King and Rain - Rain gauge - Netflix
A rain gauge (also known as an udometer, pluviometer, or an ombrometer) is an instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation over a set period of time.
King and Rain - Pluviometer of intensities - Netflix
The pluviometer of intensities (or Jardi's pluviometer) is a tool that measures the average intensity of rainfall in a certain interval of time. It was initially designed to record the rainfall regime in Catalonia but eventually spread globally throughout the world.
It employs the principle of feedback ... the incoming water pushes the buoy upwards, making the lower “adjusting conic needle” to let pass the same amount of water that enters into the container, this way ... the needle records on the drum the amount of water flowing through it at every moment—in mm of rainfall per square-meter.
It consists of a rotating drum that rotates at constant speed, this drum drags a graduate sheet of cardboard, which has the time at the abscissa while the y axis indicates the height of rainfall in mm of rain. This height is recorded with a pen that moves vertically, driven by a buoy, marking on the paper the rainfall over the time (the cardboard sheet is usually for one day). While the rain falls, the water collected by the funnel falls into the container and raises the buoy ..., that makes the pen arm raising in the vertical axis marking the cardboard accordingly. If the rainfall does not vary, the water level in the container remains constant, and while the drum rotates, the pen's mark it's more or less a horizontal line, proportional to the amount of water that is falling. When the pen reaches the top edge of the recording paper, it means that the buoy is “up high in the tank” leaving the tip of the conic needle in a way that uncovers the regulating hole (i.e. the maximum flow that the apparatus is able to record). If the rain suddenly decreases, making the container (as it empties) to quickly lower the buoy, that movement corresponds to a steep slope line that can reach the bottom of the recorded cardboard, if it stops raining. The pluviometer of intensities allowed to record the precipitation over the time and the years, particularly in Barcelona (95 years), apart from many other places around the world, such as Hong Kong.
