    Continuous Floating Roof Tank Condition Monitoring

    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...

    Accurate Level Measurement for Efficient & Reliable Boiler Performance

    If you’re unfamiliar with the phrase “ heat rate ” used in the electrical power generation industry, it means the amount of heat energy in BTUs as input to the turbine generators divided by the amount of electricity generated in kilowatts. Accurate level measurement in the boiler drums and feedwater heaters is critical to optimize efficiency and run the turbines reliably over time. Matt Brummer Level...

    Reducing maintenance and improving safety and reliability on supercritical steam lines

    The Mobrey Hydratect 2462 Water and Steam Detection System is the modern equivalent to float level switches and is suitable for process conditions of 4350 psi / 300 bar and 1040° F / 560°C. It is used on safety critical applications to detect the unwanted presence of water in steam, or the water level within a steam drum. A new Emerson case study details a typical application for the Mobrey Hydratect 2462. The...

    Solving stringent insurer safety requirements

    A waste treatment specialist company in France was using differential pressure (DP) transmitters to measure and control the level within their two steam drums. However, after a recent review, the plant’s insurers were concerned that if the DCS was to fail, the DP measurement would be lost and there would be no way of knowing the level within the steam drum. This could lead to the steam drum running dry, or rising...

    Reliable Level Measurement for Marine Vessel Tanks

    Measure tank levels can be challenging based on many factors including liquid composition, tank geometry, fill/empty rates, etc. And, if measuring levels on marine vessel tanks, there is added complexity with this non-stationary environment. I saw a LinkedIn post from Emerson’s Bert Konings about the complexities of level measurements in marine environments. In it, he pointed to this 5:26 YouTube video, Reliability...

    Solids Level Measurement Technology Selection Considerations

    Solids, unlike liquids, can have an uneven surface, making level measurement very difficult. In a Control Engineering magazine article, How to choose the right level instrument for applications , Emerson’s Lydia Miller shares tips on selecting the right level measurement technology for your application. Three primary factors you must consider include: Specific material characteristics Installation considerations...
