Marine Tank Monitoring Systems, Sensors & Bilge Alarms

This collection of marine monitoring systems provides precise, real‑time visibility into tank levels, bilge conditions, and onboard fluid management. Featuring industry‑leading brands such as Raritan, Mopeka, Johnson Pump, and Victron Energy, these systems support a wide range of applications including freshwater, grey water, black water, fuel, LPG, and non‑pressurized fluid tanks.

The Raritan TankAssure lineup offers complete monitoring kits, sensor modules, and NMEA2000 adapters for seamless integration with modern marine electronics. Mopeka Pro Check sensors provide wireless BLE and LTE monitoring for LPG, water, and multi‑liquid tanks, with options for bottom‑up, top‑down, and poly tank configurations. For high‑water safety, Johnson Pump Bilge Alert alarms deliver reliable 12V monitoring with sensor‑based activation.

For advanced multi‑tank installations, the Victron GX Tank 140 supports 4–20 mA and 1–10V sensors, enabling precise monitoring of up to four tanks through the Victron ecosystem.

Whether upgrading a single tank or building a complete vessel monitoring network, these systems deliver accuracy, reliability, and compatibility for boats, yachts, and commercial vessels.

FAQs

1. What type of marine monitoring system do I need for my boat?

Choose based on the fluids you need to monitor. Mopeka is ideal for LPG and water tanks, Raritan TankAssure works well for waste and freshwater systems, and Victron GX Tank 140 is best for multi‑tank advanced monitoring.

2. Are these monitoring systems compatible with NMEA2000 networks?

Yes — products like Raritan TankAssure NMEA2000 adapters and Victron GX Tank 140 integrate directly with NMEA2000 and modern chartplotters.

3. What is the difference between bottom‑up and top‑down tank sensors?

Bottom‑up sensors measure fluid levels from the base of the tank, while top‑down sensors mount above the fluid and are ideal for non‑pressurized tanks or installations where bottom access is limited.
