20 metre range level probe with an SDI-12 protocol serial digital interface for submerging near to the shore to monitor tidal changes.
The S12C is a submersible level probe with a SDI-12 protocol signal interface and has the option to measure absolute pressure rather than venting to air pressure above the water surface.
The most popular device is the S12S submersible level transmitter with SDi-12 output, this can be supplied with various measurement ranges and cable lengths to suit the installation. There is also the S12C which is a ceramic based sensor with a Marine Bronze housing which is suitable for permanent submersion in estuary and seawater installations. […]
