Tide gauge location

The tide gauge equipment is housed in a brick building which also contains a Munro gauge mounted over a stilling well. The gauge is no longer used and the stilling well has been filled in. The present equipment consists of a pneumatic bubbler system with two full tide and mid-tide pressure points mounted on steelwork attached to a pile under the quay to the left of the lamp post seen in the centre of the photograph. All three pressure lines are monitored by the POL data logger.
