5 Installation
Safety instructions
WARNING
Risk of injury due to live parts.
Improper work on the electrical connections can result in
electric shock.
•
Connect the device only with the power supply switched
off.
•
Observe the applicable standards and regulations for the
electrical connection.
WARNING
Risk of injury due to process conditions.
The process conditions, for example high pressures and
temperatures, toxic and aggressive measuring media, can
give rise to hazards when working on the device.
•
Before working on the device, make sure that the process
conditions do not pose any hazards.
•
If necessary, wear suited personal protective equipment
when working on the device.
•
Depressurize and empty the device / piping, allow to cool
and purge if necessary.
Installation conditions
Mounting position
Any mounting position can be selected.
Inlet sections
To prevent negative effects on measuring accuracy, the ISO-
KF flange DN 25, Transair, G ³⁄₄ in and G 1 should be provided
in the inlet sections when using the connections.
Straight undisturbed pipe sections must be provided as inlet
sections; they should have a length of approx. 10 × D on the
inlet side.
These inlet sections make sure that any disturbances of the
flow profile are eliminated before reaching the actual
measuring point at the sensor.
If maintaining the required inlet sections is not possible, a
flow conditioner can be retrofitted. However, the flow
conditioner causes a significantly increased pressure drop.
When using the G ½ in and G ⅜ in adapters, no additional
inlet sections are required, as flow straightener components
are implemented on the inlet side of the adapters. Note that
flow conditioners cause considerable pressure drop.
Installation of setting equipment
Components affecting the flow, e.g. valves or shut-off valves
should be installed on the outlet side, therefore downstream
of the measuring point.
