4.2.2.3 Installation in a drop line
Installation in a drop line is only recommended if a pipeline reduction or orifice with a smaller
cross-section can be installed to create back-pressure and prevent the sensor from being
partially drained while measuring.
① Back pressure orifice
② On / off valve

4.2.2.4 Mounting the sensor
● Install the sensor in well-supported pipelines in order to support the weight of the flowmeter.
● Center the connecting pipelines axially in order to assure a stress-free installation. The
flowmeter must not be used to bring the rest of the pipework into line. Make sure the
pipework is aligned correctly before inserting the flow sensor.
● Install two supports or hangers symmetrically and stress-free on the pipeline closely to the
process connections.
Note
Handling
Lift the flowmeter by the sensor body. Do not lift the flowmeter by the housing.
