  • Selecting the Right Point Level Switch to Prevent Dangerous Spills of Solids Materials from Vessels and Silos

    Jim Cahill
    If you have vessels and silos containing solids materials such as cement, grains, wood chips and plastic pellets, it is vital to prevent overfills. Should an overfill result in a spill, the consequences can be extremely serious, with falling materials having the potential to cause injuries or even fatalities. In addition, product can be wasted, production time lost, environmental fines incurred, and the vessel or silo…

  • Pump Health Monitoring Interactive Virtual Webinar

    Jim Cahill
    While processes have been monitored with sensors for many decades, advancements in technology, especially with the Industrial Internet of Things (IIoT) , has made monitoring for improved safety, efficiency, and reliability much more achievable than in the past. For example, in many plants, pumps that are considered non-critical are not monitored. These are either infrequently manually inspected or run to failure. Today…

  • Low Dielectric Radar Level Measurement

    Jim Cahill
    Guided wave level measurement technology works by sending low-energy microwave pulses along a metal probe which is then reflected by the surfaces. The probe is in direct contact with the media and detects a level when reaching a media with a different dielectric constant. It calculates the distance to the surface, which is then subtracted from the total length to calculate the level. For applications with fluids with…

  • Tips for Accurate DP Level Measurements

    Jim Cahill
    Nicole Meidl Differential pressure (DP) for liquid level measurement works by measuring the hydrostatic head pressure at the bottom of the vessel and the specific gravity of the liquid.

  • Successfully Applying Non-Contacting Radar in Black Liquor Mixing Tanks

    Jim Cahill
    In the Kraft pulping process, wood fibers are separated, and resinous materials removed, using an alkaline (typically sodium hydroxide and sodium sulfide) cooking liquor, also known as white liquor. This process converts wood into cellulosic pulp used in the papermaking process. This digesting process turns the white liquor into black liquor, which contains : …lignin fragments, carbohydrates from the breakdown of…
