Navlink Blue & Sensor - Boat Water Level Monitoring System

Description

KEY FEATURES

A reliable boat water level monitoring system is essential for maintaining safety and protecting your vessel from unexpected leaks or water ingress. This advanced solution uses wireless Bluetooth sensors to continuously monitor critical areas such as the bilge, engine room, and storage compartments, ensuring that even small amounts of water are detected early. By eliminating the need for complex wiring, installation is quick and flexible, making it ideal for both new builds and retrofit applications.

Designed for modern marine environments, the system integrates seamlessly with NMEA 2000 networks, allowing real-time alerts to be displayed directly on compatible onboard screens. When water is detected, the system immediately triggers both a local audible alarm and a digital notification, giving you instant awareness whether you are on deck or monitoring from the helm. This dual alert approach helps prevent minor issues from becoming costly damage.

Compact, battery-powered, and highly responsive, this boat water level monitoring system provides a dependable layer of protection without adding complexity. It is particularly suited for hard-to-reach or previously unmonitored spaces where traditional wired sensors are impractical. With its combination of smart connectivity, early detection capability, and easy installation, it offers a modern and efficient way to safeguard your boat and enjoy greater peace of mind on every journey.

OPERATION

The configuration of NavLink Blue is done through a simple and intuitive web interface, thanks to the simultaneous operation of Bluetooth and Wi-Fi.

This interface allows you to add new sensors and modify certain parameters of connected sensors.

The “Settings” page enables monitoring of NMEA 2000 network parameters, including connected devices, transmitted messages, and exchanged data.

Through the web interface, you can also assign a name to each water level sensor, allowing you to identify exactly which part of your boat has taken on water. The interface also allows you to perform NavLink Blue software updates.

Sales FAQs

How many BT sensors can be connected?

−

This depends on which sensor you are connecting to, but in general NavLink Blue can connect up to 16 BT sensors simultaneously.

This allows you to create a complete onboard monitoring system, including temperature, wind, tank levels, and many other types of data.

Which BT sensors are compatible with NavLink Blue?

−

NavLink Blue is compatible with several Bluetooth Low Energy (BLE) sensors capable of transmitting their data directly to the boat’s NMEA 2000 network. Among the sensors currently supported are:

the environmental sensors RuuviTag and RuuviTag Pro (temperature, humidity, atmospheric pressure)
ultrasonic wind sensors from Calypso Instruments
tank level sensors from Mopeka
the iOS application NMEA Remote

These sensors can be connected directly to NavLink Blue, and their data is then transmitted to the NMEA 2000 network and displayed on compatible chartplotters and multifunction displays.

NavLink Blue is a future-proof and evolving product, with the list of compatible sensors continuously expanding. If you would like to use a specific BT sensor, please contact us by email.

Our team can review its compatibility and potentially add support in future NavLink Blue software updates.

What is the difference between NavLink Blue and an NMEA Wi-Fi server?

−

The NavLink Blue uses Bluetooth Low Energy (BLE) instead of Wi-Fi. This offers:

lower energy consumption
a direct connection with Bluetooth sensors
a new range of compatible devices.

Is the pack compatible with all NMEA 2000 networks?

−

Yes. NAVLink Blue complies with the NMEA 2000 standard and works with all N2K-certified equipment: wind sensors, speed or depth probes, GPS, environmental sensors, etc. It is also compatible with the Raymarine SeaTalkNG standard via an NMEA 2000 to SeaTalkNG connector adapter.

Can NMEAremote app and the RuuviTag sensor scanning function be used simultaneously?

−

No. The NAVLink Blue operates either in continuous data transmission mode to NMEAremote (or other applications) or in scan mode for nearby Bluetooth sensors such as RuuviTags. It is not possible to use both modes simultaneously.

Does NAVLink Blue replace a Wi-Fi router?

−

No. It is designed as an NMEA 2000 ↔ Bluetooth gateway (and Wi-Fi for configuration), but is not intended to replace a WiFi router.

Can NAVLink Blue be customised?

−

Yes. Using the SDK provided, developers can create their own Bluetooth integrations and connect new sensors or systems to the NMEA 2000 network.

Does NAVLink Blue work straight out of the box?

−

Yes. It is immediately operational in Bluetooth mode and can send NMEA 2000 data to the NMEAremote iOS application without advanced configuration.

Does the installation require technical skills?

−

No. Simply connect the NAVLink Blue to the NMEA 2000 backbone.

What is the Bluetooth range of the NAVLink Blue?

−

The range varies depending on the environment. In general, it is 10 to 15 metres. However, please note that steel or carbon fibre hulls can significantly attenuate the signal and require more careful installation.

Is the NavLink Blue compatible with all NMEA 2000 networks?

−

Yes. The NAVLink Blue complies with the NMEA 2000 standard and works with all N2K-certified equipment: wind sensors, speed or depth probes, GPS, environmental sensors, etc. It is also compatible with the Raymarine SeaTalkNG standard via an NMEA 2000 to SeaTalkNG connector adapter.

Using NAVLink Blue with NMEA Remote App

−

NAVLink Blue will not appear in a conventional Bluetooth pairing screen because it supports a specific standard.

Ensure NAVLink Blue is in BT mode.

Then open NMEA Remote on your iPhone or iPad.

Tap Menu, then Settings (by clicking on “NMEA Remote” at the top of the menu).

Navigate to NMEA > Sources > Edit > Add Source.

NAVLink Blue should appear in the list.
