A tuning fork density meter and different reasons

Generally we in using tuning fork density meter readings, is below the small. Because when it is immersed in different liquid, the volume will change, density meter at the bottom of the iron ore or lead is used to adhere to the balance, density meter according to the change of gravity and buoyancy balance will attack floating or sinking. A function of density meter can only float, and buoyancy force pushing upwards to force the force down slightly larger proportion. But on balance, the range of gravity is equal to buoyancy. Attack due to the volume of a densitometer did not change it into boiling water at the same volume. However, because it contains more water then, leading to more. When gravity is greater than the buoyancy, densimeter will sink. Density meter weight is less than the same volume of water gravity, so densimeter will float from scratch. The basic principle of tuning fork density gauge measuring: measure degree of photographic materials after the exposure and development of black namely blackness. In plate making, the silver bromide on the sensitive material, by the light effect, enhancement after reduction into metallic silver, constitutes a certain opacity. Big black degree, high density; Black degree of small, low density. Meter with a filter, but also can measure colorful colors of the original density. Its measuring principle and the basic principle. In general, the density meter is according to the change of gravity and buoyancy balance rise or sink. A function of density meter can only float, and buoyancy force pushing upwards to force the force down slightly larger proportion. But on balance, the range of gravity is equal to buoyancy. Due to the density meter without volume change, a tuning fork it boiled water at the same volume. However, because it contains more water and become heavier. When gravity is greater than the buoyancy, densimeter will sink. Density meter weight is less than the same volume of water gravity, so the density meter from the float. Density meter reading is below the small, when it is immersed in different liquid, the volume change in several attacks, density meter at the bottom of the iron ore or lead is used to adhere to the balance.
