OPTIMASS 3400
1.1 The solution for low flow measurement
The OPTIMASS 3400 is the cost effective solution for accurate measurement in a variety of
applications, where there is a low process flow.
Combined with the power of the MFC 400, the OPTIMASS 3400 will provide accurate
measurement of mass, volume, density and concentration.

A Coriolis single Z tube mass flowmeter consists of a single Z shaped measuring tube (1) two
drive coils (2) and two sensors (3 and 4) that are positioned either side of the drive coils.

OPTIMASS 3400
Energised meter
1 Measuring tube
2 Direction of oscilation
3 Sine wave
When the meter is energised, the drive coils vibrate the measuring tube causing it to oscillate
and produce a sine wave (3). The sine wave is monitored by the two sensors.
PRODUCT FEATURES
1
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.
