Some Foxboro Power Plant Instruments Power Plant Instruments 77 JlOXBORO POWER PLANT INSTRUMENTS Pigures 1 & 2 â Foxboro Recording and Indicat-ing Thermometers for power plants. Used on feed-water heaters, stacks, economizers, steam lines, ammoniacompressors, freezing tanks, condensers, forecoolers,brine lines, brine tanks. Figures 3 & 4 â Foxboro Recording and Indicat-ing Pressure Gauges for power plants. For use onboilers, steam lines, liquid lines and compressors. Figure 5 â Foxboro Two-Pen Recording Pres-sure Gauges for recording compressor suction and dis-charge pressures. Low pressure two-penrecorders areused for recording draft at any two parts of the boilersystem. For dairies whose power requirements necessitateplants of large capacity Foxboro-Heath COg Recordersproduce permanent records of the COo content in theflue gases. Their use greatly increases the efficiency andeconomy of plant operation. For large plants wealso recommend the use of Foxboro Triplex DraftG
