This VOTRONIC tank gauge was designed for accurate level measurement and can be used for all tank materials and tank sizes. The fill level of the tank is displayed as a clear light bar with 10 LEDs in three colors, which allows the exact detection of the tank level at a glance. The display is even stepless, as intermediate levels are displayed with variable brightness, thus also making tendencies immediately recognizable. When filling and emptying the tanks, the continuously rising or falling display provides a direct image of the current fill level. At the push of a button, the display can be switched on and off, or switches off again automatically after approx. 10 minutes. Small front panel dimensions and the particularly low installation depth of only 15 mm allow mounting in almost any location. Can be used e.g. with tank probe 801201 (for tank heights 15-35 cm) or 801203 (for tank heights 20-50 cm)
