  • Mass flow sensing improves leak test efficiency

    Mass flow meters reduce risk of measurement error and provide a reliable, quantitative measurement of product quality and production process control. In the leak testing application, mass flow meters offer advantages unmatched by other instruments. Today, leak testing must be not only precise, accurate and irrefutable, but also easy-to-use, fast and efficient. With mass flow sensing, dry air ...

  • Performance-Based Specification Of Electrical Leak Location Surveys For Geomembrane Liners

    ABSTRACT Electrical leak location surveys can be a crucial part of the final quality control of geomembrane liner installations. The method has been offered as a commercial service since 1985 and is the only practical test method that can find holes in the liner after protective soil cover is put on the liner. During the past fourteen years the test method has been used on a wide variety of ...

  • Rapid Analysis of Petroleum Hydrocarbons (TPH) in Soil and Water by Infrared Spectroscopy

    In 1988 the US EPA estimated that there were 3 to 5 million underground chemical storage tanks (UST’s) in the United States, of which up to 1% would develop leaks every year. In response to growing concerns about the quality and future availability of safe drinking water, federal and state programs have begun to systematically replace virtually all UST’s installed before 1986 either with above ...

  • Gas process automation

    Problem: Many relatively simple industrial or laboratory processes that require control of flow or pressure can be greatly improved with automation. Using a mass flow controller to control a certain gas flow rate, for instance, is far more precise and has a faster speed of response than manually adjusting a needle valve while consulting a pressure gage. Such processes can be automated ...

  • On-Site Analysis of Gasoline Range Organics (GRO) in Soil and Groundwater Using Field Portable Purge and Trap GC / FID / PID

    Although leaking underground storage tanks account for the majority of gasoline contamination in soils and groundwater, other events such as accidents during product transportation or delivery are also significant. Spill clean-ups and tank replacements have an immediacy to them due to the very steep relationship between delay and cost. Since gasoline is highly mobile in the environment, it is ...

  • A Simplified Procedure for the Determination of TPH’s in Waters and Soils Using the HC-404 System

    The determination of Total Petroleum Hydrocarbons (TPH), greases, and lubricant residues are important environmental and industrial tests. Fuel and lube oils can be determined in water and soils to track spills and storage tank leaks, while many military and industrial situations require certain components (gas regulators, space shuttle components, weaponry parts, etc.) to have a maximum limit of ...

  • Typical Sensor Location Considerations

    The sensor mounting location within a space may be dependent on many variables. There are no specific formulas since each application will have it’s own determining factors and priorities. These include, but are not limited to: source of gas: Is the source a combustion exhaust from a vehicle or furnace or a vapour from a tank spill, pipe leak, or faulty valve? density of ...

  • In-Situ Treatment - Funnel & Gate System - Case Study

    Problem An asphalt testing facility, in operation for many years, closed in the early 1990s. A subsequent environmental assessment revealed that an underground storage tank, used to hold common cleaning/degreasing solvent for use during testing, had developed a leak and had to be abandoned. The storage tank and soil in the immediate vicinity was removed as the first step to remediate ...

  • Case study - EPH in soil with No. 6 fuel oil

    No. 6 fuel oils (heavy fuel oil, bunker C oil) is often used in industry for heat, steam or power generation. A consultant used Sitelab to investigate two different spill sites contaminated with subsurface plumes of NAPL resulting from leaking underground storage tanks (USTs). Soils were collected from borings using a drill rig and field screened for their EPH aromatic content. Split samples ...
