Safety instructions

7

The measuring device described in these Operating Instructions is to be used only for measuring the 
mass flow rate of liquids and gases. At the same time, the system also measures fluid density and 
fluid temperature. These parameters are then used to calculate other variables such as volume flow. 
Fluids with widely differing properties can be measured.

Examples:
• Chocolate, condensed milk, liquid sugar
• Oils, fats
• Acids, alkalis, lacquers, paints, solvents and cleaning agents
• Pharmaceuticals, catalysts, inhibitors, suspensions
• Gases, liquefied gases, etc.

Resulting from incorrect use or from use other than that designated the operational safety of the 
measuring devices can be suspended. The manufacturer accepts no liability for damages being 
produced from this.

Note the following points:
• Installation, connection to the electricity supply, commissioning and maintenance of the device 

must be carried out by trained, qualified specialists authorized to perform such work by the 
facility's owner-operator. The specialist must have read and understood these Operating 
Instructions and must follow the instructions they contain.

• The device must be operated by persons authorized and trained by the facility's owner-operator. 

Strict compliance with the instructions in the Operating Instructions is mandatory.

• FMC Technologies is willing to assist in clarifying the chemical resistance properties of parts 

wetted by special fluids, including fluids used for cleaning. However small changes in 
temperature, concentration or the degree of contamination in the process can result in changes 
of the chemical resistance properties. Therefore, FMC Technologies can not guarantee or accept 
liability for the chemical resistance properties of the fluid wetted materials in a specific application. 
The user is responsible for the choice of fluid wetted materials in regards to their in-process 
resistance to corrosion.

• If carrying out welding work on the piping, the welding unit may not be grounded by means of 

the measuring device.

• The installer must ensure that the measuring system is correctly wired in accordance with the 

wiring diagrams. The transmitter must be grounded, except in cases where
special protective measures have been taken (e.g. galvanically isolated power supply SELV
or PELV).

• Invariably, local regulations governing the opening and repair of electrical devices apply.

Note the following points:
• Measuring systems for use in hazardous environments are accompanied by separate 

"Ex documentation", which is an integral part of these Operating Instructions. Strict compliance 
with the installation instructions and ratings as stated in this supplementary documentation is 
mandatory. 
The symbol on the front of this supplementary Ex documentation indicates the approval and the 
certification body (e.g. 

0 Europe, 2 USA, 1 Canada).

• The measuring device complies with the general safety requirements in accordance with 

EN 61010-1, the EMC requirements of IEC/EN 61326, and NAMUR recommendation NE 21, 
NE 43 and NE 53.
