Product details

The SIMARINE Radar Tank Transmitter STR2 provides high-precision level measurements for plastic tanks using the latest radar technology. Developed for use in modern ship systems, it delivers reliable values - regardless of the tank shape, fluid type or movements of the boat. This makes it ideal for fuel, fresh water, grey water and other on-board tank applications.

With a measuring range of 150 mm to 2000 mm, the STR2 ensures exceptional accuracy and stability, even in demanding conditions where conventional float sensors reach their limits. The non-contact radar measurement technology prevents mechanical wear and ensures a particularly long service life with minimal maintenance. Thanks to automatic calibration, the tank sensor is immediately ready for use.

For maximum compatibility, the STR2 outputs the measured values in NMEA2000 format, making the data available to any compatible display device in your network. Thanks to the integrated Bluetooth interface, users can easily configure the sensor and retrieve real-time level data via their smartphone.

The STR2 is a versatile, future-proof tank level sensor that can be seamlessly integrated into NMEA2000 networks.

Easy installation
Measuring the black water tank was easy. Accuracy needs to be confirmed with use. Connected to my Cerbo GX – the phone app is very useful. Calibration is extremely simple.
Very satisfied!
This fuel level sensor is simply attached to the top of the tank and measures the fill level using radar. The incredibly easy installation is a major plus, as no drilling or installation is required. All that's needed is a connection to the NMEA2000 backbone. The connection cable is approximately 1 meter long.

The sensor is calibrated via Bluetooth using a smartphone app. You can either enter the tank height and maximum fill level, or define any number of individual calibration points. This allows you to use even tanks with complex geometries.

Good things come to those who wait!
Not only is it the most affordable radar fuel level sensor on the market, it's also by far the easiest to install and configure. I have two other sensors from two different manufacturers installed on my boat, so I think I can make that statement.

by Alfred W. Flag of Germany 5/6/2026 Verified purchase Variant: 34752
Received a great product after a long wait.
When the part was finally available and arrived quickly, unfortunately without an adhesive pad (which wasn't a big problem), I was rewarded with a sensor that is very easy to install and calibrate via the app, even though the tank is quite oddly shaped.

I use the sensor via the app, so I don't need to run any cables! It's powered by the water pump.

Everything's great!
