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.

Page 7
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.

Notes
• The maximum operating pressure will be either the flange rating or the measuring tube
rating, WHICHEVER IS THE LOWER!
• The manufacturer recommends that the seals are replaced at regular intervals. This will
maintain the hygienic integrity of the connection.

3.1 Intended use
This mass flowmeter is designed for the direct measurement of mass flow rate, product density
and product temperature. Indirectly, it also enables the measurement of parameters like total
mass, concentration of dissolved substances and the volume flow. For use in hazardous areas,
special codes and regulations are also applicable and these are specified in a separate
documentation.
Responsibility for the use of the measuring devices with regard to suitability, intended use and
corrosion resistance of the used materials against the measured fluid lies solely with the
operator.
This device is a Group 1, Class A device as specified within CISPR11:2009. It is intended for use in
industrial environment. There may be potential difficulties in ensuring electromagnetic
compatibility in other environments, due to conducted as well as radiated disturbances.
The manufacturer is not liable for any damage resulting from improper use or use for other than
the intended purpose.
INSTALLATION

3.2 Mounting restrictions
3.2.1 General installation principles
There are no special installation requirements but you should note the following
points:
• Support the weight of the meter.
• The meter can be supported on the sensor body.
• On larger meter sizes and hygienic connections, it is strongly recommended that the meter is
not supported solely by the process pipework.
• No straight runs are required.
• The use of reducers and other fittings at flanges, including flexible hoses, is allowed but you
should take care to avoid cavitation.
• Avoid extreme pipe size reductions.
• Meters are not affected by crosstalk and can be mounted in series or in parallel.
• Avoid mounting the meter at the highest point in the pipeline where air / gas can collect.

INSTALLATION
Mounting positions
OPTIMASS 7400
32
1 The meter can be mounted at an angle but it is recommended that the flow is uphill.
2 Avoid mounting the meter with the flow running downhill because it can cause siphoning. If the meter has to be mount-
ed with the flow running downhill, install an orifice plate or control valve downstream of the meter to maintain backpressure.
3 Horizontal mounting with flow running left to right.
4 Avoid mounting meter with long vertical runs after the meter as it can cause cavitation. Where the installation includes
a vertical run after the meter, install an orifice plate or control valve downstream to maintain backpressure.
5 The meter can be mounted vertically but it is recommended that the flow is uphill.
6 Avoid mounting the meter vertically with the flow running downhill. This can cause siphoning. If the meter has to be
installed this way, install an orifice plate or control valve downstream to maintain backpressure.

Zero calibration
INSTALLATION
3
1 Where the meter has been installed vertically, install shut-off valves either side of the meter to assist with zero cali-
bration.
2 If the process flow cannot be stopped, install a bypass section for zero calibration.
3.2.2 Sunshades
The meter MUST be protected from strong sunlight.
