Abstract
The invention discloses an indirect type liquid level measuring device which comprises a first cavity, a second cavity and a third cavity. When the liquid level in an external liquid container to be measured rises, the pressure of the second cavity communicated with the third cavity through an air pipe is increased along with increasing of the pressure of the third cavity, and therefore the liquid level of conductive liquid in the first cavity communicated with the second cavity rises and makes contact with a conductive needle above the liquid level. When the liquid level in the external liquid container to be measured is lowered, the pressure of the second cavity communicated with the third cavity through an air pipe is decreased along with decreasing of the pressure of the third cavity, and therefore the liquid level of the conductive liquid in the first cavity communicated with the second cavity is lowered and makes contact with the conductive needle above the liquid level. By means of the structural design, the liquid level of liquid in the external liquid container to be measured can be indirectly and conveniently measured.
