The Fluid-Trac™ cost-competitive liquid level sensor family is ideal for tanks or storage containers that have a depth/height of 32 inches (24 inches for gasoline). These liquid level sensors are chemically compatible with gasoline, diesel fuels, ethanol, oils, fresh water, sewage water, UREA (AdBlue) and engine coolants. A minimum order quantity of 10 units is available through our distribution partner. Orders of 100 units or more are available from the factory direct, test samples are available for large opportunities.

Fluid-Trac™ Options


  • The Fluid-Trac™ 2-wire liquid level sensors are non-contact sensors that can be used as a more reliable and accurate replacement for standard 30-240 ohm resistive float sender, reed-switch tube sensors or capacitive tube senders.
  • The Fluid-Trac™ is 2-wire liquid level sensor is commonly used to work with fuel gauges.

Three-Wire Resistive Output

  • The Fluid-Trac™ 3-wire Resistive Output liquid level sensor can be factory programmed to have a resistive output in the range of 8 to 320 ohms. The Fluid-Trac® 3-wire resistive output liquid level sensor allows direct replacement of 33-240 ohm float senders or 10-180 ohm float senders.

Three-Wire Voltage Output

  • The Fluid-Trac™ 3-wire ultrasonic level sensor is a non-contact liquid level sensor that offers a wide variety of input and output options which enables it to interface with many different microprocessor-controlled fuel gauges or digital instrumentation.

Focus Tube Application

  • The Fluid-Trac™ Focus Tube Adaptor (FTA) is designed to be mated to the SSI Technologies, Inc. Fluid-Trac unit with 5 bolt mounting specification. FTA will fit on tanks with SAE J1810 bolt pattern.

Minimum order quantity of 100 units, test samples are available for large opportunities.
