Abstract: Method and installation for the treatment of liquids, especially oxygen enrichment of water is used for aqua culture purposes such as the breeding of fish. Thus, it is an object to provide a method where gas bubbles in the water reservoir are avoided and where one freely can treat fresh water and/or recirculated water for optimal temperature control and/or water renewal. The water flow is mixed with a flow of pure oxygen gas which is supplied from an oxygen tank 4 with liquid oxygen. The oxygen is led through an evaporator 16 into a flow system which forms a recirculating circuit, with pipeline, and oxygen enrichment means or reactor unit 2 where water and oxygen are mixed to form a turbulent, foaming gas/liquid flow. The mixture is subsequently led into a gas/liquid separator 3 where gas and liqid are separated. The gas mixture from the separator which now in addition to oxygen also will contain other contaminants like nitrogen and carbon dioxide, is recirculated by means of a compressor 6. To prevent the building up of great amounts of nitrogen and other contaminants, there is provided a de-aeration means in the form of a bleed 10 or in the form of a special separation unit.

Abstract: A transmitter that provides an output indicating pressure difference between a line pressure and atmosphere outside the transmitter is made intrinsically safe by coupling the sensor cavity as well as other cavities where ignition can occur to atmosphere only through flame quenching paths. The opening in the transmitter housing in which the sensor is mounted has a plug including a sensor cavity that holds the sensor, and a fitting which is couplable to the pressure line. An isolator is used for transmitting the process pressure to the sensor through an isolator diaphragm acting on an incompressible filling the sensor cavity and transmitting pressure through a hole that is shaped to provide a flame quenching path. The passageway flame isolates the sensor from the process fluid line. The opposite side of the sensor is connected to atmosphere only through paths which are flame quenching because of the passageway shape. The plug is an assembly that can be made easily inserted and removed, and provides intrinsic safety even if there is failure of some of the components such as the isolating diaphragm or welds holding portions of the plug together.
