- Series VMI
•
Installation can occur in horizontal and vertical pipes. The flow sensor is only suitable for
application in completely filled pipe systems.
•
As a matter of principle magnetic inductive flow sensors are widely independent from the
flow profile. An inlet section is not absolutely necessary.
To reach a most highly accuracy of the measurement, you should use straight inlet and
outlet sections according to the nominal width (DN). The inlet section has to be at least
10 x DN; the outlet section 5 x DN in order to achieve the specified accuracy.
•
The inlet and outlet sections and the gaskets must have the same or a slightly larger in-
side diameter than the measuring tube in order to achieve the specified accuracy.
4.2 Mounting
The VMI is installed directly into the pipeline. The compact design and light weight of the unit
make wall-mounting unnecessary.
IMPORTANT NOTICES:
• Only use suitable gaskets for installation.
• Observe the flow direction indicated on the type plate.
• Observe the mounting dimensions ( § 9.5 "Dimensions").
Select an appropriate location for installation ( § 4.1
"Installation instructions").
To ensure the best possible measuring accuracy, a vertical
installation position with increasing flow is preferable (no col-
lecting of dirt deposits).
Install the appropriate screwed connections at the installa-
tion location.
Insert the VMI together with the gaskets.
Screw the union nuts of the screwed connection onto the pro-
cess connections of the VMI.
CAUTION! Material damage!
Pay attention to maximum torque.
While tightening, counter the union nut on the hexagon of the
process connection!
If you do not counter it, the VMI can be damaged!
VMI 07 - G½
15 Nm
Tighten both union nuts.
When tightening, use a spanner (AF 27 or AF 34) to counter
the process connection on the hexagon in place.
