The GRACO 25V477 Level Sensor Low Level is a monitoring device designed for use with above ground, stationary lubrication fluid tanks. It is constructed for industrial environments and is intended to detect when a tank becomes empty, providing a signal to the Fluid Defender system to warn of potential pump cavitation. The sensor can be tied into an air control solenoid to shut off air flow to pumps when an empty tank is detected.

Key Features:

• Level Sensor
• 30 ft cable length
• Industrial-grade, designed for above ground, stationary tanks
• Fluid Defender
• Detects empty tank condition
• Provides signal to Fluid Defender system
• Can be tied into air control solenoid for automatic shut-off
• 30 ft cable allows use in large storage tanks up to 30 ft in height
• Helps prevent pump cavitation by warning of low fluid levels

Applications:
Monitoring lubrication fluid tank levels in above ground, stationary tanks; used in industrial and maintenance environments to prevent pump damage due to cavitation.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance with GRACO equipment.
• Install the sensor at the appropriate low level position within the tank
• Ensure proper connection to the Fluid Defender system
• Connect to air control solenoid if automatic shut-off is desired
• Follow all safety and operational guidelines in the equipment manual
• Regularly inspect the sensor and cable for damage or wear; ensure connections remain secure and clean.
