Gauge well float for floating roof storage tanks Chevron
In a floating roof tank including a tubular gauge well having a plurality of slots spaced along the length thereof to permit sampling of the liquid at various levels in the tank, a device for minimizing evaporation through any of the gauge slots that are located above the level of the liquid while being adapted to be readily removed to enable samples of stock in the tank to be taken through the gauge well

Tank Gauging Basics Varec
When mounting a servo or radar gauge on a floating roof tank, a gauging platform is required in order to mount the gauge over the product. This may be the tank roof on covered internal floating roof tanks or an actual platform that extends out from the tank wall over an open roof tank. Many platforms provide a stilling well.

Provides fresh air and reduces potential for explosive mixtures in vapor area between floating and fixed roofs. vertical pipe (attached to gauge hatch) extending almost to tank bottom.
5.3.3.1 Fixed Roof Tank with Internal Floating Roof
• Fixed Roof Tank with Internal Floating Roof Tank liquid in the tank and the other end extends a vertical distance of at least 61 centimeters above the liquid surface. If two filling the tank, each cover, access hatch, gauge float well or lid on any opening in the internal floating roof must be bolted or
GAUGING DATA POSE QUESTION ON STABILITY OF REFERENCE GAUGE
Movement of the reference gauge point caused by thermal expansion of the gauging well on floating roof tanks. This can be caused by either oil temperature or ambient temperature.
Floating roof tanks PetroWiki
The tank working capacity is obtained by operating a floating roof tank between the maximum high gauge and recommended low landing position for the specific floating roof tank design. A floating roof should be landed only if the tank is to be removed from service for routine inspection or
Storage Tank Floating Suction Working Animation Video

The Art of Tank Gauging
However, if the level is under P2 there is no differential pressure measurement. This will be the case when the level is only 1.5 m to 2.5 m (6 ft to 8 ft) above the tank bottom. With many tanks, the density in the heel of the tank will be different from the density at higher levels.
PETROLEUM PRODUCT STORAGE TANK SOLUTIONS:
(primary / secondary seal) and between the tank shell and the floating roof edge. The purpose of the internal floating roof is to have a minimal vapor zone above the stored liquid. This system reduces emissions and evaporative losses vapor zone from the fixed roof storage tanks. Our internal floating roof complies with environmental regulations and the latest edition of API 650 Appendix H standard.

US4468975A Gauge well float for floating roof storage
The gauge well is fixed in position within the tank, and as the floating roof of the tank moves up and down with the level of the stock stored therein, it slides along the gauge well. In order to permit accurate sampling of the stock within the tank, the gauge well is provided with slots spaced along its length.
