Reliable solutions
The fixed bottom frame mooring is
typically used in fixed deployment
situations i.e. for harbour surveillance
systems.
The bottom mounted frame supports
extended battery capacity in the form
of external battery package or external
power by means of a cable to the shore.
Data may be output in real time as RS-
232, RS-485 or PDC-4 packages.
Due to slow data rate on the PDC-4
output, only a limited set of current
speed cells and other sensor data may
be sent.
The in-line frame may be pre-installed in
the mooring string, allowing the
instrument to be inserted into the frame
just-in-time by means of two hand-
operated screws.
The in-line frame together with the fully
electronic compass and tilt sensor, allow
for upwards as well as downwards looking
deployments.
For long-term deployments a separate
special battery container may be used to
prolong the deployment period.
