1.2 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.
CAUTION!
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.

SAFETY INSTRUCTIONS
1.4 Associated documents
This handbook should be read in conjunction with relevant documents in relation to:
• hazardous areas
• communications
• concentration
• corrosion
1.5 Pressure Equipment Directive (PED)
LEGAL NOTICE!
The Pressure Equipment Directive places legal requirements on both the manufacturer and the
end user. Please read this section carefully!
Visual check
OPTIMASS 2000
XXXXX
To ensure the PED integrity of the meter, you MUST check that the serial numbers on the
converter nameplate and the sensor nameplate are the same.
To comply with the requirements of the Pressure Equipment Directive (PED) the manufacturer
provides all the relevant technical data in the technical data section of this handbook. In addition
to which, the following should also be noted:
• Secondary pressure containment is NOT supplied as standard.
• The non PED / CRN approved outer cyclinder has a typical burst pressure greater than
100 barg / 1450 psig at 20°C/68°F.
• The wiring feedthrough is made of Epoxy, PPS or PEEK with two O-rings made from FPM /
FKM & Hydrogenated Nitrile.
• If the measuring tube/s fails, the O-ring and feedthrough will be in contact with the process
product.
• You MUST make sure that the O-ring ring and feedthrough material is suitable for the
application.
• Alternative O-ring materials are available on request.

www.krohne.com 08/2014 - 4000810003- MA OPTIMASS 2000 R03 en
OPTIMASS 2000
Secondary pressure containment
Where the meter is being used to measure high pressure gases and / or gases kept as liquids by
high pressure and / or where there is a risk of tube failure because of the use of corrosive or
erosive fluids, frequent pressure and / or thermal cycling, seismic or other shock loading, a
secondary containment option MUST be purchased
Where the above situation applies and the process pressure exceeds the secondary pressure
containment (please refer to technical data) or where secondary pressure containment is not
available, the burst disc option MUST also be purchased. For more information, please contact
your nearest representative.
DANGER!
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.
1.6 Dirty gas
Dirty gas is gas that carries sand or other solid particles. Dirty gas causes excessive wear to the
primary measuring tube that can eventually result in complete tube failure. In some situations
tube failure where gas is being measured, can be very dangerous.
SAFETY INSTRUCTIONS
1
DANGER!
If the meter is being used to measure gas and there is a risk that the gas might be dirty, you
must fit a filter upstream of the meter to catch solid particles.

2.2 Nameplates
INFORMATION!
Look at the device nameplate to ensure that the device is delivered according to your order.
Check for the correct supply voltage printed on the nameplate.
2.3 CSA Dual Seal
To comply with the requirements of ANSI/ISA -12.27.01-2003 “Requirements for process Sealing
Between electrical systems and Flammable or Combustible process Fluids” a secondary seal is
incorporated into all OPTIMASS / GAS products. If the primary seal fails, the secondary seal will
prevent escaping fluid reaching the electronic compartment.
Pressures and / or temperatures are limited by tube, temperature, connection and Ex limits.
Check the meter nameplates and relevant documentation for full details. On all meters
operating on gas measurement, the casing of the meter is fitted with a burst disc. If the primary
seal (tube) fails leakage will occur from the burst disc. Install the meter so that the burst disc is
pointing away from personnel.

If the primary seal fails, the casing of the meter will fill with liquid and the meter will stop
working. The meter will notify the operator by going into <Startup> mode and a diagnostic error
will be shown on the converter or PLC display. This is an indication that the primary seal (tube)
has failed and the status of the meter should be checked.

The meter will also go into <Startup> mode if the primary seal (tube) fails, or if they are not
completely filled with fluid. For example, if the meter is drained or re/filled.
To check the status of the meter, drain and re/fill with fluid and note the converter or PLC
display. See the relevant section of the converter handbook for a list of status messages and
diagnostics information.
If the meter remains in <Startup> mode you MUST assume that the primary seal (tube) has failed
and the appropriate action MUST be taken.

Pressures and/or temperatures may be further limited by tube, temperature, connection and Ex
limits. Consult the meter nameplate and relevant documentation for full details.
On all meters operating on gas measurement the casing of the meter is fitted with a burst disc. If
the primary seal (tube/s) fails leakage will occur from the burst disc. Install the meter so that the
burst disc is pointing away from personnel.

DEVICE DESCRIPTION
Regular maintenance of the burst disc:
Regular maintenance of the burst disc:
Regular maintenance of the burst disc:Regular maintenance of the burst disc:
Carry out regular maintenance checks on burst discs for leakage and/or blockages. On all
OPTIMASS meters, the primary seal is considered to be the measuring tube of the meter. The
materials of construction of the measuring tube/s are described within the relevant sections of
this handbook and the customer’s product and any other fluid flowing through the tube must be
compatible with the material of construction. If failure of the primary seal is suspected then the
process line should be de-pressurised and the meter removed as soon as it is safe to do so.
Please contact customer service for servicing or replacement of the meter.
