Abstract: Provided is an intrinsically safe explosion-proof level meter that can be simplified in design. An intrinsically safe explosion-proof level meter includes a level meter main body and a power supply path to measure a level of an object stored in a container. The level meter main body includes a transmission circuit, a reception circuit, a level determination unit, an operation switch, and a display.
