BG-One Smart Bilge Pump Switch With Oil & Fuel Detector – 12/24V DC is an electronic bilge control device from Blue Guard Innovations that combines automatic pump switching with oil and fuel detection. Installed near the vessel’s bilge pump, it identifies water and oil or fuel, then controls pumping according to the selected operating mode. This smart bilge pump switch helps remove accumulated water while reducing the risk of discharging contaminated bilge liquid overboard in its selective pumping modes. It is designed for integration with compatible 12V or 24V DC bilge pump systems and alarm panels, giving boat owners a practical way to manage water removal and contamination detection together.

Unlike a conventional mechanical float switch, the BG-One uses two integrated solid-state sensors with no moving parts. Its patented detection technology identifies oil and fuel down to 1 mm (0.04 inches), allowing the automatic bilge pump switch to respond to contamination rather than treating every liquid the same way. This distinction is useful in bilges where water may collect alongside leakage from engines, fuel equipment, or hydraulic components. The unit combines a bilge oil detector and bilge fuel detector with pump control, helping operators recognise contamination and address its source. Detected fluids include gasoline, diesel, fossil and synthetic engine oils, and hydraulic fluid.

Three operating modes provide different responses to detected liquid. Mode A, Marina, is the factory default: the pump switches on when water is detected, switches off when oil or fuel is detected, and resumes when only water is detected. Mode B, Marine Sanctuary, also stops pumping when contamination is detected, but keeps the pump off until the alarm and bilge are cleared and the device is power-cycled. Standard Mode, High Seas, operates as a liquid-sensitive bilge pump switch, turning the pump on for any detected liquid and off when no liquid is detected. In this mode, oil or fuel detection does not stop pumping. Choosing the appropriate mode therefore determines how the system handles contaminated bilge liquid.

Integrated Bluetooth connects this Blue Guard bilge pump switch to the BGI Config App on compatible iOS and Android devices. Users can select operating modes, adjust oil detection sensitivity to low, medium, or high, and configure pump timing after water and oil detection. The app also displays input voltage, system temperature, alarm status, and pump switch status. Configuration requires connection within the first minute after powering up the device. For routine care, inspect the sensor area for trapped material, rinse away salt deposits with fresh water, and remove oil or fuel residue as directed in the manufacturer’s manual. Keeping the sensing area clean supports proper operation after contamination has been cleared.

Key Features:

• BG-One Smart Bilge Pump Switch With Oil & Fuel Detector – 12/24V DC combines automatic water detection, oil and fuel sensing, and selectable pump control in one solid-state device.
• Selective pumping: Marina and Marine Sanctuary modes stop the bilge pump when oil or fuel is detected, with different restart conditions.
• Electrical capacity: Supports bilge pump loads up to 20 amps, with a separate alarm output rated at 1 amp maximum.
• Marine construction: IP68-rated, corrosion-resistant ABS plastic housing and mounting bracket; approximately 4.6 inches in diameter × 2.0 inches high without the bracket.
• Installation connections: Five-wire system with 6-foot, 14 AWG marine-grade leads for integration with the vessel’s pump and control wiring.
• Bluetooth adjustment: Configure sensitivity and pump timing through the BGI Config App. CE and ISO 8846 Marine Ignition Protection certified, with testing to ABYC-1500 standards.

Applications / Suitable For:

• BG-One Smart Bilge Pump Switch With Oil & Fuel Detector – 12/24V DC is suitable for compatible boat and yacht bilge systems requiring automatic pumping with oil and fuel detection.
• Marina and mooring use: Factory-default Marina Mode provides water removal with automatic restart once only water is detected.
• Controlled restart applications: Marine Sanctuary Mode keeps pumping disabled after contamination detection until clearing and power cycling are completed.
• Bilge system upgrades: Suitable for replacing mechanical float-switch control where electrical ratings and wiring match. Install the sensor horizontally near the pump for effective oil detection.

FAQs:

Q: What does the BG-One Smart Bilge Pump Switch With Oil & Fuel Detector – 12/24V DC do?
A: It controls a compatible bilge pump automatically and detects oil or fuel. Its response to contamination depends on the selected mode.

Q: Will the pump stop when oil or fuel is detected?
A: Yes, in Marina and Marine Sanctuary modes. High Seas Mode pumps any detected liquid, including oil or fuel.

Q: What pump capacity can it control?
A: The maximum pump load is 20 amps. The separate alarm output supports a maximum load of 1 amp.

Q: How are the settings adjusted?
A: Use Bluetooth and the BGI Config App to select modes, change oil sensitivity, and adjust pump timing.
