  • Further Details

    The AlertWerks Ultrasonic Fuel Level Sensor is ideal for use wherever tank levels are critical. For instance, you can use it to monitor fuel levels in remote sites that depend on backup generator power, alerting you if fuel levels fall from use, leaks, or theft. The sensor can be used to monitor other fluids such as oil or gray water, as well. The sensor supports both metal and plastic tanks with tank wall thicknesses up to 6 mm—or larger if a spacer is used and the top limit is adjusted. The sensor has a low profile of less than an inch (only 2 cm) once mounted and has an industry-standard SAE-5 stud mounting pattern with gasket seal and washers.
