Abstract
Provided is a level meter with which a user can easily visually grasp a state of a level of an object from a long distance. The level meter includes a transmission unit that transmits a transmission wave toward an object to one end side in a longitudinal direction, a reception unit that receives a reflected wave of the transmission wave reflected by the object, and a state lamp having a plurality of state LEDs as light sources. A plurality of level ranges is set for the level of the object, and the lighting state of the state lamp changes according to the level range to which the level measured based on the transmission wave and the reflected wave belongs. The state lamp has a transmission window that diffuses the light emitted by the state LED in a direction intersecting the longitudinal direction.
