Sensor installation instructions
CAUTION! Risk of malfunction due to external magnetic fields!
Magnetic fields close to the device can cause malfunctions and
should be avoided.
Ensure that no external magnetic fields are present at the in-
stallation site of the VMM.
Please observe § 1.1 "Delivery, unpacking and accessories" and the following installation in-
structions:
General:
•
The VMM can always be installed at any point on the pipeline in the horizontal as well as
in vertical sections.
Ideally, the sensor should be installed in a pipeline with a sufficient straight run, both be-
fore and after the measuring point.
•
Basically, the measuring principle does not depend on the flow profile. You should use
straight inlet and outlet sections according to the inner diameter (ID). An inflow path of
5 x ID and an outflow zone of at least 2 to 3 x ID is required.
•
The flow sensor is only suitable for application in completely filled pipe systems.
Wi
th a
free pipe outlet, the sensor should not be installed in pipe sections that could run empty
(e.g., downpipes).
