  • Flow Profiling on Demand – Illuminating the reservoir with Silixa’s intelligent Distributed Acoustic Sensor (iDAS) and ULTIMA Distributed Temperature Sensor (DTS)

    As energy demands increase rapidly, the goal of energy companies is to maximize ultimate recovery in an economically sound manner. One critical capability is the accurate measurement and monitoring of production from individual layers / perforated intervals in a multi-zone completion. This data allows operators to optimize zonal production, improve recovery, increase production per well and ...

  • Group method of data handling and neural networks applied in temperature sensors monitoring

    In this work a monitoring system is developed based on the Group Method of Data Handling (GMDH) and Artificial Neural Networks (ANNs) methodologies. GMDH creates non-linear algebraic models for system characterisation and ANN is a massively parallel distributed processor made up of simple processing units called neurons. The monitoring system was applied to the IEA-R1 research reactor at ...

  • Distributed Measurements Unlock the Future of Design

    The next generations of materials and design will require sensing technologies that can monitor beyond the scope of point sensors such as thermocouples and strain gauges. New sensing platforms based on optical fibers can obtain spatially continuous, real time data, giving developers detailed insight across broad areas into how their materials and designs behave. Such systems also can sense ...

  • Effective Temperature Control for Cement Kiln Off-Gases

    INTRODUCTIONEffective off-gas temperature control without unwanted side effects can be achieved in many cement plants with state-of-the-art evaporative spray technology. Gas temperatures have elevated in recent years from as low as 180°C to over 370°C. This is coincident with a higher proportion of 'dry' operation kilns. Evaporative cooling water sprays in conditioning towers, ducts or at the ...


  • PureAire Makes Oxygen Monitor for Nitrogen Generators

    Nitrogen generators are most commonly used in areas where on-demand nitrogen is preferred rather than, storing liquid nitrogen (LN2) in cylinders.  Nitrogen generators have a lower cost of operation, and can be used where smaller amounts of nitrogen are needed. Nitrogen generators are used in the pharmaceutical industry, testing laboratories, cryogenic facilities, welding manufactures, and ...

  • Data assimilation for crop yield and CO2 fixation monitoring in Asia by a photosynthetic sterility model using satellites and meteorological data

    This study assimilates satellite and meteorological data to monitor grain yields and CO2 fixation by developing a photosynthetic-sterility model that integrates the Asian scale of meteorological data such as solar radiation, air temperature effects on photosynthesis and the Normalised Difference Vegetation Index (NDVI) with a Satellite Pour l'Observation de la Terre (SPOT) VEGETATION sensor. ...

  • New Developments in Thermal Dispersion Mass Flow Meters: In-The-Field Compensation for Changes in Natural Gas Composition

    Introduction The flow of natural gas in pipelines is often complicated by changes in the composition of the gas. The method described in this paper solves the problem of variable composition via a new four-temperature mass flow sensor. The new (low sensor feeds its measurements into the algorithms of an advanced mathematical model that includes gas properties in its calculations. The method ...

  • A step closer toward maintenance-free gear

    Abstract—A difficult-to-predict electrical failure is the continuity failure. Pressure junctions are common problem sources for continuity failures. Available tools to search for pressure-junction problems include low-resistance testing, temperature monitoring using physical contact between sensor and heated part, pyrometer temperature monitoring, infrared photography, and visual ...

  • Continuous Oxygen Monitor Detects Leaks in Nitrogen Dewar Storage

    Extremely low maintenance oxygen (O2) monitor designed to continuously monitor confined spaces for low oxygen levels available from PureAire Oxygen Monitors. PureAire Oxygen Monitor is suitable in all environments containing nitrogen, helium, argon, or any cryogenic gases. PureAire is unaffected by temperature, humidity, barometric pressure, or any environmental changes. The instrument displays ...

  • Snow cover mapping using IRS-P6 AWiFS data and the relationships between some climatic factors with snowpack in the northwest of Iran

    In this study, we explored the potential of the multispectral and multi-temporal IRS Advanced Wide Field Sensor (AWiFS) data for mapping of the snow cover in the northwest regions of Iran. The AWiFS snow cover maps, based on the unsupervised classification method, were compared with the estimates of snow cover area derived from the moderate resolution imaging spectroradiometer (MODIS) images ...

  • Oxygen Monitors for the New Millennium

    Oxygen monitors have become a required piece of safety equipment for many industrial and laboratory environments, where the release of certain toxics can create an area unsafe for living beings (human or animal).  When making a purchasing decision on any oxygen detection monitor, one need look no further than the sensor cell found at the heart of the monitor.  While each oxygen ...

  • Influence of the shear stress and salinity on Anammox biofilms formation: Modelling results

    Anammox biomass has a relatively long duplication time and low yield. This is an advantage because the production of surplus sludge is reduced; however it also implies that the process must be operated in reactors with very good sludge retention. Some of the systems used to improve biomass retention are based on biofilm reactors; therefore, the objective of this work was to study the ability of ...

  • Chlorine mystery solved

    Following the installation of in-pipe drinking water quality monitoring sondes, distribution engineers discovered an occasional significant disparity between the Intellisondes’ data and results from grab samples tested by a photometer tablet (DPD) method. For most of the time, there was close agreement between the two methods, but periodically, the photometer results varied wildly, whilst ...
