    It's what you have all been waiting for! Our new handbook "The Engineer's Guide to Level Measurement" is now available! It is designed to support engineers applying level measurement to projects in the process industries. Request your copy by emailing: marketing.level@emerson.com

  • Measuring Low Dielectric Products with Guided Wave Radar

    Anonymous

    Radar level measurement is considered the “best practice” technology within a process plant.  However, there are still a number of challenges with it.  Foam, agitation and condensing liquids are not the easiest to measure.  As a result of improved radar...

    Guided Wave Radar (GWR) and non-contact radar is the most common technology for new level measurement applications.  While it has a number of advantages over other level technology a low dielectric product, foam and excessive agitation can present a ...

  • Guidance for Radar Level Measurement Applications

    Jim Cahill
    Recently we've had a few level measurement-related posts--one on a refinery desalter vessel application and another on guided wave radar setup, calibration, and diagnostics . To continue on this theme, I've discovered an article, Determining the level best in radar measurement , on the U.K.-based ConnectingIndustry.com website. Emerson's Sarah Parker highlights contacting and non-contacting radar level measurement application…

  • Transient Protection for Instrumentation

    Transient protection is one of the biggest challenges to instrumentation.  Lightning strikes, power surges and even static dissipation can cause significant damage to an instrument.  This is especially true for instruments that are outside and in remote...

  • Level Measurement for Control and Alarm

    A properly instrumented vessel will include a level measurement for both control and alarm notification.  This minimally requires a continuous level measurement of the process fluid.   Differential pressure (DP), radar and nuclear are all great technologies...

  • Measuring Raw Materials for Chemical Reactions

    The chemical reactions are the most critical processes in a chemical plant.  Reagents, catalysts and feedstocks are combined in chemical reaction vessels to produce other more valuable chemicals.  Sometimes these are finished products.  Other times these...

  • Tank Storage Wireless Level Measurement and Overspill Protection

    Jim Cahill
    Imagine being an operator for a Swedish tank storage facility aside the Baltic Sea and having to manually measure tank levels in the dead of winter. That’s exactly what operators at FH Tank Storage AB have had to do at the Kalmar storage terminal in a...

  • Avoiding Shutdowns with Accurate Level Measurement

    Jim Cahill
    For plants and mills that use steam in the production process, measuring the steam condensate level accurately can be the difference between operating reliably and fighting unplanned shutdowns. So was the case for a U.S. ethanol producer, Absolute Energy...

  • Nuclear Level Measurement

    Level measurement is often times the most challenging measurement in a process plant.  There are many technologies that can be used, including differential pressure (DP), capacitance, ultrasonic and radar .  Each of these technologies can be used in many...

  • Level Measurement with Foam

    Level measurement is often the most challenging measurement in a process plant.  Until ultrasonic and radar technology were introduced, level measurement was done with some type of contact technology.  Among these are differential pressure (DP), capacitance...

  • Eliminating Temperature Effects in DP Level Measurement

    Jim Cahill
    Differential pressure (DP) measurement has long been used in tank and other vessel level measurement. Level is calculated by taking the difference in pressure divided by the specific gravity of the liquid. I caught up with Emerson’s Anshuman Prasad, a...
