  • TLC meter “how-to” video: two-point user calibration

    A Solinst TLC Meter measures water level, temperature, and conductivity. To ensure accuracy of readings, the user can easily calibrate the Meter for conductivity, as required. User calibration allows for adjustment of a TLC Meter if the probe has been altered slightly due to mechanical, biological or chemical affects. If a TLC Meter is tested in standard calibration solution, and the readings are ...

  • Determining Bentonite Content in Soil-Bentonite Mixtures Using Electrical Conductivity

    A procedure based on electrical conductivity is described for measuring bentonite content in soil-bentonite mixtures having a wide range of bentonite contents. Standard equipment used for sedimentation analysis and an electrical conductivity meter are required. The procedure employs calibration curves relating electrical conductivity and bentonite concentration for soil-bentonite-water slurries. ...

  • 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 ...

  • Flow Tip Video: Learn Why Ease-of-Use is Critical for Flow Meter Selection

    Many times scientists and researchers spend more time setting up equipment and instrumentation for their experiments than conducting actual experiments to gather important data. This holds true for flow meters and controllers to measure and control gases to experiments. Some flow meters are very cumbersome with no display, can only measure one ...

  • What is TDS?

    Answer: Total Dissolved Solids (TDS) is a measure of the combined content of all the inorganic and organic substances such as mobile charged ions, minerals, salts or dissolved metals in a volume of liquid. Normally TDS is used in water testing, where TDS is defined as anything present that is not pure water (H2O) molecule or suspended ...

    Are those inexpensive iPad sound measurement apps any good? Are they as accurate as a properly calibrated $2,000 type 2 sound level meter? Let's review three separate studies, and an article: Study #1 In early 2014, NIOSH reviewed 192 sound measurement apps. NIOSH concluded, ...

  • Borehole logging case study

    Corozal, Puerto Rico GeoView was tasked to conduct borehole geophysical logging of at a groundwater extraction well in the rural area of the Municipality of Corozal, Puerto Rico. Prior groundwater tests indicated possible contamination of the groundwater. The study area was primarily underlain by stratified, mostly dark gray basaltic tuff, andesite and basalt porphyry rocks assigned to ...

  • Cost Containment: Beyond the Obvious

    Utilities today can implement a number of different initiatives to help them contain costs and maximize profits. Some of those, such as switching to a more efficient fuel source if possible, can produce obvious results that are relatively easy to calculate. But there are other initiatives, though less obvious, that can produce significant results at the bottom line. One such cost-containment ...

  • ITS marketing manager quoted in WaterTech

    Professional, ethical testing will start you off on the right foot and will directly determine which services the customer may need. Many substances could be in a customer’s water, but, “It’s not necessary to test for every parameter; that’s what labs are for,” advises Rob Samborn, director of sales and marketing for HM Digital, a Los Angeles-based maker of water ...

  • TDS: `The Done Sale`

    Many Americans have at least some concern that their tap water is problematic, yet they don’t know where to begin. The TDS, or total dissolved solids, meter can be the first step in determining if there’s a problem. The term TDS has long been well-known in the water treatment industry, yet still has not penetrated the mass consumer market. However, by hearing your brief explanation, ...
