3.4.2 Mounting the meter
Mounting positions
OPTIMASS 8000K
16
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.

OPTIMASS 8000K
3.4.3 Gas / liquid build up
In certain applications, the design of the meter can cause either gas or liquid to build up in the
measuring tube.
1 Where liquids are being measured, mount the meter as shown. This will prevent gas building up in the measuring tube,
when there is no flow.
2 Where gases are being measured, mount the meter as shown. This will prevent liquids building up in the measuring
tube, when there is no flow.
INSTALLATION 3
3.4.4 Side mounting
The meter can be installed with the converter (or remote junction box) on the side of the meter
so that the measuring tubes are sitting one above the other. Avoid this method of installation
where there is a two phase process flow, or where the process fluid contains gas. If this situation
cannot be avoided, please contact the manufacturer for advice.

3.4.9 Flexible connections
Flexible connections can be used but because of the high flow rates associated with large
diameter meters, it is recommended that flexible connections are not used on meters larger
than size 80.
3.4.10 Hygienic installations
OPTIMASS 8000K
Mounting the meter for hygienic applications
1 Install the meter vertically to allow self draining.
2 DO NOT install the meter horizontally.
Where the meter has been approved by the sanitary requirements of the European Hygienic
Engineering and Design Group, you MUST give consideration to:
• Installation - install the meter at an angle to allow self-draining (see illustration).
• Cleaning fluids - cleaning fluids should flow uphill with a velocity rate greater than
1.5 m/s / 5ft/s. If the process flow is downhill, install a flow restrictor downstream of the
meter. This will make sure that the meter is completely filled with the cleaning fluid.
• Process connections and seals MUST be in accordance with EHEDG documentation.
20
The manufacturer also recommends that you refer to EHEDG (www.ehedg.org) document
number 8 "HYGIENIC EQUIPMENT DESIGN CRITERIA".

3.4.11 Heating and insulation
Insulation
Insulation
InsulationInsulation
The meter can be insulated to a maximum depth as shown (A). Do not insulate above this depth
as this will cause the electronics to overheat.
If the meter has been ordered with a heating jacket, it will be supplied with DN15 PN40 to DIN
2501 or 1/2¨ ASME150 flange connections.
Connecting / using the heating jacket
• Use rigid or reinforced flexible hoses to connect the heating jacket to the heat source.
• The heating jacket material is 304.
• Suitable heating mediums are steam or hot oil. Avoid the use of heating mediums that can
cause crevice corrosion in Stainless Steel.
www.krohne.com08/2010 - 4000921002 - MA OPTIMASS 8000k R02 en
21
3 INSTALLATION
• Where liquid is being used, set up the pipe configuration so that air can be vented from the
system.
• Where steam is being used, set up the pipe configuration so that condensation can be drained
off.
• Heat the jacket to working temperature before flowing the process fluid through the meter.
CAUTION!
The design of the heating jacket is such that NO end load pressure (negative or positive) can be
applied. The manufacturer recommends that (where possible) flexible hoses are used to connect
to the heat source.
CAUTION!
The maximum heating pressure and temperature for heating jackets is 10 barg at
°
C / 145 psig at 446°F
230
3.4.12 Purge ports
If the meter has been ordered with a purge port, it will be supplied with NPT female connections
which are clearly marked. The connections are sealed with NPT plugs and PTFE tape.
OPTIMASS 8000K
CAUTION!
DO NOT remove these plugs.
The meter is factory sealed with a dry nitrogen gas fill and if moisture is allowed to enter the
meter casing it will cause damage. The plugs should only be removed to purge the meter casing
in the event that the primary measuring tube fails.
If it is suspected that the primary measuring tube has failed, de-pressurise the meter and
remove it from service, as soon as it is safe to do so.
3.4.13 Burst dics
If the meter has been ordered with a burst disc, it will be supplied with the disc fitted. The failure
pressure of the disc is 4 barg at +20°C / 58 psig at +68°F.
CAUTION!
The fitted burst disc will be suitable for the flow rates and process conditions specified on the
original order. If the process conditions alter in any way, it is recommended that you contact the
manufacturer for advice regarding suitability.
If the process product is hazardous (in any way) it is recommended that an exhaust tube is
connected to the NPT male thread of the burst disc and the pipe routed so that the process
product can be discharged to a safe area. Use a tube with a diameter large enough AND routed in
such a way, so that pressure cannot build up in the meter case.

3 Phase shift
When a fluid or gas passes through the tubes, 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.
