ABSTRACT:
In the preferred and illustrated embodiment salinity measuring apparatus is disclosed. An elongate sonde has a housing with an internal chamber. The chamber is perforated by opening to the exterior to introduce well fluid. Transverse plates define the chamber and mount the acoustic transducer which sends an acoustic pulse along the chamber. An acoustic transceiver is coupled to a timer circuit which determines changes in transit time as a function of salinity compared to pure water.
