FIELD: measurement equipment.SUBSTANCE: as a facility to measure length, a flexible metering wire is used, onto which a group of main markers is applied, indicating ends of metre intervals of the metering wire, and also a group of additional markers visually distinct from main markers, distance of which from ends of metre intervals is proportionate to the order number of the nearest metre interval of the metering wire preceding this additional marker.EFFECT: development of compact devices of length measurement with small dimensions making it possible to perform measurements up to several dozens of metres. |
