The AQM4 is an ideal instrument for indoor air quality (IAQ) diagnosis. The portable AQM4 uses NDIR (non-dispersive infrared) technology for CO2 measurement to ensure reliability and long-term stability. It is useful in verifying HVAC systems performance and air ventilation control. Poor indoor air quality causes tiredness, inability to concentrate, and even illness (ex. Sick Building Syndrome). IAQ monitoring and surveying especially for CO2 levels and air ventilation It is also recommended for regulating standards of industrial air quality in some countries.

  • Air Flow Meter
    // THE AIR FLOW METER The task of the MAF sensor to minimize the intake air return flow and prevent The Mass Air Flow Sensor (otherwise known as the deposition of particles on the sensor element. MAF Sensor, Air Mass Meter or Mass Air Flow Meter) is installed between the air filter and the throttle valve and measures the air delivered to the cylinders of the engine. In the case of petrol engines, the intake air mass is the most important value for calculating the required fuel mass. In the case of diesel engines, the measured value in the partial load range is used for controlling the ex- haust gas recirculation, while in the full load range for black smoke limitation. The engine con- trol unit (ECU) calculates the maximum injection quantity, which can be burnt without producing smoke. How the MAF sensor works The sensor element detects only a part of the entire air mass. In the example shown (Fig.1) there is a channel, the shape of which is intended Figure 2: The sensor element of MAF sensor. Source: NTK Today's MAF sensors consist of a heating resistor and two temperature sensors (Fig.2). The heating resistor is held by the electronics at a constant temperature of about 160 degrees. The incoming fresh air cools the temperature sensor T1 and is heated by the heating resistor. Therefore a higher temperature is measured at temperature sensor T2. The electronics calculate the air mass from the temperature difference and convert the calcu- lated value into an electrical signal for the ECU.

  • Removal of Volatile Organic Compounds from Soil
    Water Pollution X 107 Removal of volatile organic compounds from soil R. S. Amano University of Wisconsin-Milwaukee, USA Abstract Pollution by petroleum products is a source of volatile organic compounds in soil. Therefore, laboratory column venting experiments were completed in order to investigate the removal of a pure compound (toluene) and a mixture of two (toluene and n-heptane) and five (toluene, n-heptane, ethylbenzene, m-xylene and p-xylene) compounds. The choice of the compounds, as well as their proportion in the mixture, was made on the basis of the real fuel composition. The objective of this study is a comparison between the experimental volatile organic compounds removal results and the computational fluid dynamics (CFDs) analysis. The proposed model for the contaminants transport describes the removal of organic compounds from soil, the contaminants being distributed among four phases: vapor, nonaqueous liquid phase, aqueous and “solid”; the local phase’s equilibrium and the ideal behavior of all four phases was found to be accurate enough to describe the interphase mass transfer. The process developed in the lab consists of a heater/boiler that pumps and circulates hot oil through a pipeline that is enclosed in a larger-diameter pipe. This extraction pipe is vertically installed within the contaminated soil up to a certain depth and is welded at the bottom and capped at the top. The number of heat source pipes and extraction wells depends on the type of soil, the type of pollutants, and the moisture content of the soil and the size of the area to be cleaned.
