Abstract
Combining several capillary tubes in one depth gauge, which measure the depth in different ranges, will allow obtaining a measuring scale close to linear and eliminate the main disadvantage of a capillary depth gauge.
Claims1
A device for measuring depth, comprising a housing with a scale and a measuring element located in the housing along its circumference, characterized in that in order to increase the accuracy of measuring the depth of immersion, the measuring element is made in the form of several capillary channels (tubes) connected at one end to external environment and stoppered on other end, each of which is designed to measure a given range of depths, while the first channel (tube) has two chambers, measuring and absorbing, and all subsequent channels have three chambers, two absorbing and one measuring and the length (volume) of each of the capillary channels (tubes) is calculated based on the required length of the measuring chambers of these channels (tubes).
