1 UFLS-100 User Manual V1.0 Ultrasonic Fuel Level Sensor UFLS-100 User Manual V1.0 Preface Congratulations on choosing the Mictrack Ultrasonic Fuel Level Sensor UFLS-100. This manual shows how use or config the fuel sensor. Make sure to read this manual carefully before using this product, so as to avoid delays or confusion with it s operation. Please note that specifications and instructions are subject to change without notice to facilitate product improvement. Updates and changes will be integrated into the latest release. The manufacturer assumes no responsibility for any errors or omissions in outdated documents.

2 1. Overview Ultrasonic fuel level sensor UFLS-100 is a vehicle fuel monitoring device which is designed for the fuel management needs of company fleet. This sensor can be used to prevent the driver to steal fuel, optimize the operating costs, optimize the driver s driving behavior and auxiliary statistical decision, etc. The sensor is equipped with a high precision ultrasonic probe, which can detect the fuel quantity in the fuel tank. Fuel quantity data will be sent to the server via our 4G GPS tracker (MT600 Plus need to buy separately ),then generate the data report. 2. Features Easy Installation and use, not dangerous High Sensitivity High Accuracy Better Long Term Stability No pollution and lower consumption. Work perfectly in harsh environments. 3.

5 6. Installation 6.1 Installation preparation The customers need to prepare: 12V power supply, isolating tape, and duster cloth and paper tissue (used to wipe off grease dirt). Before installing the sensor, please make the oil tank full or half of full (Installation is the optimal at this state). 6.2 Actual Oil capacity and installation environment confirmation Oil level prediction: Judge the approximate oil level height of the fuel tank by checking oil meter of the vehicle, knocking the oil tank or opening the tank cover with the help of long and thin wire and make record (for example, the prediction is about 300mm). Before installing it, please make sure the vehicle stops at horizontal ground and the oil tank is placed on frame horizontally (with the help of gradienter). 6.3 Seek installation area The installation area of probe should avoid the oil filler, oil outlet, oil return pipe, oil float and baffle, etc. Select the flat part at oil tank bottom or close to the central area as possible (see the following pictures). For circular oil tank, in addition to avoiding the barrier, the tangent plane closest to the ground should be selected. 6.4 Confirm installation location of Ultrasonic couplant Connect sensor box with user interface wire, extension wire with probe properly and power on. The liquid level will displayed Clean the area where the oil tank is installed. Apply ultrasonic couplant on probe surface and then press the probe at the installation position. The LED display will show the currently liquid level (shown as follow). 4

6 Press the key 1 for 6 seconds and it will enter input state of oil tank height. F060 in following picture means that height of the oil tank is 60cm. Short press key 2 to increase and short press key 3 to decrease. Last press key 1 for 6 second to confirm the parameters. After finish the height of the oil tank. Press the key 1 for 6 seconds and it will enter input state of liquid level of the tank. Following picture E030 means that current liquid level height is 30cm. Short press key 2 to increase and short press key 3 to decrease. After the current liquid level of the tank is put properly, press key 1 for 6 seconds and it will enter the automatic adjustment state of tank signal strength. At the moment, you may check whether the displayed height is consistent with actual oil level (for example, the predicted level is about 300mm and displayed 285.2mm). If the display show or the height is quite different from the actual condition, the probe may be moved slightly or grind the oil tank wall more. In addition, the buzzer in the equipment sounds continuously (if the buzzer sounds on and off or does not sound, it needs to seek the installation point or grind the oil tank wall more until the buzzer does not sound). At the moment, press the key 1" for 6 seconds to complete search and test of installation point. 5

7 6.5 Fix the probe If the location where the probe is pasted at the oil tank bottom still has paint, it is necessary to grind the paint away with sandpaper at the pasting position. Wipe away the oil stain and water to keep the surface dry and clean. Use glue to paste: Use a screwdriver to squeeze component A and component B glue of a graduation and drop them on the probe center. Stir even quickly. The higher the temperature is, the faster the curing speed is. If the temperature is lower than 8, it is necessary to preheat the probe surface before glue is dropped. Paste the probe at the installation location along the direction of vehicle frame. After confirming that the displayed height is correct compared with the actual liquid level and stable (if it is not correct, take off the probe immediately. Wipe dry the glue on oil tank bottom and probe. Select another position beside to paste until the stable pasting position with correct height is found). Press the probe continuously for more than 5 minutes to make the glue cure initially. Use long ribbon to bind the probe and fix it well with proper tightness. After the probe is fixed, please make sure if the height of LED display is consistent with the oil level of the residual oil. Above is the standard installation mode and we suggest install it like that. But If you think this way is very troubles, you can check the indicator to confirm the installation position. If the LED displayed liquid level is consistent with actual liquid level, the indicator will become GREEN (see following picture), this indicates that the installation position is OK,then fix the probe. This method is simple,but the data stability may be influenced if the environment is poor.generally it is not suggested to use. 6

8 6.6 Wiring Arrange the extension wire into the cab. Wiring should follow the crossbeam of the vehicle at the time of wiring. It should not affect the original self unloading hopper, head repair, etc and other original functions. The extension wire should be away from the vehicle s motor to avoid producing electromagnetic interference produced by the motor. The side of the probe and extension wire should be convolved properly to prevent falling off. The extension wire should be at least 20cm distance to the heating parts of the vehicle. Cable tie is used to fix the extension line every 50cm. Arrange the wire at the installation position of the vehicle reasonably. 6.7 Connect the vehicles and confirm platform data Disconnect the power supply and fix the sensor box close to 4G GPS Tracker MT600 Plus and fix it properly; The red wire connect to positive (+12V) and and black wire to negative(-12v) There are three output interface for choose: Analog output: the green wire connect with GPS analog port. The black wire is connected with GPS ground; RS232: The yellow wire (TX) is connect with GPS RX and the blue wire (RX) is connect with GPS TX. The black wire (GND) is connected with GPS ground. RS485: The brown wire (B) is connect with B of GPS; the purple wire (A) is connect with A of GPS and the white wire is connected with GPS ground. Power ON and check if the platform can get the data from the sensor. Any questions please do not hesitate to contact us: Shenzhen Mictrack Electronics Co.,Ltd.
