Float liquid level gauge principle and installation considerations

Float liquid level gauge is a kind of commonly used liquid level measuring instrument, the main use of zhongheng buoyancy principle of work, material level meter is a commonly used product type they belong to. The principle of float liquid level gauge is what? Today engineering mainly introduce float liquid level gauge principle and installation considerations, hope can help users better application products.

float liquid level gauge principle

in the gravitational field, due to fluid in the object and the surrounding fluid density difference under the vertical force is buoyancy.

in the overall density is lower than the liquid in the liquid density of an object will float in the liquid surface, the object can be called a float. Under the condition of same float (by the buoyancy of the constant Constant buoyancy) 。

when the float is an upward force is less than its weight or by a less than equal to its own volume of fluid force downward, the weight of the float will float on the characteristics of the liquid surface will not be changed.

in the stable state float by buoyancy is constant.

vertical change in liquid surface, the float's vertical position under the action of a constant buoyancy will change with liquid surface position synchronization.

through physical means, such as all kinds of mechanical, electromagnetic and optical will float in the vertical position, in the form of a person can directly read out of facilities, is to float liquid level gauge.

float liquid level gauge installation note

1, the liquid level gauge must be vertical installation, to ensure the float freely up and down in the main tube components.

2, level gauge around the body does not allow a magnetizer is close to or directly affect the level to work properly.

3, level gauge installation has been completed, need to use magnets for correction of double column guide once make red below zero, zero or more showed white.

4, level gauge when put into operation, should open the first guide tube valve for liquid medium under smoothly into the main pipe, avoid the liquid medium with a floating ball component grew rapidly, and cause turn column turn failure and disorderly. If produce this phenomenon after being smooth surface available magnetic steel to correction.

5, because in the process of transportation in order not to make the floating ball component is damaged, so the factory before remove float component level gauge body tube, after being liquid level meter installed, open the blowdown flange, then float components to reload the main tube, pay attention to the floating ball component is heavy on the upside, cannot flip. If the factory has to float components installed in the main tube, renowned in the process of transportation in order to ensure floating ball component is damaged, we use soft card will float component fixed in the main tube, as long as the soft card out when you install.

6, according to media, can find open drain flange cleaning regularly main precipitation tube material.
