Battery-powered level indicator for measuring the liquid level of water tanks such as rainwater, sewage chambers or slurry tanks from a distance of up to 100 m. After touching the button, indication occurs via 10 LEDs in steps of 10 % each (indication 10 - 100 %). The device is earmarked for wall assembly (approx. 120 x 70 x 20 mm) and requires 2 batteries „AA“. Connection is made via terminals inside the device. A normal signal cable (telephone cable, control wire or the like) with at least 11 cores is necessary to connect your water tank with the level indicator (cable is not included). You may also employ cables with less cores, but then it will not be possible to use all indication steps (e.g. with 8 cores only 7 LED indication steps may be used, which is, however, often sufficient).
3 V/DC (2 built-in AA batteries)
max. 10 LEDs and 1 LED for the battery control
