Water level or ga(u)ge height or stage is the elevation of the free surface of a stream, lake or reservoir relative to a specified datum.
Water (chemical formula: H2O) is a transparent fluid which forms the world's streams, lakes, oceans and rain, and is the major constituent of the fluids of organisms. As a chemical compound, a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water is a liquid at standard ambient temperature and pressure, but it often co-exists on Earth with its solid state, ice; and gaseous state, steam (water vapor). It also exists as snow, fog, dew and cloud.
Water covers 71% of the Earth's surface. It is vital for all known forms of life. On Earth, 96.5% of the planet's crust water is found in seas and oceans, 1.7% in groundwater, 1.7% in glaciers and the ice caps of Antarctica and Greenland, a small fraction in other large water bodies, and 0.001% in the air as vapor, clouds (formed of ice and liquid water suspended in air), and precipitation. Only 2.5% of this water is freshwater, and 98.8% of that water is in ice (excepting ice in clouds) and groundwater. Less than 0.3% of all freshwater is in rivers, lakes, and the atmosphere, and an even smaller amount of the Earth's freshwater (0.003%) is contained within biological bodies and manufactured products. A greater quantity of water is found in the earth's interior.
Ladder Logic was the game for the 1998 FIRST Robotics Competition.
The playing field is a carpeted, hexagon-shaped area with an 8 ft (2 m) tall central goal. Three horizontal rail goals extend outward from the center. Each ball placed on the rail goals scores points and each ball in the center doubles the team's score. Around the perimeter of the field are three stations for human players, who work with remote controlled robots on the field to score points. At the start of each match, each team has 3 colored ball at their player station and three balls on the field, and three balls on the rails.
Each robot can weigh up to 130 lb (59 kg), and must start each match small enough to fit inside a 30" x 36" x 48" space. The robots are powered by two Skil 12 volt rechargeable batteries and use motors from Skil, Delco, and Delphi Interior and Lighting, speed controllers from Tekin, pumps from McCord Winn Textron, air cylinders and valves from Numatics, Inc., and a programmable control system supplied by FIRST. Drivers use joysticks from CH Products and switches from Honeywell to remotely control the robots via a radio link which uses RNet wireless modems from Motorola.

A 2 tank gravity drained tank system is controlled by first fitting the dynamic response to a first order plus dead time system and then obtaining initial PID tuning parameters. The controller is implemented in Simulink and simulated to demonstrate acceptable control performance.
So we all know how important it is not to run out of engine coolant water (hopefully!). Also it's not unusual for some engines to use a little bit of water. Modern cars all have a water level warning system, but not a lot of older cars. Here we fit a warning buzzer to an old LANDROVER Freelander 1, but a similar approach could be used with any car with the same parts. Due to the water sloshing around in the tank, it is easy for the float switch that is used to give a false alarm if just wired direct to a buzzer. So three different opproaches are presented for stopping annoying false alarms. The final solution I used on this Freelander was the last little circuit shown at time. 22:25. This circuit, while still being quite simple, filters out false alarms, but it also allows for contin...
Water is the key element of life, but this element that we thought we knew well may have unexpected properties and might play a role greater than we could imagine in our tree of life. That is the belief shared by the advocates of a surprising theory called "water memory". For Prof. Luc Montagnier, water has the hability to reproduce the properties of any substance it once contained. Water would have the hability to retain a memory of the molecules properties. What if alzheimer, parkinson, autism, HIV and even cancer could be treated thanks to this controversial theory?

