StackOp Opacity Meter 

StackOP opacity meters, detect and measure the amount of light blocked in smoke emitted in large stacks from industrial operations. The smoke meter readout displays the smoke density giving a measure of the efficiency of combustion. This makes the stack opacity meter an excellent diagnostic tool to ensure proper maintenance of industrial process for improved fuel economy and protection of the environment.

Felix StackOp Opacity Meter

The StackOp meter is specifically for dynomometer test cells and stationary testing of stack emissions. The LCD displays opacity in percentage value, and the analog output at the rear of the unit outputs 0-1 VDC that corresponds to a digital readout. This analog output is used to go to a data acquisition system or a chart recorder. It comes complete with a PC interface cable and software set, that allows the user to download stored test results to a PC for archiving or printing. The control unit can be either portable or rackmount depending on the application.

Features

  • 100 tests can be stored.

  • Simple, portable with high reliability.

  • High accuracy in both artificial and direct lighting.

  • Sensor styles available for various application.

  • Allows for testing in both a "snap -idle" mode, or "follow mode.

  • Full flow or partial flow sensor heads using same transmitter & receiver.

The partial flow sensor head
Partial flow head is made of light weight anodized aluminum having a straight and curved nozzle for easy placement on various stack systems. The smoke plume is passed through the optics, without the need for a fan. The partial flow head allows for quick and easy placement of the sensor on the stack. By slipping the bayonet style nozzle into the stack the effect of wind during the measurement can be suppressed.
Felix StackOp Opacity Meter
The full flow head
Opacity is measured directly across the diameter of flange. Stack Pieces are available in a variety of sizes. Standard stack size for an in-line is 8”. Custom stack pieces are available in any diameter upon request. The standard material is schedule 40 carbon steel. Stainless steel is also available upon request. Connections may be flanged or welded.

Felix SO2 Sulfur Dioxide

UV Fluorescence SO2 Analyzer uses the proven UV fluorescence principle, coupled with state of the art microprocessor technology to provide accurate and dependable measurements of low level SO2. Exceptional stability is achieved with the use of an optical shutter to compensate for PMT drift and a reference detector to correct for changes in UV lamp intensity. A hydrocarbon "kicker" and advanced optical design combine to prevent inaccuracies due to interference.

Felix NO Analyzer  NO/NO2/NOX Analyzer uses Chemiluminescence which is the best practical analytical method for NOx detection. When an NO (nitric oxide) molecule reacts with ozone, it is oxidized to NO2, in an excited state. A small fraction of the molecules in this excited state decays by emitting a photon (i.e. giving off light) in the near infrared portion of the spectrum. The concentration of NOx in the sample is determined by the amount of light emitted from the mixed gas sample. This technique provides an extraordinarily sensitive, selective, and linear measurement of NOx.

Felix CO Analyzer 

CO Analyzer measures carbon monoxide by passing infrared light through sample and determining the absorbed energy and then compare this to that absorbed by a reference gas. This is accomplished with a Gas Filter wheel which alternately allows a high energy light source to pass through a CO filled chamber and a chamber with no CO present.

Felix Ozone Analayzer  The Ozone Analyzer is a microprocessor-controlled analyzer for measuring low ranges of ozone in ambient air. An Ultraviolet light is passed through a sample cell. The light is absorbed, depending on the amount of ozone present. The true value of the ozone is proportional to the absorption.

Felix NH3 Analyzer  Chemiluminescent NH3 Analyzer measures ambient ammonia in selectable ranges from 0-50 ppb to 0-2,000 ppb using the chemiluminescence principle and an API designed external ammonia converter and sampling system Ranges are user selectable in 1 ppb increments and auto ranging is available. Ammonia is difficult to measure accurately because of a tendency to be absorbed into other materials.
