I would like to ask what type of level gauge is suitable for use in atmospheric pressure tanks with internal floating roofs?

The gravity of the floating roof needs to be removed; a single-flange design will suffice.

I would like to ask how the gravity of a floating roof is transferred? Is it sufficient to subtract the weight of the internal floating disk itself from the pressure measured by the single-flange pressure transmitter?

If you need a single-flange transmitter, please visit our website at WWW.JSRTYB.COM to take a look

I recommend using a 26G radar level gauge, which will yield better results, installed at the 1/2R position.

Guided wave radar level gauge, photoelectric level gauge, servo level gauge

Radar level gauge with waveguide!!! Our factory is using it!!

Is the owner’s storage tank already built? Still making it from scratch? 1. For old tanks, it is recommended to use a single flange; the weight of the floating disk can be transferred away, and special attention should be paid to the location of the liquid level openings. Reason: Just one hole is needed, which makes construction and installation easier. 2. For new tanks, it is recommended to use guided wave radar; the guided wave tube should be installed during tank construction, running through the floating platform all the way to the top, with 80 holes typically provided. Reason: It offers higher precision than single-flange types, making future maintenance easier; moreover, guided wave radar is now available at a lower price. Recommendation: ROSEMENT offers process guided wave radar; the model is presumably from the 5500 series, with a price of around 15,000 to 20,000.

In principle, the single-flange differential pressure should be inaccurate, because the floating disc is subject not only to gravity and buoyancy but also to friction
