The GRP building houses the Tide Gauge equipment which consists of a POL data logger monitoring both pneumatic bubbler systems, and an Ott pneumatic chart recorder. The pressure points are mounted on steelwork which is attached to the pier wall.

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