Traditional mechanical float switches often jam over time, capacitive probes are prone to calibration drift, and ultrasonic sensors frequently struggle with surface foam. By utilising high-precision radar waves, the STR1 measures tank levels from the outside without ever touching the liquid. This makes it an exceptional solution for monitoring fresh water, grey water, black waste water, and fuel tanks.\u003c\/p\u003e\n\u003cp\u003eDesigned to read directly through plastic, fibreglass (GRP), and composite tank walls up to 10mm thick, installation is clean and straightforward. The external peel-and-stick top-mount design means you do not need to drill new holes into your plastic tanks, eliminating the risk of leaks, structural weakening, or hazardous vapour escapes. For metal tanks, the unit can still be utilised by pairing it with the SI-STR03 metal tank adapter (sold separately).\u003c\/p\u003e\n\n\u003ch3\u003eUniversal Analogue Compatibility and Simarine Integration\u003c\/h3\u003e\n\u003cp\u003eEngineered as a versatile drop-in replacement for legacy tank senders, the STR1 supports standard European (0 to 190 Ohm), American (240 to 30 Ohm), and voltage (0 to 5V DC) signal outputs. Uniquely, all three analogue signal outputs operate simultaneously. This allows you to wire the sender to multiple gauges or monitoring systems concurrently without signal interference, alongside native compatibility with Simarine PICO battery and tank monitors.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-invasive external mounting\u003c\/strong\u003e prevents tank leaks and protects the sensor from corrosive fuels, waste build-up, and foul water\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimultaneous triple-output capability\u003c\/strong\u003e supports 0-190 Ohm, 240-30 Ohm, and 0-5V DC gauges at the same time\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide measurement range\u003c\/strong\u003e accurately reads tank depths from 150mm to 2000mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBluetooth connectivity\u003c\/strong\u003e enables effortless setup, auto tank-height detection, and firmware updates via the Simarine Connect app\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide 8V to 35V DC operating range\u003c\/strong\u003e suits both 12V and 24V electrical systems in boats, RVs, and commercial vehicles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP67 sealed enclosure\u003c\/strong\u003e protects internal electronics against dust and water immersion in harsh marine bilges and exposed chassis mounts\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eStreamlined Setup via Bluetooth\u003c\/h3\u003e\n\u003cp\u003eCalibrating traditional tank senders can be a tedious process of manual adjustments and guesswork. The STR1 simplifies commissioning through built-in Bluetooth connectivity. Using the free Simarine Connect app on your smartphone, you can execute automatic tank-height detection, set custom tank parameters, view live tank levels directly on your phone, and perform over-the-air firmware updates. The integrated wiring guide tag on the five-wire cable ensures straightforward, colour-coded integration into your existing 12V or 24V DC wiring harness.\u003c\/p\u003e\n\n\u003ch3\u003eBuilt for Harsh Environments\u003c\/h3\u003e\n\u003cp\u003eManufactured in Slovenia to rigorous quality standards, the STR1 is housed in a durable, IP67-rated enclosure built to withstand the demanding conditions of marine bilges and off-road caravan underbodies. With a low current draw of approximately 14mA to 20mA at 12V, it delivers continuous 1Hz sampling rates with minimal impact on your auxiliary battery bank.\u003c\/p\u003e\n\n\u003ch3\u003eUpgrade Your Tank Monitoring System\u003c\/h3\u003e\n\u003cp\u003eEliminate false readings and high-maintenance mechanical floats from your vessel or recreational vehicle.
