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!

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.

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.

Product details

With multiple output signals and integrated Bluetooth connectivity, the STR1 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 STR1 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.

For maximum compatibility, the STR1 outputs multiple signals simultaneously:
  • 0–180 Ω resistance
  • 240–30 Ω resistance
  • 0–5 V analogue signal
  • Bluetooth via the SIMARINE app
With the integrated Bluetooth interface, users can conveniently configure the sensor and access real-time level data via their smartphone.

The STR1 is a versatile, future-proof tank level sensor that seamlessly integrates into SIMARINE systems as well as numerous third-party devices.

Unfortunately, the device is useless.
I ordered and installed two devices! One for my dirty water tank on the boat and one for my fresh water tank! I connected the cables to my Victron Cerbo GX and am using resistance measurement. Unfortunately, despite calibration, the readings are almost never accurate!

The tank is full, but it only shows 30%. An hour later, it shows 70%, then after some time, it shows a different reading again, even though nothing is being used and the boat isn't moving! The technology is completely failing! I can't recommend this device! It's a shame; it would be a great solution if it worked! P.S. The display on the app is also erratic, always showing different values!
