ADDITIVE INJECTION SYSTEM, SYSTEM TO CONTROL A QUANTITY OF A FIRST FLUID, METHOD FOR MIXING A FUEL ADDITIVE AND EQUIPMENT TO MIX A QUANTITY OF A FIRST FLUID IN THE MAIN CURRENT OF A SECOND FLUID
An injection system and method for blending an additive into a main fluid flow stream at a controlled ratio, characterized by a controller (25) wherein the electrical circuitry thereof is contained in an explosion-proof housing (60) having a window (63) through which electromagnetic energy, such as an infrared command signal, can be transmitted. The circuitry contained within the explosion-proof housing (60) includes a receiver for receiving the electromagnetic energy transmitted through the window (63) and a processor or processors for decoding information included in the electromagnetic energy and for carrying out one or more functions based on such information. Also disclosed is an additive injection correction technique, a clean line technique and related and other features of the system and method. MATH MATH
