Overview
The differential-pressure hydrostatic level gauge system consists of a liquid storage tank, differential-pressure hydrostatic level gauges, communicating pipes and other components. The system is composed of several differential-pressure hydrostatic level gauges; the storage tank and the gauges are connected by an air pipe and a liquid pipe. The datum point is placed at a relatively stable base point. When a measuring point rises or falls relative to the datum point, the liquid level at each point changes. From the liquid level change between the datum point and the measuring points, the rise and fall of each measuring point relative to the horizontal base point is calculated.
