Technical data
6.1 Measuring principle (single tube)
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.
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.
