Petrochemical Industry Tank Level Gauging

Composition and remaining volume of oil in a tank are crucial information when gauging the tank level. FOTRIC 348A advanced thermal cameras can be used to accurately measure levels of oil tanks from safe distance away, so as to validate results for other measurement methods.


Customer's Challenge

Tank level gauging plays an important role in oil and gas industry. The facility management team not only need it to know when to refuel the tank, but also to identify the location of different interfaces in oil. Because the content of crude oil is not consistent, there are often layers of substances, such as solid, liquid, sludge, foam and vapor.


Composition and remaining volume of oil in a tank are crucial information for estimating the value and loading capacity needed to transport the remaining oil. While, except for Liquid level meter which might be less trustable due to dust pollution, other traditional gauging methods like strapping and stick dipping can be inaccurate and dangerous.


The Solution

FOTRIC 348A advanced thermal cameras can be used to accurately measure levels of oil tanks from safe distance away, so as to validate results for other measurement methods. FOTRIC 348A with 40mk sensitivity and 640x480 resolution, can clearly differentiate between solids, liquid and foam based on small temperature difference caused their varying heat capacity.


Its laser distance ranger are used to measure the tank level on camera’s screen, which is very welcome by site engineers.



The Result

By enabling users to determine morphology of objects in tank and make more accurate volume estimations, FOTRIC handheld thermal imager effectively prevent sludges from getting sucked into pumps, which will likely cause impeller failure.


In addition, clear estimation of sludge’s volume can help companies plan ahead and manage their downtime clean up accordingly.
