Boiler Water Conductivity Measurement Fundamentals

Heat exchangers are devices designed to transfer heat between two or more fluidsie liquids vapors or gasesof different temperatures Depending on the type of heat exchanger employed the heat transferring process can be gas-to-gas liquid-to-gas or liquid-to-liquid and occur through a solid separator which prevents mixing of the fluids or direct fluid contact
