Apparatus comprising a liquid flow path having two parallel connected sections, namely a first section adapted to provide turbulent flow and a second section adapted to provide laminar flow. Water flowing through the apparatus divides between the two sections in a ratio which is arranged to be independent of the total flow, the flow through the second section being saturated with oxygen. The apparatus thus provides a controlled concentration of oxygen. Temperature compensation is achieved by arranging for changes in the flow ratio caused by viscosity var...
Apparatus for providing a controlled concentration of a soluble gas in a flow of liquid, comprising a liquid flow path having first and second parallel connected sections, means for forming a saturated solution of the gas in the liquid flowing along the second section, and means for ensuring that the fraction of the total flow which passes along the second section is substantially independent of the magnitude of the total flow, the concentration of the gas in the liquid flow thereby being controlled at a location downstream in the flow path from the firs...
