LIQUID LEVEL GAUGE AND TRANSMISSION DEVICE USED IN LIQUID LEVEL GAUGE

摘要

A liquid level gauge is provided with a displacer (1) or a balancer (18). The displacer (1) or balancer (18) is attached to the leading end of a length measurement cable (9) subjected to tension. All or a portion of the displacer (1) or balancer (18) is positioned above a liquid level. The position of the liquid level is measured through the addition of a measured value of the length-measurement-cable length (second distance) (7) from a measurement reference point height (10) to the displacer (1) or balancer (18) and a measured value measured by a liquid level meter (2) positioned near the liquid level of the distance (first distance) (8) from the displacer (1) or balancer (18) to a liquid level to be measured (5).
