Tide gauge location
The tide gauge is located in the pier electrical room with access through the floor for the pneumatic tubes connected to the pressure points below.
The pneumatic bubbler system consists of two full tide and mid-tide pressure points.
All three pressure lines are monitored by the POL data logger. The tide gauge is levelled to the tide gauge bench mark supported by Ordnance Survey auxiliary marks.
