2.3 General safety instructions
DANGER
Use of media that are a health hazard may result in caustic burns or
poisoning
▶
When removing the flow meter, avoid touching the medium and breathing gas
residues left in the sensor.
▶
Wear protective clothing and a breathing mask.
WARNING
High medium temperatures may result in hot surfaces and therefore a risk
of burns
▶
Apply thermal insulation to sensor.
▶
Attach warning labels to the sensor.
▶
Wear protective gloves.
WARNING
Risk of injury from electrical shock due to inadequate clothing
▶
Wear protective clothing as required by regulations.
WARNING
Risk of injury from electrical shock at the transmitter
▶
Avoid handling the transmitter with wet hands.
▶
Wear protective gloves.
The following basic safety instructions must be observed when handling the flow meter:
▶
Carefully read the user's manual prior to operating the flow meter.
▶
When using the flow meter in areas at risk of explosion, compliance with the Ex in-
struction manual is mandatory.
▶
Only qualified specialist personnel must be charged with the tasks described in this
user's manual.
▶
Ensure that personnel complies with locally applicable regulations and rules for work-
ing safely.
▶
Do not remove or cover safety markings and nameplates from flow meter.
▶
Replace soiled or damaged safety markings on the flow meter. For replacing please
contact the Yokogawa Service Center.
▶
If Rotamass Total Insight is used to measure safety-related quantities, ensure that the
transmitter does not display any error messages and, if applicable, the total health
check function is performed at regular intervals (see applicable General Specifica-
tions GS01U01B
␣␣
-00
␣␣
-R, chapter "Options").
▶
Avoid erosion and corrosion as they reduce accuracy and resistance to temperature
and pressure. Over time, calibration constants change as a result of erosion and cor-
rosion, therefore requiring recalibration. Rota Yokogawa does not assume any guar-
anty or liability with respect to corrosion resistance of wetted parts in any specific
process. The user is responsible for selecting the appropriate materials. Rota
Yokogawa provides support in clearing up the question of corrosion resistance of the
materials used (special media but also cleaning agents). Minor changes in tempera-
ture, concentration or pollution degree in the process may result in differences in
terms of corrosion resistance. In case of corrosion or erosion, the pipes must be
checked periodically to ensure necessary wall thickness. This can be accomplished
by using, for example, the tube health check function (see applicable General Specifi-
cations GS01U01B
␣␣
-00
␣␣
-R, chapter "Options").
▶
When performing welding tasks on the pipe, it is important not to ground the welding
equipment by way of the flow meter. Soldering and welding work on parts of the flow
meter is prohibited.