Does water have a fourth phase, beyond solid, liquid and vapor? University of Washington Bioengineering Professor Gerald Pollack answers this question, and intrigues us to consider the implications of this finding. Not all water is H2O, a radical departure from what you may have learned from textbooks. Pollack received his PhD in biomedical engineering from the University of Pennsylvania in 1968. He then joined the University of Washington faculty and is now professor of Bioengineering. His interests have ranged broadly, from biological motion and cell biology to the interaction of biological surfaces with aqueous solutions. His 1990 book, Muscles and Molecules: Uncovering the Principles of Biological Motion, won an "Excellence Award" from the Society for Technical Communication; his mor...
This video will continue on with the Ultrasonic Level Lab. Now we will take the 4 to 20 mA Analog Signal from the Ultrasonic Sensor that corresponds to the 10 to 50 cm of Liquid Water Level in our tank, and we will input this signal into our Twido PLC. The PLC program will make use of several Compare Statements to turn on sequential Outputs as the level reaches our 0 - 25%, 25 - 50%, 50% - 75%, and 75% to 100% of Tank Level.
(This video includes Introduction and explanation for 14 minutes and project demo afterwards) It's an Arduino project I built to automate water service in my home back in Nepal. I started building it in October 2014. It consists of 3 sub-systems including a handheld device communicating wireless with two other systems via radio transceivers. The system turns the pumps on/off automatically. It monitors water level in the tanks. It also notifies when there is water flowing in a pipe. System includes: Arduino Mega 2560, Arduino Duelimanove, Arduino Uno, NRF2401L radio transceivers, relay switch board, LCD, 4x4 keypad, buzzer, ultrasound sensors HC-SR04 water level float switch, powerbank. It was a wonderful solution to the water service problem, making our lives a lot easier. The ov...
The Delta Works in the Netherlands (Holland) is the largest flood protection project in the world. This project consists of a number of surge barriers, for examples: 1- The Oosterscheldekering is the largest of the 13 ambitious Delta Works series of dams and storm surge barriers and it is the largest surge barrier in the world, 9 kilometres (5.6 mi) long. The dam is based on 65 concrete pillars with 62 steel doors, each 42 metres wide. It is designed to protect the Netherlands from flooding from the North Sea. 2- The Maeslantkering is a storm barrier with two movable arms; when the arms are open the waterway remains an important shipping route however when the arms close a protective storm barrier is formed for the city of Rotterdam. Closing the arms of the barrier is a completely auto...

The story of the American West is deeply rooted in the Colorado River, which delivers fresh water to 30 million people. For years, there has been more Colorado water on paper and in people’s minds than in the river itself. Now climate disruption is making the situation even more troubling. Water levels are so low in Lake Mead that soon they will trigger unprecedented mandatory water cutbacks in Arizona, Nevada and elsewhere. That harsh reality is hard to grok with headlines about the abundance of water in California reservoirs and massive snow levels in the Sierra. How is the Colorado River connected to California’s other water concerns such as the Delta Tunnels and Salton Sea? Join us for a conversation about protecting the water many westerners take for granted and restoring one of the ...
Water quality and agriculture are closely tied. Farmers rely on clean water to keep their fields green, but they also need clean water for their homes, towns and families. Fertilizers and pesticides can move into waterways and build up to dangerous levels. In this Harvest Public Media television special, we'll look at water and agriculture and examines what happens to pristine snow-melt in the Rocky Mountains and how it turns to a toxic 'Dead Zone' in the Gulf of Mexico. We'll see how small towns work to keep their groundwater clean from a legacy of fertilizer use and visit researchers examining frogs and fish exposed to agriculture chemicals. And farmers will demonstrate old and new ways of keeping water clean.
We don't need another water level
We don't need another place to swim
We don't need another world repeating
All the places that we've already been
And now the fish are just too dangerous
And the swimming is much too slow
We don't need another water level
We don't need oh no no no
I've been through the jungle
Many times just today
And I didn't get lost
I've been up to space
With these aliens attacking me
I even fought their boss
But now something smells so fishy
Something ain't right
A new challenge appears
A familiar sight
Oh no, not again
We don't need another water level
We don't need another place to swim
We don't need another world repeating
All the places that we've already been
And now the fish are just too dangerous
And the swimming is much too slow
We don't need another water level
We don't need oh no no no
And now I have to swim again
And get my clothes wet again today
Avoiding killer squid
Seems an evil salmon has torn apart everything
That I already did
And now the baddies are aplenty
And health is rare
So it's back to the surface, back to the surface
Back to the surface to replenish my air
Oh no, not again
We don't need another water level
We don't need another place to swim
We don't need another world repeating
All the places that we've already been
And now the fish are just too dangerous
And the swimming is much too slow
We don't need another water level
We don't need oh no no no
