  Instruments and analyzers for spectral DNI measurements

  Where the pyrheliometer is most suitable to quantify the total DNI of the solar spectrum. The spectroradiometer gives details about the energy distribution which is important for PV or CPV cell research. The solar spectrum wil change with the angle of incidence and its path through the atmosphere. Photons wil be reflected, scattered or absorbed. Big absorbers of infrared irradiance are water vapor, carbon dioxide, and ozon.

  Wet gas monitoring for refineries

  Thermal mass flow meters provide excellent measurement capabilities in dry gas flows. They have proven durability, accuracy, and repeatability. However, thermal flow meters are sensitive to liquid droplets in a wet gas stream. For a thermal flow meter to work accurately in a condensing gas environment, the probe must be placed far enough downstream so that the entrained water has condensed onto the pipe wall. In a very wet environment, any condensing liquid (commonly referred to as mist or fog) contacting the sensor probes causes a high reading due to the liquid vaporizing on the heated portion of the sensor. As a result of this deficiency, measurements with conventional thermal meters are largely ignored when moisture levels rise because there is no confidence that the measurements are true.

  Gas monitoring instruments and systems for process NOx measurement

  Nitric acid HNO3 is an important intermediate reagent for production of several important end products, such as fertilizers, explosives, dyestuffs/pigments, pesticides, pharmaceuticals, photographic materials, plastics, and synthetic fibers. At nitric acid manufacturing plants, the Gasmet™ FTIR Gas Analyzer can be used to measure several gaseous components from the process stream for purposes of process control. A single system can be used to measure the high levels of nitrogen monoxide NO and nitrogen dioxide NO2, as well as water vapor H2O, nitrous oxide N2O, carbon monoxide CO, carbon dioxide CO2 and ammonia NH3. The fixed installation products for these purposes are the Gasmet™ CEM II measurement system, and the Gasmet™ FCX Gas Analyzers, both of which utilize the FTIR measurement technique for simultaneous multicomponent analysis of the sample gas.

  Instruments and analyzers for DNI measurements with a pyrheliometer

  Solar Direct Normal Irradiance (DNI) represents the direct solar component and contains about 80% of the total solar energy budget on earth. Outside the atmosphere (AM0) the solar irradiance is considdered as a constant (1367 W/m2) that slightly fluctuates with a 11 year cycle. The DNI at the earth surface is highly variable due to the atmospheric conditions (clouds, aerosols, water vapor and molecules).

  Gas detection analyzers for wastewater treatment industry

  Regulations prohibit facilities from discharging flammable or explosive wastes from their processes into the wastewater collection system. These wastes are not only a fire and explosion hazard but they can also effect the efficient and effective operation of the treatment facility. PrevEx Flammability analyzers are used to continuously monitor the waste stream for flammable gases and vapors. Their unique design and operating technology make them the ideal analyzers for the harsh conditions found in the sewer environment.
