*1 These values were measured at the position of 100 mm 3.94" or less from the wall of a metal tank. Contact KEYENCE for the case of a plastic tank.
*2 These values were measured under the following conditions.
Medium: Water, Tank material: Metal, Linearity range: Between 6 cm 2.36" from the top and 1 cm 0.39" from the bottom, Average time: 4 s
*3 For the sanitary / plastic types, the undetectable area from the bottom end varies depending on the length of the probe.
