Installation in the pipe
Type 8098
4 x 90°
→
Turn the transmitter to the desired position.
8.
Make sure the cable stays inside the
transmitter.
20°
→
Turn the transmitter by about 20 degrees
counterclockwise.
→
Place the transmitter on the flow sensor.
→
Screw the transmitter clockwise on the flow
sensor until the transmitter is parallel or perpen-
dicular to the axis of the pipeline.

Recommendations for the installation into the pipeline
→
Protect this device against electromagnetic interference, ultraviolet rays and, when installed outdoors,
the effects of climatic conditions.
→
Make sure the DN of the measurement tube is suited to the flow velocity: refer to the data sheet of the
.
→
Choose a location with enough free space to put the magnetic key against the symbol the on the device.
→
For heavy devices or long pipelines, support the device and pipelines.
→
If the temperature of the liquid is subject to fluctuations, ensure that the device can expand.
→
Install the device upstream a valve or any equipment that changes the diameter or the direction of the
pipeline.
Under reference conditions i.e. measuring fluid = water free from gas bubbles and solids, ambient and water
temperature = 23 °C ±1 °C (73.4 °F ±1.8 F), and short refresh time, while maintaining turbulent or laminar flow
profile, with the minimum inlet (40 x DN) and outlet (1 x DN) distances and the appropriate internal diameter
of the pipes. Deviation from reference conditions can be adjusted through the use of a built-in correction K
factor adjustment or Teach-in procedure.
→
Install the device into either horizontal, oblique or vertical pipelines. But an installation in a vertical
pipeline will be better to prevent air or gas bubbles inside the measurement area.
