GW-Y3 Type Fuel Tank Oil Level Monitoring InstrumentDetailed product description：

One Introduction
The GW-Y3 fuel tank oil level monitor can be used in conjunction with the YW-01 displacement sensor. It can provide excitation power for sensors, with 4-20mA current output and RS485 (RS232) interface, and can be connected to computers and other devices. The monitor adopts a 160 × 80 × 215 (mm) universal case, LED digital display, PVC color facial mask and light touch keys. It has beautiful appearance, reasonable structure, simple installation, stable performance and reliable quality.

II Main functions
1. Display function
The measured fuel level, I value alarm, and II value alarm set values of the fuel tank can be displayed separately on the LED digital tube, with a 4-digit digital tube display and the first digit being the symbol bit.
2. Alarm function
There are two levels of alarms, and users can set the alarm value according to their needs. When the oil level in the tank exceeds the alarm set value, the corresponding alarm indicator light on the front panel will light up, and the monitoring instrument will output a switch signal on the rear panel to protect the controlled equipment.
3. Output interface
Equipped with 4-20mA current output, it can be connected to computers, DCS, PLC and other equipment.
