A high-precision micro-radar sits on top of the tank and measures the liquid level from outside, so nothing touches the water or fuel and there are no floats or moving parts to stick or wear. It works through flat, rigid plastic or fibreglass (GRP) tank tops up to 10 mm thick and covers tank heights from 150 mm to 2000 mm, with an accuracy of about 2% and a resolution of around 7 mm. Metal tanks can be measured using the Simarine S5 metal tank adapter, which is sold separately.\u003c\/p\u003e\u003cp\u003eInstallation is peel-and-stick. You clean the lid with the supplied alcohol pad, bond the sender near the centre of the tank and connect it to the NMEA 2000 backbone with its M12 5-pin connector. It runs on 8 to 35 V DC and draws only around 14 to 20 mA at 12 V. Once fitted, the STR2 sends tank level as the standard Fluid Level message, PGN 127505, which compatible displays such as Simrad, Lowrance and B\u0026amp;G (NSX, Zeus and NSS families) and Raymarine Axiom can show. Many Garmin models display PGN 127505 for fuel only, so check your display before using it for other fluids.\u003c\/p\u003e\u003cp\u003eSetup is done over Bluetooth in the free Simarine Connect app for iOS and Android. In the app you name the tank, enter its volume and either type in the tank height or let the sender detect it automatically. You can also set the NMEA 2000 tank instance and fluid type, and add up to 100 calibration points for irregular tanks. Firmware updates are delivered through the same app. The STR2 is sealed to IP67, designed and made in Slovenia and covered by a 3-year Simarine warranty. Simarine states that NMEA 2000 certification is pending, and the STR2 is not compatible with the Simarine PICO battery monitor.\u003c\/p\u003e","brand":"Simarine","offers":[{"title":"Default Title","offer_id":58001428185428,"sku":"STR2","price":109.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0941\/9702\/3060\/files\/simarine-str2-radar-tank-level-sender.jpg?v=1793094465","url":"https:\/\/hudsonmarine.co.uk\/products\/simarine-str2-radar-tank-level-sender-nmea-2000","provider":"Hudson Marine Electronics","version":"1.0","type":"link"}
