* 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.
