  • Level Blog: Level Sensor Safety Proof Testing

    Jim Cahill
    Backing up your computer or server is a waste of time if restoring the backup fails when you need it. Good practice is to test these backups on separate test systems periodically to make sure they restore properly. Similarly, safety instrumented systems (SISs) need to assure that each safety instrumented function (SIF)/safety loop does what it’s intended to do to bring the plant to a safe state in the event of a demand…

  • Analytical Experts Blog: Get Better Overfill Protection with 2-in-1 Technology

    Bonnie Brown
    By Johan Sandberg, Safety Expert, Emerson Automation Solutions As you know, overfills are a major problem to the process industry in general, but especially so for bulk liquid storage tanks where the consequences can be catastrophic. The industry and society in general are currently investing considerable resources to increase the safety at tank farms. Today the basic overfill prevention technology at many facilities…

  • Level Blog: Remote Partial Proof Testing Level Sensors

    Jim Cahill
    For safety instrumented functions (SIFs), proof testing is the process of identifying undetected dangerous failures in the sensor, final control element and logic solver which comprise the SIF. Dangerous failures are those that could put the safety instrumented system (SIS) in a hazardous or fail-to-function state. If undetected, in the case of level measurements, this could lead to an overfill and spill, with potentially…

  • Level Blog: Increasing safety through remote proof-testing

    Peta Glenister
    The proof-testing of safety instrumented systems in liquid level measurement applications has traditionally relied on workers in the field. However, our latest technology advancements in modern smart devices is enabling this vital task to be performed remotely, bringing significant safety, efficiency and cost benefits.

  • Level Blog: Using Flushing/Drip/Calibration Rings in Pressure and Level Measurements

    Jim Cahill
    If you work with pressure measurement instrumentation, you may have heard the phrases drip rings, flushing rings or calibration rings. These are used for pressure and differential pressure (DP) level measurement devices where diaphragm seals are used. I bring this up because I received an email recently that asked about these [edited and paraphrased to protect confidentiality]: Can you advise where in the Emerson…

  • Analytical Experts Blog: Delivery Solves the Problem

    Bonnie Brown
    By Sherri Renberg, Global Integrated Marketing Manager, Emerson Automation Solutions I’m sharing an unusual Analytic Expert post with you today. As you know, we typically discuss technologies and application solutions, but today I’m going to talk about delivery. You just need to spend a moment ordering something on Amazon Prime to know that the delivery expectations of people have changed enormously and what applies…

  • Level Blog: Continuous Floating Roof Tank Condition Monitoring

    Jim Cahill
    Floating roofs are used on storage tanks to minimize vapor space between the top of the tank and the level of the liquid, typically a petroleum-based product, inside the tank. Per the External floating roof tank Wikipedia entry: The roof rises and falls with the liquid level in the tank. As opposed to a fixed roof tank there is no vapor space ( ullage ) in the floating roof tank (except for very low liquid level…
