Simarine Radar Tank Level Sender (STR): One Sensor. Every System. Simarine Precision.

Tank level measurement has always been a compromise.

Different systems, different standards, different inaccuracies, and somehow, none of them quite agree on how full “full” really is.

With the new Simarine Radar Tank Level Sender, we decided to remove the compromise altogether.

👉 Ready to upgrade your tank monitoring? Pre-order now and save 10%.

Built for Digital and Analog World

 

Whether your vessel runs on NMEA 2000, a classic analog setup, or something in between, this sensor fits in effortlessly. And if you don’t need a wired output at all, you can go fully wireless and monitor everything directly from the app via Bluetooth.

– Digital version with full NMEA 2000 compatibility
– Analog outputs supporting the most widely used resistance and voltage standards
– Bluetooth connectivity for direct monitoring via the mobile app — no analog or digital output required
– Compatible with all known marine, RV, and industrial tank monitoring systems.

Now you have just one sensor, but no ecosystem lock-in.

The Constant: Simarine Precision

 

Output formats may differ. Accuracy does not.

At the core of the Radar Tank Level Sender is micro-radar-based, non-contact measurement, a technology chosen not for trend value, but for reliability where other methods fail.

Foam, vapor, condensation, tank shape irregularities? Radar doesn’t care. It measures distance. Precisely.

And because it’s Simarine, that precision isn’t theoretical. It’s practical, repeatable, and designed for real-world conditions.

Smart Calibration, Less Installation Trial and Errors

 

Calibration can be handled directly via the Simarine App using Bluetooth, but you can always configure multiple calibration points for tanks of irregular shapes, for maximum precision.

Install it.
Pair it.
Done.

Installers love it.
Owners love it even more.

Designed for Modern Systems. And Legacy Ones

The Radar Tank Level Sender supports:

– In accordance with the most common analogue output standards
– Multiple analog standards (resistance & voltage)
– Seamless integration with Simarine systems such as PICO
– Future-proof digital communication via NMEA 2000

That makes it ideal for:

– New builds aiming for clean digital architectures
– Retrofits where analog systems still rule
– Displaying tank levels on multiple gauges at the same time, using only one sensor
– Mixed environments where consistency matters more than brand loyalty
– Be it black water, gray water, fuel or fresh water, the content of the tank is no longer a concern.

Low Power, High Confidence

 

Efficient power consumption ensures it fits perfectly into energy-aware systems, marine, RV, or off-grid. You get continuous, accurate readings without unnecessary load on your power system.

Tank data isn’t nice to have.
It is something you totally need because it affects safety, autonomy, planning, and peace of mind.

And when you’re relying on that data,  especially offshore or off-grid, close enough simply isn’t good enough.
