6.1 Installation instructions
WARNING
Risk of injury during installation due to insufficiently trained personnel
▶
Only have skilled personnel install the flow meter.
NOTICE
Risk of damage to the flow meter due to excessive mechanical stress
▶
The flow meter must not be used as a support for climbing (e.g. during installation
work on the tube system). The flow meter must not be used to support external loads
(e.g. as a support for pipes) or as a surface for depositing heavy tools (e.g. during in-
stallation work on the pipe system).
▶
The weight of the flow meter may generate additional mechanical forces on the pip-
ing that might lead to tensions at process connections. Design measures must be
taken to prevent the above.
NOTICE
Risk of damage to the flow meter due to mechanical influences
▶
Protect the flow meter from vibration, shocks and mechanical strain.
NOTICE
Meet the environmental conditions of the respective General Specifications
(see GS01U10B0
␣␣
-00
␣␣
-R) to prevent disturbance of other sensitive electrical equip-
ment due to increased electromagnetic emissions.
6.1.1 Installation dimensions
Dimensions and installation lengths of sensor and transmitter are listed in the General
Specifications of the corresponding Rotamass Total Insight family in the chapter
Mechan-
ical specification
.
6.1.2 Installation site
In order to ensure stability while operating the flow meter, the following rules regarding
placement must be followed:
CAUTION
Risk of injury during installation, if space for free movement is insufficient
▶
Select an installation site that offers enough space for installation, electrical installa-
tion, maintenance, etc.
NOTICE
Risk of damage to the flow meter due to extreme environmental conditions
▶
Do not install flow meter in locations subject to severe temperature fluctuations.
▶
Do not install flow meter in locations subject to direct insolation or install additional
sun protection.
▶
Avoid installation sites susceptible to cavitation, such as immediately behind a control
valve.
▶
Install flow meter far removed from motors, transformers or other transmitters.
▶
If the plan calls for installing two sensors of the same kind back-to-back, use a cus-
tomized design. Contact the responsible Yokogawa sales organization.
▶
Operate the flow meter below an elevation of 2000 m above sea level.
▶
If possible, avoid installing the flow meter at the end of a downpipe.
