Liquid flow measurement in open channels — Rotating element current-meters
Specifies the operational requirements, construction, calibration, and maintenance of rotating element devices for the measurement of flow velocities in open channels. Does not define the form of the signal produced by the equipment or the signal receiving equipment. Cancels and replaces the second edition (ISO 2537 : 1985), of which it constitutes a technical revision.
ISO system of limits and fits — Part 2: Tables of standard tolerance grades and limit deviations for...
This part gives of the limit deviations for commonly used tolerance classes calculated from the information given in ISO 286-1. It covers values for the upper and the lower deviations which are illustrated by a figure. It tabulates numerical values for basic sizes from 3 mm up to and including 3150 mm. An annex gives a graphical review of tolerance zones.
