The Tank Level Gauge series - TLG 4DL is designed to display a liquids volume at an accuracy level of min. 1% of the tank using 4 digit ultra-bright LED display. The TLG can be calibrated to any shape/size of the tank. As an additional option an external device (such as buzzer, siren or el.valve) 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 pressure transducer to obtain tank level information. The transducer measures the column of the liquid in the tank above the opening of the elbow and provides a signal that is proportional to the volume.
