Tide gauge location

The tide gauge equipment is housed in a GRP building and consists of a pneumatic bubbler system with a single full-tide pressure point mounted on steelwork attached to the stilling well. The Munro float gauge is mounted above the stilling well inside the building. The potentiometer output from the Munro and the pneumatic pressure line are monitored by the POL data logger.

The tide gauge is levelled to the tide gauge bench mark supported by Ordnance Survey auxiliary marks.
