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

The Fluid-Trac® 3-wire liquid level sensor can be factory programmed to have a ratio-metric output to drive 12V fuel electronic gauges (automotive applications).

The Fluid-Trac® 3-wire liquid level sensor can also be factory programmed to provide a non-ratiometric voltage output (0.5 to 4.5 V) for interfacing to control modules, PLC controllers, digital instrumentation, or DAQ systems to indicate tank volume levels.

• More Reliable: Fluid-Trac® is non-contacting. Resistive float sender have a wiper that slides across a resistive strip that with time can wear and cause intermittent or complete loss of the signal.

• Non-Invasive: Fluid-Trac® mounts to the same opening as the resistive float sender, but does not protrude into the tank.

• Easier to Install: Fluid-Trac® has no components to protrude into the tank.

• Digital Filtering: Digital filtering eliminates errors due to liquids sloshing in mobile tanks.

• Tank Profiling: Factory programmable strapping tables for unique tank shapes.

• Chemical compatibility: Fluid-Trac® works with a wide variety of media including gasoline, diesel, motor oil, hydraulic fluid, black water.

• Tank Volumetric Error Detection: Optional factory programmed non-ratiometric voltage output with "in range" values for error detection.

• Minimal Dead Band: No bottom dead band like on other senders. Optional Fluid-Trac® mounting adapter can be used to reduce or potentially eliminate the top dead band.

• American Boat and Yacht Council (ABYC) Certified
