Emitter Electronics 25

Tank Level Gauge - TLG04ASW is designed to display a liquid ’ s volume at an accuracy level of 1 / 4 of the tank using 4 ultra-bright LEDs . For exsample , when the tank level is 1 / 4 the the LED at 1 / 4 is on , when the tank level is below 1 / 4 the LED at 1 / 4 is flashing . As an additional option an external device ( such as buzzer , siren , valve , PLC , etc ) can be controlled by a two relay outputs or six MFet outputs 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 .
