Tank Level Gauge - TLG08 is designed to display a liquids volume at an accuracy level of 1/8 of the tank using 9 ultra-bright LEDs. For example, when the tank level is below 1/4 the LED at 1/8 is flashing, when the tank level is below 1/8 the red LED at 0 turns on. As an additional option an external device (such as buzzer or siren) can be controlled by a relay output pin on the indicator unit.
The indicator is able to communicate with the other displays (Remote Indicators) via the one wire datalink. The unit uses a
0-600mbar (0-8.7PSI) temperature-compensated pressure transducer to obtain tank level information. The transducer measures the coloumn of the liquid in the tank above the opening of the elbow and provides a signal that is proportional to the volume.
