A fresh water generator is designed to produce fresh water from sea water. This generator produces fresh water by evaporating and condensing sea water, and it uses the engine jacket water as the heat source. While a vessel is sailing, it uses main engine coolant to produce fresh water and also, while a vessel is in port, it uses auxiliary engine coolant. After all, sea water is evaporated the heat which the coolant contains, so it can produce fresh water economically, because it dose not need additional heat source. A salinity meter is a densitometer measuring the concentration of salt in sea water. This study designed the multi-function salinity meter(SAL-2000). SAL-2000 has many functions such as conductivity, salinity, flow rate, and so on. In order to evaluate the performance of SAL-2000, the measuring experiments such as salinity, flow rate, and pressure have been conducted.
