  • Monitoring Gas Emissions from Volcanoes to Predict Volcanic Activity

    To understand and predict the behaviour of volcanoes an increasing number of scientists are combining geological monitoring and geochemical models. By measuring and monitoring the prevalence of gases like CO2, scientists hope to be able to better predict the likelihood of volcanic eruptions. In 2010 Iceland’s Eyjafjallajökull volcano erupted, releasing 250 million ...

  • LED Applications for Oil and Gas Refining and Processing

    Oil and gas processing facilities are unsafe due to the existence of hazardous compounds during operations. When addressing such issues, companies in the sector may deploy explosion proof lighting systems to prevent the ignition of sparks created from the electrical equipment. The adoption of LED technology in oil and gas refineries has helped reinforce key safety measures associated with ...

  • Low energy mixing to optimize anaerobic digestion at the Kitchener WWTP

    The existing Kitchener Wastewater Treatment Plant (WWTP) is a conventional secondary treatment facility, with a rated capacity of 122,745 mVd. The plant is comprised of two separate secondary treatment plants (Plant 1 and Plant 2) served by a common headworks facilities and primary clarifier facilities. Plant 1 was constructed in the early 1960s and Plant 2 was constructed in the mid-1970s. Both ...

  • How a Specialized Automatic Control Valve Solved Flooding

    The Colombian area of Antioquia creates much of its clean power from hydropower plants along the Guadalupe River. The Guadalupe IV hydroelectric plant generates power with three vertical axis turbines that discharge water below the river level. To prevent flooding, however, the plant needed a solution that ensured the ejector ...

  • Fire Codes: A Foundation of Safety for a Rapidly Changing World

    Chief among these safety features is fire protection. There are myriad codes and regulations relating to fire safety in commercial buildings, from standards on portable fire extinguishers to the installation of stationary pumps for fire protection — the U.S.- based National Fire Protection Agency (NFPA) alone has more than 300 consensus codes that have been adopted in whole or in part ...

  • Using Electromagnetic induction to characterize soils - Case Study

    Electrical conductivity measurements have been used for years to determine salinity and moisture in soils. Probes were inserted directly into the soil to determine how well the soil conducted an applied current. This process was slow and labor-intensive and was usually reserved for scientific studies. A more recent technique for measuring conductivity is electromagnetic induction (EM), a ...

  • Water quality measurement extreme

    Background The characteristics of the Rio Tinto in the south-west of Spain, near Sevilla, are his ruby colour and the extremely sour pH-value between 0 and 2 pH-units. The river carries a mixture between poisonous heavy metals like copper, nickel, arsenic, iron and cadmium, dissolved in high-percent sulphuric acid. It’s not proved where these unusual conditions come from. As per current ...

  • Measurement of hydrocarbons in produced water using fiber optic sensor technology

    Due to the non-availability of Freon, there is need for an alternative method to measure the concentration of hydrocarbons in the effluent from oil water separators in use in the oil industry today. Current methods use solvent extraction and IR analysis of water samples. In this paper we present an alternative method, which does not use any solvents and can provide in-situ analysis of the ...

  • Optical measurement of oxygen concentration in water

    The optimisation of oxygen transfer is a key element of control and regulation strategies in municipal and industrial sewage treatment plants. In 2003, HACH LANGE became the first instrument manufacturer to launch the LDO (Luminescent Dissolved Oxygen) method for determining dissolved oxygen in water. The LDO technology is based on pulsed blue light, which brings benefits such as high precision, ...


  • Get the scoop on the newest technology for the measurement of pH

    SENTRON had its 20th birthday in April 2005 and is world wide known as the manufacturer of glass free ISFET (Ion Sensitive Field Effect Transistor) pH systems. During the 20 years we developed and manufactured not only ISFET pH sensors but also pressure sensors in our own silicon chip production facility. This facility for development and manufacturing of solid-state sensors, enables us to ...

  • Two Technologies for Flow Measurement from Outside a Pipe

    Doppler and Transit Time are two very popular types of flow meter for non-invasive measurement of flow in full pipes. We tend to confuse these technologies because they are both ultrasonic and both measure flow by using sensors clamped onto the outside of a pipe. In the real world they actually work best in opposite applications. Success in your installation depends on understanding the ...

  • New Process Gas Analyzer for the Measurement of Water Vapor

    KEYWORDS TDLAS, WMS, Laser Spectroscopy, Water Vapor Measurement, Gas Analyzer ABSTRACT A new analyzer for the measurement of water vapor concentration based on Tunable Diode Laser Absorption Spectroscopy (TDLAS) was developed. The water-vapor line at 1854-nm was selected for the measurement, and the performance of the system was evaluated on different ...

  • Water Pressure Measurement with Time Domain Reflectometry Cables

    Attributes of the remote measurement of piezometric water pressure and water level with time domain reflectometry (TDR) techniques are investigated. The evaluation includes a two-wire system for unusually small riser tubes as well as parallel wire and air-filled or hollow coaxial cable for typical installations. Comparison of TDR cable and commercial pressure transducer technology shows coaxial ...

  • Ultrapure water – The standard for resistivity measurements of Ultrapure water - Case Study

    Abstract For years, resistivity/conductivity2 instrumentation has been used as a reliable indicator of ionic water quality, especially for ultrapure water (UPW). Traditionally, the instrumentation is procured, installed, powered up, and perhaps connected to a PLC, strip chart recorder, or a LAN. After that, the instrument and sensor receive no attention until a problem arises. Today, ...

  • Online flow measurement

    Background The undershoot weir in Hohensaaten was built in 1913. It has three openings and regulates the discharge from the Oderbruch and from the Finow canal into the Hohensaaten-Friedrichsthaler-waterway. Moreover, it protects parts of the Oderbruch against Oder floods. The weir controls the waterlevels in the Havel-Oder-waterway and in the reach of Niederfinow- Hohensaaten. ...
