The Acu-Trac® Smart 485 family ultrasonic liquid level transducers are designed for continuous level monitoring and liquid level control applications. These non-contact continuous level transducers can monitor tanks or storage containers that have a depth of up to 1.9 meters (75.69 inches) for gasoline and 2.5 meters (98.4 inches) for other media. The Acu-Trac® Smart 485 ultrasonic transducers incorporate a RS-485 bus for real time processing of liquid levels in two messaging formats. The Smart 485 liquid level transducers offers three electrical outputs for level control in the following forms:
4-20 mA Current (12V or 24V input)
Ratiometric Voltage 0.5 to 9.0 Volt (12V input)
Non-Ratiometric 0.5 to 9.5 Volt (24 Volt input).
The Smart 485 liquid level transducer is designed with power up self diagnostics and allows the user flexibility through programmable features:
Tank Configuration Profiling
Digital Filtering
Gauge Drive Output (full and empty endpoints)
Communication Mode.
Note: An Acu-Trac® Smart 485 Configuration Kit is required to program the liquid level transducer.
Accuracy: 2 % full scale of tank volume
Reliability: Acu-Trac® Smart 485 liquid level transducers are non-contacting. Resistive float senders have a wiper that slides across a resistive strip that with time can wear out and cause intermittent or complete loss of the signal.
Non-Invasive: Acu-Trac® Smart 485 mounts to the same opening as the resistive float sender, but does not protrude into the tank.
Digital Filtering: User programmable time constant in digital filtering eliminates errors due to fluids sloshing in mobile tanks.
Tank Profiling: User programmable strapping tables for unique tank shapes.
Chemical compatibility: Acu-Trac® Smart 485 works with a wide variety of media including diesel, gasoline, motor oil, hydraulic fluid, black water, and more.
Self Test/Diagnostics: Internal Power Up Test verifies transducer is operating properly.
Continuous Real Time Liquid Level Monitoring: Electrical output and RS-485 messaging data.
RS-485 Messaging: Two types of messages – programming commands and timed data broadcast messages. (See AT-AN14 for more details)
