The GRACO 15U731 is a down tube specifically designed for use with the GRACO Matrix Tank Level Monitor (TLM). It is intended to ensure accurate fluid level measurement in tanks and is a genuine GRACO part. The material is not explicitly specified in available documentation, but it is a critical component for proper TLM operation.

Key Features:

• Down tube
• 15U731
• GRACO Matrix Tank Level Monitor (TLM)
• Ensures accurate tank level measurement when used with GRACO TLM
• Must be used as specified to maintain system accuracy
• Not to be replaced with non-GRACO tubes

Applications:
Used in conjunction with GRACO Matrix Tank Level Monitor (TLM) for monitoring fluid levels in tanks, suitable for various industrial and commercial tank monitoring applications.

Installation Notes:

• Use only the GRACO-supplied down tube (15U731). Substitution with other tubes may result in incorrect TLM operation.
• Do not tilt the TLM more than 2° from vertical during installation
• Mount the TLM and tube at the recommended height above the tank (15 in./30.48 cm)
• Vent the tank separately from the TLM if possible; if not, mounting and venting can be combined for tanks with a single hole
• Ensure the TLM is not mounted close to tank edges or corners
