Its compact 7-inch (180 mm) length and doughnut-style float reduce moving-part wear, while a wide operating temperature range and straightforward mounting make it practical for boats, generators, and a variety of vehicles.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the OXCANO sender measure fuel level?\u003c\/h3\u003e\n\u003cp\u003eThe unit uses a rotating arm with a sealed doughnut float that activates reed switches to change electrical resistance as fuel level shifts. That resistance moves linearly between 240 ohms (empty) and 33 ohms (full), creating a simple, widely accepted output for analog and many digital gauges.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e240–33 ohm output range for standard gauge compatibility\u003c\/li\u003e\n  \u003cli\u003eDoughnut float with reed-switch operation reduces mechanical wear\u003c\/li\u003e\n  \u003cli\u003e10 mm resolution for responsive level updates\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIs this sending unit suited for marine conditions and other heavy-duty uses?\u003c\/h3\u003e\n\u003cp\u003eYes — the OXCANO sender was built to tolerate harsh environments.
