Tank Level Gauge - TLG20D is designed to display a liquids volume to 5% tank level accuracy with a 7 segment ultra-bright LED display. When the tank level is below 25% the display fl ashes and when the tank level is below 10% the relay output is turned on (optional).The indicator is able to communicate with other displays (remote indicators) over the one wire datalink.
The unit uses a 0-600 mbar (0-8.7 PSI) temperature compensated pressure transducer to obtain tank level information. The transducer measures the column of liquid in the tank above the opening of the elbow and provides a signal that is proportional to the volume.
