Features, keys
- Built into a compact resin body, offers excellent corrosion resistance.
- Equipped with various functionsThe LCD display not only displays the level, but also has an echo waveform display and mask function, making on-site adjustments easier.
- Easy to insert and detach cables because waterproof connectors are used.
- Computer output (RS-485C) is equipped as standard.

*1:The nominal measuring distance is determined by the static water level used as a reflecting mirror. It may become shorter with various measuring conditions. (Steam, condensation, waves, etc.)
When a wave-guide is installed, the measuring distance may be made shorter by changing the wave-guide length.
*2: The actual measuring range is determined by each measuring condition.For details, contact to our staff.
