Tide gauge location
The tide gauge equipment is housed in a GRP building and consists of a pneumatic bubbler system with two full tide and mid-tide
pressure points mounted on steelwork attached to the stilling well which once supported a Munro float gauge before the installation
of a two bubbler.
All three pressure lines are monitored by the POL data logger.
There are currently no external users.
