DEF

... a device that measures and records the position of the upper surface of water in a reservoir, channel, stilling well, or natural water body.

CONT

Some water level recorders utilize a float on the surface of the water which is attached to a moveable gear in the recorder. A rise or fall of the water surface causes the float to rise or fall. This rotates the gear and the movement is recorded. Other water level gauges monitor either relative or absolute pressure at a point under the water surface. This pressure measurement can then be converted to height of the water surface. Still other water level recorders monitor the travel time of sound waves generated and received at a point above the water surface. This travel time can then be converted to the height of the water surface.
