General Safety Information

Unauthorised access!
Ensure that there can be no unauthorised
access to the device.
Only trained personnel may fit, install, maintain
and operate this sensor.
Functional limitations

bles adhering to it (visual check).
Observe the applicable national guidelines
relating to maintenance, service and calibration
intervals.
Definition
An electrical technician is able to complete work on electrical systems
and recognise and avoid possible dangers independently based on
his/her technical training and experience as well as knowledge of perti‐
nent standards and regulations. An electrical technician must be able to
perform the tasks assigned to him/her independently with the assis‐
tance of drawing documentation, parts lists, terminal and circuit dia‐
grams. The electrical technician must be specifically trained for the
working environment in which the electrical technician is employed and
be conversant with the relevant standards and regulations.
The Service department refers to service technicians, who have
received proven training and have been authorised by ProMinent to
work on the system.
Operational prerequisites
Only use the sensor in bypass fittings that
ensure the correct flow parameters (l/h, see
Technical Data).
Ensure that there is a free flow or at most a
back pressure of 1 bar at the outlet of the
bypass fitting. Note the maximum operating
pressure for the individual components.
Do not disconnect the power supply to the
sensor.
It is necessary to run in and recalibrate the
sensor following longer interruptions to the
power supply (> 2 h).
