Measures during malfunctions:
In case of malfunctions in the inflow section due to vortexing (e.g. after pipe elbows, at tan-
gential inclusions or with a half-open gate before the sensor), measures for normalization of
the flow profile are necessary.
The appropriate steps are:
•
increasing the inflow and outflow zones
•
using flow conditioners
•
reducing the inner diameter of the pipe

Mounting
As a compact device, the VMM is installed directly i
nto the pipeline. With the separate design,
the sensor is installed in the pipeline. The display electronics can be attached to the wall with
the bracket.
IMPORTANT NOTICES:
•
Only use suitable gaskets for installation.
•
Observe the flow direction indicated on the type plate and
on the back site of the sensor.
•
Observe the mounting dimensions (
Select an appropriate location for installation
(
§ 4.3 "Sensor 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 VMM together with the gaskets.
Connect the flange connections corresponding to the re-
quirements of their use.
WARNING! Risk of injury or material damage!
Incorrect gaskets and connection materials plus improper assembly can lead to injuries
or material damage.
During installation, comply with the requirements that result from your application.
Maintain the required tightening torques.
IMPORTANT!
We
ather protection required
