6. Special Options
6.1 Use in hazardous areas
MFM 4085 K/F - Ex Coriolis massflow meters are approved for use in hazardous areas as
electrical equipment in conformance with the harmonised European Standards and Factory
Mutual (FM). Conformity between the temperature classes and the temperature of the process
fluid, meter size and material of the measuring tube is defined in the test certificate. The Test
Certificate, certificate of conformity and wiring instructions are included in the Installation and
Operating instructions for Ex equipment.
This is a separate manual to the standard Installation and Operating manual and is only
supplied when an instrument for use in a hazardous area is ordered. If you have an ”Ex”
instrument, please ensure that you have this manual and read it carefully before using the
massflow meter.
6.2 Converter with non-standard output options
The flowmeter may be supplied with one or more of the output options as mentioned in Part B,
Section 4.7. These are factory fitted options and changes should not be attempted by
unqualified personnel. Most of these options are hi-pot-tested to comply with the requirements
of Ex and CE and if field exchanged these requirements may be violated. * Krohne will also not
accept responsibility or honour the warranty if this is done. If you need an option change,
please contact your nearest office for advice.
*All options are not compatible in certain configurations with older versions of software.
6.3 Concentration measurement
The Corimass G-Series may be fitted with a concentration measurement option. This option
enables the meter to measure sugar concentration in

Brix or
°
Baumé, concentration by mass
or volume.
The fluid may be a liquid / liquid or a liquid / solid suspension mixture. If the meter has been
fitted with this option a separate Concentration manual will be supplied with the meter.
If you have any queries, please contact your local Krohne office for further assistance.
