OPTIMASS 1 SAFETY INSTRUCTIONS
Congratulations on purchasing this high quality product. To get the best out of your mass
flowmeter, please take some time to read through this handbook which describes the many
features and options available. Please refer to the index for a list of detailed topics.
If applicable, a separate document is supplied that describes hazardous area information.
1.1 Intended Use
The OPTIMASS mass flowmeter family is designed for the direct measurement of mass flow
rate, product density and product temperature. Indirectly, it also enables measurement of
parameters such as: total mass; concentration of dissolved substances and the volume flow.
For use in hazardous areas, special codes and regulations are applicable which are specified in
a separate handbook.
Responsibility as to the suitability and intended use of our instruments rests solely with the
purchaser. The supplier does not accept any liability resulting from misuse by the customer.
Improper installation and operation of the flow meters may lead to loss of warranty. Warranty
is also null and void if the instrument is damaged or interfered with in any way.
In addition, the “general conditions of sale” which forms the basis of the purchase agreement
are applicable.
If you need to return your OPTIMASS flow meters to KROHNE, please complete the form on the
last page of this handbook and return it with the meter to be repaired. KROHNE regrets that it
cannot repair or check your flow meter unless accompanied by a completed form.
1.2 CE/EMC Standards/Approvals
The OPTIMASS family with the MFC 300/010 signal converter meets all the requirements of the
EU-EMC and PED Directives and bears the CE Symbol.
The OPTIMASS system is approved for hazardous duty installations to the harmonised
European Standards (ATEX) to Factory Mutual (FM) and CSA (Canadian Standards).
Technical data subject to change without notice
It should be noted that this handbook MUST be read in conjunction with the following additional
documentation:
• Hazardous Areas Handbook.
• Communications Handbook.
• Concentration Handbook.
• Corrosion Guidelines.
1.3 PED Integrity
To ensure the PED integrity of the meter, you MUST ensure that the serial numbers on both the
conveter (or remote terminal box) data label and the sensor match.
1.4 Secondary Containment & Burst Discs
Where the meter is being used to measure:
• high pressure gases
• gases kept as liquids by high pressure
and/or where there is a risk of tube failure because of:
• the use of corrosive and/or errosive process fluids
• frequent pressure and/or temperature shocking
• seismic or other shock loading
Krohne strongly recommends that a secondary containment option is purchased. Where the
above situation applies and the process pressure exceeds the secondary pressure contain-
ment, Krohne recommends that the burst disc option is also purchased. For more information,
please contact Krohne Ltd
