Autocal Fuel Level Senders

Livorsi Marine’s new microcontroller-based senders can be distinguished from our older analog style by an "A" in the part number ex: AFLS, and no trim/adjust potentiometers on the top of the sender. Senders with aluminum tubing are for oil, diesel, or gasoline of up to 10% ethanol; and senders with PVC tubing are for potable water. We do not offer units for non-potable water, which leaves conductive deposits on the sense wire.

  • Senses water in fuel, lets you know by moving the gauge needle all the way to the right
  • No moving parts to wear out or break
  • Reading are not affected by side to side motion or forward movement
  • Installs in the standard SAE 5 bolt pattern mounting plate that is used with a float arm style sender
  • 2 terminal sender works on both 12 or 24 volts
  • 240/33 ohms in stock
  • Bendable senders are available (special order)

Water Level Senders

Livorsi Marine senders work by measuring capacitance. This means that no moving parts are required. Electronics in the head convert the measured capacitance to the programmed output of ohms or volts. In fuel senders, capacitance is measured between the inner-sensing tube and the grounded outer tube, and it requires the fluid to be non-conductive. In water senders, capacitance is measured between the inner insulated sense wire and the water, which is grounded by the outer wire.
