Rain gauge for measuring liquid precipitation over a set period of time; Wind sock for measuring general wind speed and wind direction; Wind vane (also called a weather vane or a weathercock) for showing the wind direction; Present Weather/Precipitation Identification Sensor for identifying falling precipitation; Disdrometer for measuring drop ...
For example, if one rotation of the hand is 10 gallons, the sweep hand is on 7, and the wheel display shows 123456 plus a fixed zero, the actual total usage would be 1,234,567 gallons. In the United States most utilities bill only to the nearest 100 or 1,000 gallons (10 to 100 ft 3 , 1 to 10 m 3 ), and often only read the leftmost 4 or 5 ...
Hardened and ground plug gauge Replaceable thread and plug gauges. These gauges are referred to as plug gauges; they are used in the manner of a plug.They are generally assembled from standard parts, where the gauge portion is interchangeable with other gauge pieces (obtained from a set of pin type gauge blocks) and a body that uses the collet principle to hold the gauges firmly.
Short-radius (or regular) 45° elbow (copper sweat) Long-radius (or sweep) 90° elbow (copper sweat) An elbow is installed between two lengths of pipe (or tubing) to allow a change of direction, usually a 90° or 45° angle; 22.5° elbows are also available. The ends may be machined for butt welding, threaded (usually female), or socketed. When ...

Gauge blocks (also known as gage blocks, Johansson gauges, slip gauges, or Jo blocks) are a system for producing precision lengths. The individual gauge block is a metal or ceramic block that has been precision ground and lapped to a specific thickness. Gauge blocks come in sets of blocks with a range of standard lengths.
There are also some extreme narrow-gauge railways listed. See: Distinction between a ridable miniature railway and a minimum-gauge railway for clarification. Model railway gauges are covered in rail transport modelling scales. Train with model Southern Railway Schools class Triple-gauge pointwork (3 + 1 ⁄ 2 in, 5 in, and 7 + 1 ⁄ 4 in) on ...
