Installation guide flowIQ® 4200
• Repeat the same procedure on the opposite pipeline flange
• Lift the meter via the two lifting lugs and lower the meter into place
• Pre-tighten the remaining bolts and nuts
• Tighten the bolts in the described criss-cross pattern and with the correct tightening
torque mentioned in the table
• Repeat the sequence three times to ensure that all bolts are tightened with the correct
torque
4.4 Installation angle
For flowIQ® 4200, it applies that the meter can be mounted at all angles and in all
positions.
However, it is recommended to mount the display in such a way that it is easy to read.
4.5 Straight inlet
Normally, the meter requires neither straight inlet nor straight outlet to achieve accurate
measurement. However, for installation environments with heavy flow disruptions,
several lengths of straight inlets are advisable. This applies to all flange meters.
4.6 Flow disturbance and flow cavitation
The components mentioned below can generate heavy flow disruptions or pressure drops:
• Butterfly valve
• Pressure- and flow-regulated components
• Partially closed ball valve
• Pumps in front of the meter
• Pumps after the meter
• Double conjugation in several directions
4.6.1 Service connection
When the meter has been mounted in the system, neither welding nor freezing is
allowed. The meter must be dismounted from the system before starting such work.
If the electrical service in the building has been grounded via the plumbing, it must be
ensured that adequate electrical ground is maintained both during and after installation.
In order to facilitate replacement of the meter, closing valves should be mounted on
both sides of the meter. Under normal operating conditions, a strainer is not required in
front of the meter.
Note!
To enlarge the gasket gap, utilize the pushing nut milling with a bolt and a nut.
Note!
Cavitation affects the measurement accuracy and may physically damage the meter.
