Multi Tank Monitoring Gauge | KUS KY89900

KUS CP7-B Multi-Tank Monitoring Gauge Panel | KY89900 | 7-Tank Toggle | IP67 | 12V/24V

The KUS CP7-B (KY89900) is a multi-tank level monitoring gauge panel that consolidates up to seven tank level readings into a single 4" × 6-1/8" dashboard instrument. A single button toggles between all monitored tanks, eliminating the need for multiple individual gauges and preserving dashboard space on vessels with complex tank configurations — fuel, fresh water, holding, gray water, ballast, or any combination of standard 240–33Ω sender tanks. Rated IP67 for waterproof and dustproof protection. Compatible with 12V and 24V DC electrical systems.

Additional Information

How the CP7-B Works — Seven Tanks, One Gauge:

The CP7-B replaces up to seven individual tank level gauges with a single panel-mount instrument. Each press of the selector button cycles to the next tank in the sequence, displaying its current level on the gauge face from Empty to Full. This is particularly valuable on larger vessels where dashboard or helm space is limited and multiple tanks — port and starboard fuel, fresh water, holding, gray water, or ballast — would otherwise require multiple gauge cutouts and individual wiring runs.

Sender Compatibility — 240–33Ω:

The CP7-B is compatible with the standard 240–33Ω sender resistance range used by the majority of marine tank level senders from Wema, KUS, Faria, Rochester, and other common marine sender manufacturers. Verify your tank sender resistance specification before wiring. Do not use with senders outside this resistance range — non-standard senders will produce inaccurate readings.

IP67 Protection — Waterproof for Marine Helm Environments:

IP67 certification means the CP7-B is rated for complete dust protection and temporary immersion in water up to 1 meter for up to 30 minutes. This is the appropriate protection rating for exposed helm stations, open flybridge installations, and other marine environments subject to spray and wash-down.

12V/24V Dual-Voltage Compatibility:

The CP7-B operates on both 12V and 24V DC electrical systems without modification, making it suitable for the full range of recreational and light commercial marine vessels regardless of DC bus voltage.

Installation Notes:

• Panel cutout dimensions: confirm against KUS CP7-B installation documentation for the exact cutout size before cutting
• Wiring: each of the up to seven tank senders requires a dedicated signal wire run to the CP7-B; plan wiring harness routing before installation
• Sender resistance: verify all connected senders are within the 240–33Ω range; mixing sender resistance standards on the same panel will produce inconsistent readings
• Grounding: a clean, dedicated ground connection is required for accurate sender readings; poor grounds are the most common cause of erratic level gauge behavior

Frequently Asked Questions

1. Can the CP7-B monitor different tank types — fuel and water on the same panel?
Yes — the CP7-B monitors any tank equipped with a compatible 240–33Ω level sender, regardless of tank contents. You can monitor fuel, fresh water, holding, gray water, ballast, or any combination across up to seven tanks from a single gauge panel. Label each tank position clearly during installation so the button-toggle sequence is intuitive to the operator.

2. What sender resistance range does the CP7-B support?
The CP7-B uses the standard marine 240–33Ω sender range. Verify your tank senders match this specification before purchasing. If your vessel uses a different sender resistance standard (e.g., 0–180Ω or 10–180Ω), the CP7-B will not produce accurate readings without compatible senders.

3. Does the CP7-B work on a 24V system?
Yes — the CP7-B is dual-voltage and operates on both 12V and 24V DC systems without any modification or additional hardware.

4. What is the panel cutout size for installation?
The CP7-B panel body is 4 in. H × 6-1/8 in. W. Refer to the KUS CP7-B installation documentation for the exact cutout dimensions required — confirm before cutting your dash panel.

5. Is the CP7-B rated for outdoor or flybridge installations?
Yes — the IP67 rating confirms the CP7-B is suitable for exposed helm and flybridge installations subject to spray, rain, and wash-down. IP67 covers complete dust protection and temporary water immersion to 1 meter for up to 30 minutes.
