIMASS 7400
A Coriolis single tube mass flowmeter consists of a single measuring tube 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 tube causing it to oscillate
and produce a sine wave 3. The sine wave is monitored by the two sensors.

OPTIMASS 7400
Energised meter with process flow
1 Process flow
2 Sine wave
3 Phase shift
When a fluid or gas passes through the tube, 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.
