1. SSI Technologies Application Note DT AN2 Digital Fluid Trac DFT 100 Ultrasonic Drum Level Gauge Troubleshootine Press On Off and Hold until Back light turns on Measurement Technology The Digital Fluid Trac DFT 100 drum level gauge uses ultrasonic technology to generate a high frequency sound wave and measures the time for the echo to reflect off the target fluid s surface and return The distance from the Digital Fluid Trac s sensor to the liquid is calculated based on the speed of sound The Digital Fluid Trac DFT 100 is designed to work on ANSI MH2 standard 55 gallon drums height of 32 for 55 gallon volumes For correct operation the Digital Fluid Trac DFT 100 must be mounted properly with no obstructions between the sensor and media being monitored 1 If using the 4 adapter verify the yellow acoustic absorber disc see photo below is properly installed inside the adapter Level sensor mounting that is not perpendicular to the fluid causes a reduction in level sensor performance As shown in the figure below the amount of returned sound energy is dependent on mounting cone angle Full Scale Range Distance Sensor ep h Target Stand Sl ee Angle SSI Technologies Application Note DT AN2 Digital Fluid Trac DFT 100 Ultrasonic Drum Level Gauge Troubleshootine 2 Verify the Digital Fluid Trac DFT 100 If the previous three conditions are me2. t perform mounting is perpendicular to the liquid The drum the following bench test must be stored in an upright position 4 Simulate a Full 55 gallons Reading a Place the Digital Fluid Trac flat on a table top b Press the On Off button c The display should read 55 gallons 2 gallons 5 Simulate a 35 Gallon Reading a Place the Digital Fluid Trac 12 inches above the table top Make sure the bottom of the sensor is perpendicular to the table top 3 Verify there are no obstructions between the b Press the On Off button sensor head and the media being measured c The display should read 35 gallons If something is between the sensor and the media being tested the sound wave will be reflected off the object and not the media a Place the Digital Fluid Trac resulting in incorrect level readings 32 inches above the table top Make sure the bottom of the sensor is perpendicular to the table top b Press the On Off button c The display should read 0 gallons Distance Reading 6 Simulate an Empty 0 Gallon Reading Copyright March 17 2009 SSI Technologies Inc All Rights Reserved Revision 1
