yes. it pulls it downward, not letting it float free.
It tends to float the submerged object on the surface of that medium.
No. A ship going through a lock gets raised or lowered several meters, without any effect on its ability to float.
The dinosaurs knew that they could float, but the individual credited with quantifying the effect is Archimedes.
To read a rotameter, look at the position of the float inside the tube. The flow rate is indicated on the scale where the float is positioned. The number on the scale closest to the center of the float is the flow rate being measured.
The float in rotameter is lifted by the liquid. Rotameter is calibrated for particular liquid or gas with its exact density. if we mount it horizontally float will not come to its original place.
so that there is a linear relationship between the flow rate and position in the float within the tube.
A Rotameter is a device that measures the flow rate of liquid or gas in a closed tube. It is occasionally misspelled as "rotometer." It belongs to a class of meters called variable area meters, which measure flow rate by allowing the cross-sectional area the fluid travels through to vary, causing some measurable effect.

Probably swim bladder disease. Dirty water, stress, over feeding (leading to constipation), and temp fluctuations will cause this.
A rotameter is a type of device that is used to measure the flow rate that a liquid or gas will produce inside a closed tube. The fluid will move in a random direction depending on how it is turned due to gravity.
