FIELD OF THE INVENTION
The present invention relates to a water level measuring tool. More particularly, the present invention pertains to a portable tool for measuring water level, that is used to measure the depth of water on a runway for reporting the water level status in Global Reporting Format before take-off or landing of the aircraft for aviation safety reasons, reducing the risk of accidents and ensuring efficient airport operations.
BACKGROUND OF THE INVENTION
Airports play a crucial role in facilitating seamless air transportation, providing essential infrastructure and services for passengers, cargo, and aircraft. Efficient airport operations ensure smooth and timely departures and arrivals, enabling people and goods to reach their destinations safely and on schedule.
Accidents due to water collection on the runway cause significant impacts on travel, logistics, and overall airport functionality. Water on the runway surface reduces the friction between the tires of an aircraft and the runway. This results in decreased braking effectiveness and reduced traction during takeoff and landing, increasing the risk of skidding or hydroplaning. In cold weather conditions, standing water on the runway can freeze, forming patches of ice that pose a significant hazard to aircraft operations. Ice accumulation on the runway surface reduces traction and increases the likelihood of aircraft skidding or sliding during takeoff, landing, or taxiing.
Also, the jet engines are susceptible to ingesting water when operating on wet or flooded runways. This can cause engine surges or flameouts, compromising engine performance and potentially leading to catastrophic engine failure.
For these reasons, airports employ regular runway inspections to mitigate the effects of water accumulation on runways and comply with establishing runway friction coefficient standards.

Described survey line one end is arranged in external conductive casing through incoming line, and the survey line includes the first conducting wire and the second conducting wire, and described first conducting wire one end is electrically connected with the metal shell, and the other end is electrically connected with the suggestion device. Second conducting wire is electrically connected with the conductive probe, and the other end is electrically connected with the suggestion device. Water enters in shell after level detecting device touches water, turns on conductive probe and external conductive casing, and transmitting suggestion device by survey line can prompt in time, so that convenient and accurate real-time testing water level.
US3986110A discloses a device for use in determining the depth of water accumulating on the surface of a pathway, such as an airport runway or the like. A block of electrically insulative material is embedded in a pathway with the top surface of the block being substantially flush with the pathway surface and exposed to atmospheric precipitation. A sensor comprising first and second capacitors, each of which has first and second coplanar spaced apart electrodes, is positioned within the block with the electrodes of the first capacitor positioned adjacent to and inclined with respect to the top surface of the block and with the electrodes of the second capacitor being positioned a substantially greater distance from the top surface of the block whereby an accumulation of water on the surface of the block affects the dielectric, capacitance and conductance of the first capacitor without substantially affecting the dielectric, capacitance and conductance of the second. Time-varying out-of-phase electrical signals are applied to the first electrodes of the capacitors as the input to the sensor. An output circuit commonly connected to the second electrodes of the aforesaid capacitors supplies an electrical output signal relative to electrical ground from the sensor. At least one electrical conductor within the block is connected to electrical ground with a portion thereof exposed to the atmosphere at the top surface of the block. Accumulation of water on the surface of the block affects the capacitance and conductance between the output circuit and electrical ground whereby the amplitude of the electrical output signal of the sensor is a function of the depth of water accumulating on the surface of the pathway.
