LED-Equipped Liquid Level Gauge "Light Graph"

Main points of the mechanism

[1] Independent indication system (Stand alone type)

• The device consists of a single line of LEDs and a direct ON/OFF mechanism operated by the approach of a small magnet.
• A float (bearing the magnet) moves vertically along the line of LEDs.
• The LEDs change from OFF to ON or from ON to OFF in the order that the float passes them.
• The float’s position is indicated by the lighting condition of the LEDs.

[2] External indication system

• A sensor detects the movement of the float and sends a signal to a control unit.
• The liquid level can be confirmed even from a remote location using a PC.
• The lighting pattern of the LEDs indicating the liquid level can be set in advance.
• The system is capable of self-diagnosis in the event of a malfunction, failure, etc.
• The gap between the float and the liquid surface can be adjusted by means of the liquid surface specific gravity
