The gauge is an Aanderaa WLR7 tide recorder. The gauge is installed along the wharf of Port-aux-France.  This bottom pressure sensor is at the base of a stilling well which is used to filter waves.  The recorder is triggered by a central unit where the barometric pressure is measured at the same time.
