It surface-mounts to the outside of the tank with the included 3M adhesive backing and measures into the space above the fluid, giving you accurate, drift-free readings without the mechanical wear points that plague traditional float senders.\u003c\/p\u003e\n\u003cp\u003eDesigned and built at Garden Bay Maker Space for fuel, fresh water, and waste tanks, with output options that connect to virtually any system — from a modern NMEA 2000 network to a vintage analogue gauge.\u003c\/p\u003e\n\u003ch3\u003eWhy radar?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNothing inside the tank.\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eThe sensor mounts externally and reads through into the airspace above your fluid — no float arms, no corrosion, no moving parts to fail.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1mm resolution.\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIndustrial-grade sensing tells you exactly how much fuel or water you have left.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccurate from 150mm to 2000mm.\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eA wide measuring range covers everything from a small day-tank to a large bulk tank.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eUnderstanding the 150mm deadzone\u003c\/h3\u003e\n\u003cp\u003eRadar needs a minimum distance to resolve a clean return. Within 150mm of the sensor face there isn't enough room for the pulse to reflect back reliably, so this band is treated as a deadzone. In practice, once the fluid surface rises to within 150mm of the sensor, the tank simply reports\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e100% \/ full\u003c\/strong\u003e.
