Correct use, general safety instructions
1.1 Range of applications, proper use
Sensyflow iG has been designed for mass flow measurement of gases and gas conglomerates in closed
pipe circuits. These operating instructions describe the device version with PROFIBUS DPV1 interface
according to PA profile 3.0.
For proper use it is required to observe the Technical data section in the data sheets. You will find the
data sheets in
see section 10 "Type overview, technical data" on page 53
of these operating instructions.
Any other use is considered improper.

1.2 General safety instructions
1.2.1
Safe operation
The technology of the mass flow meter is state of the art.
It is constructed and tested according to DIN VDE 0411 Part 1 "Safety Requirements for Electronic Mea-
surement Apparatus" and has left the factory in a safe condition. To maintain this state and guarantee
hazard-free operation, all safety instructions in this manual headed by "Caution" must be observed.
Otherwise, personnel might be endangered and the mass flow meter itself or other devices and equip-
ment could be damaged.
Prerequisites for
safe operation
These operating instructions contain important information about the safe and proper operation of the
equipment. Observing these instructions is mandatory for safe operation.
Failure to observe the instructions can cause hazards for life and limb of the user respectively property
damages at the devices or the entire system.
Proper and safe operation of the mass flow meter requires proper transportation and storage, installation
and commissioning by qualified personnel, operation within its design limits, and careful maintenance ob-
serving all information in these operating instructions.
Qualification of per-
sonnel
Only personnel familiar with the installation, commissioning, and maintenance of similar devices and ha-
ving the required qualifications for their tasks are allowed to work on the device.
Operator
The operator of the plant is fully and solely responsible for proper and workmanlike and, thus, safe ope-
ration.
The operator must make sure that the operating instructions have been understood by the target audi-
ence.
