December 20, 2013 Volume 1, Issue 2 Optical Scientific Incorporated The world leader in innovative optical sensors Special points of interest: OSI Offers Increased Efficiency for Combustion Process The need to meet the world wide demand for electrical power, and the need to control, if not reduce, greenhouse gas emissions has made increased efficiency of fossil-fuel power plants ever more critical. The new OFS 2000C for volumetric flow monitoring OFS 2000 air flow sensors, originally devel- oped in 1999, have been used to great effect in increasing accuracy on measuring exhaust gas emissions, enabling operators to meet EPA regulations with confidence. Now OSI offers an optical flow sensor scintillation measurement for combustion inflow air. The standard (outflow) OFS offers the most accurate and reliable airflow velocity of any sensor. In addition to velocity, the OFS 2000C provides volumetric flow, temperature, and pressure measurement capabilities to give the customer more precise control of the combustion process - all from a single source. Current power plants world wide generally operate at an average 28% efficiency with the best plants operating at 45% efficiency. A highly-efficient plant emits almost 40% less CO2 than the average. A big (and comparatively cost-effective) step in achieving this is in improving combustion control, and the key to that is having the best possible airflow metering available. OFS 2000C offers a low-cost highperformance answer. OFS 2000F Meets or exceeds new EPA Part J(a) And SCAQMD's Rule 1118 Originally rolled out in 1999, the basic OFS 2000 optical flow sensor became the choice for operators who wanted the most accurate measurement possible of stack outflow for Continuous Emission Monitoring Systems (CEMS). OFS 2000F was developed from that sensor and enhanced to cope with the more robust (and more sensitive) requirements of flare gas flow monitoring. With a NIST-proven accuracy of <1% and drift-free operation the OFS 2000F meets or exceeds the requirements of EPA 40 CFR 60 Subpart J(a) covering flare gas monitoring. In addition to SCAQMD (Southern California Air Quality Management District) Rule 1118. SCAQMD is renowned for having the most rigorous air quality regulations in the United States. > This is OSI’ Second issue of the Sight Lines newsletter.

Not right away. The Earth’s surface temperature does not react instantaneously to the energy imbalance created by rising carbon dioxide levels. This delayed reaction occurs because a great deal of the excess energy is stored in the ocean, which has a tremendous heat capacity. Because of this lag (which scientists call “thermal inertia”), even the 0.6–0.9 degrees of global warming we have observed in the past century is not the full amount of warming we can expect from the greenhouse gases we have already emitted. Even if all emissions were to stop today, the Earth’s average surface temperature would climb another 0.6 degrees or so over the next several decades before temperatures stopped rising. The time lag is one reason why there is a risk in waiting to control greenhouse gas emissions until global warming becomes worse or its effects more serious and obvious. If we wait until we feel the amount or impact of global warming has reached an intolerable level, we will not be able to “hold the line” at that point; some further warming will be unavoidable.

It is there, though, not hostile, not reluctant, not deaf. If you summon it by the right word, by its right name, it will come."

The analog output is a 420 mA current loop commonly used in industrial control systems. The digital output is ASCII text data string using RS232 communications format.

Ital Control has been a pioneer in the introduction to their market of technologies that only later would become standard - among the most prominent examples: thermal dispersion mass flow meters and coriolis mass flow meters for gases. Later, instrumentation for level measurement, process analysis, and emissions measurement were included. Now, Optical Scientifics' OFS 2000 Optical Flow Meters have been added to the product line. structured, well able to advise clients in the selection of instruments or analysis methods, and to provide support for installation, commissioning and maintenance.

Terry has been on our Engineering staff since 1993 and involved in every phase of product development for OWI, LOA, OFS - every one of our sensors. Along with everything else, Terry mans the tech support desk here. "The main reason I can do this is that, believe it or not, our stuff works - period. We've been building and selling sensors now for almost 30 years. There are literally thousands of sensors of all types: rainfall, visibility, present weather, air flow, all operating 24/7/365 and in some of the most hostile environments - and I comfortably at their desk, but out on bridge, catwalk, Maybe two or three times instrument tower, a smoke a month - and half of them stack, or a good distance from technicians or opera- from civilization anyhow; and they need help right tors who are new guys and just need a quick ori- then and there.
