buoy

The higher the liquid level measured by a float level gauge, the greater the buoyant force acting on the float (). Why is the answer that it remains unchanged? ?
I’m not sure what you exactly mean. I think that when the level of the fluid in the float is high, the buoyant force is greater – so how could it remain unchanged?
The float level gauge is a constant buoyancy type level gauge, with the three forces in balance
Reply 1# zqw688: The float is of the variable buoyancy type
Reply to 4# zqw688: Oh, right, right, I got it wrong – the float has a constant buoyant force, 3q
The answer is wrong; sometimes one can’t rely entirely on the answer – understanding the principle is what’s most important.
Reply to 1# zqw688: The buoy has a variable buoyancy; it does not change itself as the liquid level rises or falls.
The buoyancy exerted on the float is constant, and the liquid level measured corresponds to the height of the float; if a different liquid level is required, the only option is to change the diameter of the float.
As the liquid level rises, the buoyant force acting on a float level gauge changes; therefore, the idea that this force remains constant is definitely incorrect. It is a ball-type level gauge whose buoyant force stays the same regardless of whether the liquid level rises or falls.
