Option 3 - Matching displacer output
The tank height (reference gauge height) and the probe length should be set to the same value.
The LRV is the distance from the bottom of the probe to the lower tap. The URV is the LRV plus
the distance to the upper tap. In this example, tank height (reference gauge height) equals the
probe length of 23 in. (584 mm), the LRV is 4 in. (102 mm), and the URV is 18 in. (457 mm).
