Abstract: With electronics and computers having taken over our business and personal lives by storm over the past 10 - 15 years, the very way that chart recordings are calculated could not be excluded from this ever present advancement. That is why Cascade Natural developed what we feel is the most efficient accurately repeatable chart reader on the market today. By combining a solid state camera and fiber optics this new chart reader can read up to three pen charts by distinguishing the color of the pen recordings with their function. And with the unique design and applicable software we are able to read orifice and displacement charts with nominal diameters of 8, 10 and 23 inches. But, what was I to say that hasnt been said before? That was my problem- It finally dawned on me, the technology itself has not really been addressed. Only what it does and how it is packaged. So, maybe there are a few items we can review today to provide you with a new insight into chart scanning. Any chart in general use by our industry, orifice meter, volume & pressure, specific gravity, temperature, pressure, one pen, two pen or three pen charts. How did this all come about? Well, the old phrase Necessity is the mother of invention best matches why a new technology became a usable reality.
