The LEVELIS LPU-420-W programmable display unit
The LEVELIS LPU-420-W programmable display unit is used to visualize physical quantities such as fluid level or flow rate, the magnitudes of which are expressed by means of a signal current 0/4 to 20mA. The data are displayed in linear, quadratic, square-root or other user-defined modes. The display unit is designed to be hung on a wall. The unit parameters can be set by buttons on the front side or by means of an LRC-1 remote IR control box.
