liquid-level indicator Applications

  • Measurement and control systems for the Indicating the level - mechanically

    Depending on the regulations, a steam boiler must be equipped with one or more direct and/ or indirect level gauges. With direct level gauges, the liquid level can be seen directly through a glass or mica window. The use of a transparent level gauge with background illumination gives operating staff a clear separation between the water and steam zones even when viewed at a relatively long distance. Bicolour level gauges (black and white or green and red) are very suitable for camera transmission to the measuring station because of their special design and the intense LED illumination. With indirect level gauges, the water level is transmitted by a magnetic system to a display panel on the outside of a pipe.

    Low level measurement of VOCs and Terpenes close to the sea and the Landes Forest

    It has been established that organic aerosol (OA) makes up for a major fraction of fine particulate matter in all region of the atmosphere. This fraction accounts approximately for half of the total PM2.5 dry mass.1,2 Primary OA is directly emitted in the troposphere from anthropological and natural sources whereas secondary OA (SOA) is formed in-situ in the atmosphere from the oxidation of biogenic or anthropogenic gas-phase precursors and subsequent partitioning of the less volatile products into the particle phase. The current number is that, on a global scale, SOA would represent around 60% of the overall OA.3 However, recent global mass-balance estimations for the removal of volatile organic compounds (VOC) suggest that this number could under-predicts SOA production.4 Recent field measurements in urban locations are also in support of a larger share, indicating that SOA is the dominant fraction of OA, with amounts considerably 20 greater than models predictions.
