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.

Product details

With multiple output signals and integrated Bluetooth connectivity, the STR2 offers versatile system integration and continuous, dependable level monitoring. Developed for use in modern ship systems, it provides reliable values—regardless of tank shape, liquid type, or boat movements. This makes it ideal for fuel, fresh water, gray water, and other onboard tank applications.

With a measurement range from 150 mm to 2000 mm, the STR2 delivers exceptional accuracy and stability—even under demanding conditions where conventional float sensors reach their limits. The contactless radar measurement technology eliminates mechanical wear, ensuring an exceptionally long service life with minimal maintenance requirements. Automatic calibration allows the tank sensor to be ready for immediate use.

To ensure maximum compatibility, the STR2 outputs the measured values in NMEA2000 format, making the data available to any compatible display device on your network. With the integrated Bluetooth interface, users can conveniently configure the sensor and access real-time level data via their smartphone.

The STR2 is a versatile, future-proof fuel level sensor that integrates seamlessly 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.
