Corrosion monitoring and composition-analytical apparatus

An apparatus for continuous instantaneous monitoring of a selected component in a fluid system comprising gas, liquid, gas and liquid, liquid and solid, or a mixture thereof;

• said apparatus comprising a probe means connected to a pumping means;
• said probe means being removeably insertable into said fluid system and having a body portion and a diaphragm portion which will allow diffusion of said selected component defining a closed cavity which is evacuated and which connects to and communicates with said pumping means;
• said pumping means having an electrical molecule pumping means and a current indicating means which electronically removes molecules from said cavity, maintains evacuation of said cavity and indicates the molecule pumping rate as electrical current;
• said electrical molecule pumping means having at least two electrodes in a magnetic field with an electrical potential between said electrodes with one electrode being an anode and one electrode being a cathode so that molecules in said cavity pass into said magnetic field, are accelerated into an electrode and indicated as an electrical current;
• said probe having a geometry and size so that the probe can be sealably installed through a port in a vessel wall with the diaphragm portion of said probe exposed to said fluid system with the diaphragm portion of said probe being of such size, material, and configuration to allow selective diffusion of said selected component at a controlled rate;
• said current being transmitted to a receiving means as a signal and being indicated, recorded, or a combination thereof as a current magnitude;
• said signal being transmitted to a controlling means with an injector means which injects a composition into said fluid system to effect the selected component being monitored.
