A water level device showing both ends at the same height. A water level (Greek: Aλφαδολάστιχο or (υδροστάθμη) [Alfadolasticho]) is a siphon utilizing two or more parts of the liquid water surface to establish a local horizontal line or plane of reference.
Hydrostatic pressure level sensors are submersible or externally mounted pressure sensors suitable for measuring the level of corrosive liquids in deep tanks or water in reservoirs. Typically, fluid level is determined by the pressure at the bottom of the fluid containment (tank or reservoir); the pressure at the bottom, adjusted for the ...
Tarmacadam is a concrete road surfacing material made by combining tar and macadam (crushed stone and sand), patented by Welsh inventor Edgar Purnell Hooley in 1902. It is a more durable and dust-free enhancement of simple compacted stone macadam surfaces invented by Scottish engineer John Loudon McAdam in the early 19th century.
A stream gauge, streamgage or stream gauging station is a location used by hydrologists or environmental scientists to monitor and test terrestrial bodies of water. Hydrometric measurements of water level surface elevation (" stage ") and/or volumetric discharge (flow) are generally taken and observations of biota and water quality may also be ...
The apron at airports is sometimes informally called the tarmac, [6] even though most of these areas are paved with concrete, not tarmac. [9] Specific materials used include asphalt concrete (which itself is often inexactly called "tarmac", adding to the confusion), porous friction course, and Portland cement concrete. [10]
Tarmac is sometimes incorrectly used, mostly by news media, as a term for any paved surface of an airport regardless of material, including the Airport apron;
Water and other fluids. Adequate fluid consumption is one of the most important dietary components to help avoid constipation. Water makes it easier for food to pass through the gastrointestinal ...
This is the most commonly used measurement system for measuring water supply in houses. The fluid, most commonly water, enters in one side of the meter and strikes the nutating disk, which is eccentrically mounted. The disk must then "wobble" or nutate about the vertical axis, since the bottom and the top of the disk remain in contact with the ...
