Safiery STAR-Tank Phased Coherent Radar Water Tank Sensor
Litio Store is an official Safiery distributor. We pay the import taxes: the price you see here is the price you pay, with no duties and no customs clearance charges on delivery.
STAR-Tank is Safiery's phased-coherent radar level sensor for fresh, grey and black water tanks: it measures the liquid surface from above, with no float and nothing immersed, and sends level, temperature and battery voltage over Bluetooth to a Victron GX device.
Battery-operated phased-coherent radar water-tank level sensor, Victron/Cerbo compatible.

Key features
- Contactless radar: nothing sits in the liquid
- Plastic or fibreglass tanks: reads through the tank top from a bonded base, no hole needed
- Metal tanks: a hole with an SAE 5-bolt flange is required, as radar cannot see through steel or aluminium
- Internal battery with an expected life of 3-5 years: no wiring
- Bluetooth 5.3 to a Victron GX (Cerbo GX, Ekrano GX); optional kit for MFD displays
How it works
The sensor sits on top of the tank and uses a radar wave to measure the distance to the liquid surface; the first 30mm below the base are a dead band. Every 60 seconds it sends level, temperature and battery voltage over Bluetooth to a Victron GX device running Venus OS (GX units without built-in Bluetooth need a supported USB adapter), and the measuring range and litre calibration are set in the GX Bluetooth sensors menu. From the GX the reading reaches the GX Touch, the VRM portal and, with NMEA 2000 output enabled, compatible chartplotters; marine MFDs need the STAR-Tank to MFD interface kit. The sensor does not pair directly with a phone: on a phone you read the level through VRM.
