Digital indicator I-4 is designed for indicating the actual level in the fuel tank and can be used as summing unit which enables you to know the current volume of fuel in the tank.

Main features:
- Opportunity to connect up to 4 sensors together;
- Summing up the values not only in the form of digits on the screen, but as a frequency output signal;
- Reliable protection from polarity reversal;
- Easily stands voltage surges up to 120 V;
- Fixing and assembly takes only20 minutes
