Abstract: Provided is a level meter with which a user can easily visually grasp a state of a level of an object to be measured. The level meter includes a sensor unit, a housing, and a display unit. The sensor unit is disposed on one end side along the measurement axis and measures a level along the measurement axis. The housing is disposed on the other end side different from the one end side of the measurement axis. The display unit is provided in the housing, and displays the level measured by the sensor unit with respect to the color graph together with the color graph having a plurality of level ranges color-coded with different colors.

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. The transmission circuit transmits the measurement signal. The level determination unit determines the level based on the measurement signal received by the reception circuit and the information on the container. The display displays the determined level. The power supply path has an intrinsically safe explosion-proof barrier that prevents the level meter main body from becoming an ignition source, and a pressure-resistant explosion-proof box that accommodates the intrinsically safe explosion-proof barrier.
