Description
Technical Field
The utility model relates to the technical field of measuring devices, in particular to a floating ball liquid level measuring device.
Background
The floating ball liquid level meter is a liquid level monitoring instrument widely applied to industrial production, and monitors the liquid level through the buoyancy principle.
The working principle of the floating ball liquid level meter is based on the buoyancy principle. When the liquid level changes, the metal ball body floating on the liquid level of the floating ball rises or sinks correspondingly along with the rise and fall of the liquid level. The up-and-down motion of the sphere is converted into linear displacement of the gauge outfit by driving the converter to rotate through the mechanical driver. By calibrating the displacement with the height of the housing of the float gauge, an accurate level reading can be obtained. Therefore, the position of the floating ball is controlled, and the corresponding liquid level monitoring instrument reads the value of the liquid level height.
The working principle of the floating ball liquid level meter is seemingly simple, but errors are easy to occur in actual operation. First, the density variation of the liquid affects the operation of the float ball, resulting in errors. The method for solving the problem is to select corresponding floating balls according to different densities of the liquid. Secondly, because the mass of the floating ball materials is not necessarily the same and the density is also different, the weight of the floating ball needs to be checked to ensure that the mass is consistent. In addition, the movement of the float is also affected by bubbles, particles and dirt in the liquid. The current approach to this error is as follows: in order to reduce the occurrence of errors, the equipment needs to be checked and maintained regularly, and the floating ball and the inner container of the liquid level meter are cleaned to ensure smooth operation, but the existing floating ball liquid level meter is detached.
It has been investigated that errors are very common due to unstable installation between the liquid container and the gauge, differences in accuracy, etc. Proper installation means that too steep and irregular containers or pipes should be avoided when installing the level meter, as this would lead to instability of the float, thus creating a deviation.
