Lights On
Another light painting shot from the darkness of the power plant. Every power plant seems to have these circular plots strewn all over the floors. I beleive that the machine on the right used these somehow. I'd be interested if anyone knew the purpose of the machine and the plots.
These are used to record gas or steam temperature, pressure & flow. The paper chart attaches to the machine & rotates, as the pens draw lines on the chart, which has graduations on it, to record the information. Also used in the oilfield.
Great site, awesome pics! Thanks for posting them!
