SSI Technologies - Application Note AT-AN1 Acu-Trac® Ultrasonic Fluid Level Sensors Product Overview

Product Description

The Acu-Trac® family of ultrasonic fluid level sensor is non-contact fluid level sensors that are a direct replacement for level senders on tanks with depths up to 3.0 m. The ultrasonic fluid level sensor provides a choice of either analog current loop (4-20 mA) or voltage outputs (ratiometric or non-ratiometric) with the additional capability of processing real time fuel data and messaging on a J1708 data link.

Product Features

More Accurate: 2% of tank volume. More Reliable: Acu-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: Acu-Trac® mounts to the same opening as the resistive float sender, but does not protrude into the tank. Easier to Install: Acu-Trac® has no components to protrude into the tank. Digital Filtering: User programmable time constant in digital filtering eliminates errors due to fluids sloshing in mobile tanks. Real Time Fuel Data: Real time fuel data over the J1708 data link for both on vehicle and off vehicle communication. Remote, Real Time, Automated Fuel Data Reporting: Works with mobile communication systems to reduce operating costs and improve fuel efficiency in the following applications: 1) Fuel Purchase Optimization 2) Low Fuel Warnings to Prevent Running Out of Fuel 3) Fuel Fraud Detection 4) Fuel Tax Odometer Support 5) Fuel Tax Idle Fuel Rebates 6) Fuel Usage Report containing Tank MPG and Idle Fuel Tank Profiling: User programmable strapping tables for unique tank shapes. Chemical compatibility: Acu-Trac® works with a wide variety of media including diesel, motor oil, hydraulic fluid and black water. Self Test/Diagnostics: Power Up Test verifies sensor is operating properly and diagnostic messages are sent over the RS-485 bus. NEMA and CE Mark Class B Ratings
