Issues with the dual-level gauge installation in internal floating roof tanks
Thread Content
The storage and transportation facility in question currently has only one set of level gauges for its internal floating roof tanks, either radar or fiber optic types. However, these level gauges often malfunction and require frequent repairs; in addition, staff must perform manual level checks, which is a time-consuming task. It would be useful to install two level gauges that can serve as backups to each other, thereby reducing the need for manual level checks. Currently, the most common type of level gauges—radar, fiber optic, and servo types—all require the use of guide tubes. Internal floating roof tanks also need to have access points for level checking. For dome-shaped tanks, these gauges can be installed on the light-transmitting openings. Are there any good solutions? Everyone’s opinions are welcome. PS； It seems that using dual level gauges in storage tanks is also a trend in the future. Those who work at new refineries or oil depots might be able to share their insights as well
Thank you for your reply. I’m not very familiar with differential pressure level gauges; I’ll wait until I understand their working principle and installation requirements better before replying. What is popular isn’t necessarily the best option, but it certainly has its advantages. The methods used to measure liquid levels based on various theories are also constantly evolving, and we have reason to believe that technology will continue to advance
Hello, a servo level gauge from Tokyo Kikō is showing values that fluctuate between -100mm and the normal level on the DCS. I’m wondering what could be causing this issue. I appreciate your response. Thank you.
Installing a steel belt level gauge will work just fine; is it really necessary to use a radar? It still doesn’t work.
Thank you for the analysis. Next time I go to work, I will consider the factors you mentioned. There has been no material flow into or out of this tank’s liquid level for a long time; I can use one of the Rosemount devices as a reference. It is likely that there is a problem with the hardware, as you mentioned. Thank you again
