The GRACO 25V479 Level Sensor Dual Level is a monitoring device designed for use with above ground, stationary lubrication fluid tanks. It is constructed for reliable operation in industrial environments and is intended to provide signals to the Fluid Defender system when a tank is either empty or full, helping to prevent pump cavitation or overfilling. Material is not specified.

Key Features:

• Level Sensor
• Dual Level, 30 ft cable
• Fluid Defender
• Monitors both low (empty) and high (full) tank levels
• Provides warning signals to prevent pump cavitation or overfill
• Can be tied into air control solenoid to shut off air flow to pumps when tank is empty or full
• 30 ft cable allows use in larger storage tanks up to 30 ft in height
• Reliable for stationary tank monitoring

Applications:
Monitoring lubrication fluid tank levels in above ground, stationary tanks for industrial and commercial applications.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance with GRACO equipment.
• Set the level sensor height at least 2–3 inches above the pump inlet to prevent pump runaway conditions
• Tighten the cord grip on the cable to finger tight, plus one-half of a turn to secure the sensor in place
• Connect level sensor wires following instructions in the Fluid Defender manual and local codes
• All accessory circuits are low voltage (less than 48 VDC)
