Overview
Making use of the principle of communicating vessels and of level surfaces, the liquid surfaces of several magnetostrictive level gauges connected together by communicating pipes always lie in the same horizontal plane. When settlement occurs at a certain point, the liquid level height of the equipment at each point changes. From the change in liquid level height at each monitoring point, the relative settlement and differential settlement of each hydrostatic level gauge can be calculated. The liquid height is measured by a magnetostrictive sensor, which calculates the liquid level height from the time difference between the pulse emitted by the electrical excitation and the reflected pulse.
