Ultrasonic Fuel Sensor User Guide 1. Introduction This document is designed to introduce the ultrasonic fuel sensor and offer users instructions on how to install the fuel sensor correctly.
Ultrasonic Fuel Sensor User Guide 2. Product Introduction 2.1. Product Parts List The product is composed of one ultrasonic sensor detector and one signal control box. k n i l l c a i t e n u Q fide n o C Ultrasonic Sensor Detector Signal Control Box Power Wire Signal Extension Wire Control Box Ultrasonic Detector User Connector Figure 1.
Ultrasonic Fuel Sensor User Guide 2.2. Technical Parameters Table 1: Technical Parameters Items Parameters Operating Voltage 5－36V 50mA Operating Temperature -40℃－80℃ Measurement Range 5cm－2m Pressure Range -0.1MPa－32MPa k n i l l c a i t e n u Q fide n o C Level Accuracy 3mm Level Measurement Accuracy Theoretical 0.
Ultrasonic Fuel Sensor User Guide 2.3. Product Feature 2.3.1. High Accuracy The measurement resolution of the fuel level is 0.2 mm and the level accuracy is 3 mm. The sensor automatically performs the temperature compensation in the range from -40℃ to 80℃. This ensures the measurement accuracy even when the environment temperature is extreme high or low. 2.3.2.
Ultrasonic Fuel Sensor User Guide 2.4.3. Fuel Flow Meter This type of fuel sensor is difficult to install as it has to truncate the original fuel pipe. It can measure the fuel consumption, but not the amount of refuelling, which makes it inconvenient for measurement and management. 2.4.4. Reed Switch Fuel Sensor This type of fuel sensor has low accuracy and is very easy to be influenced by the measurement media and temperature fluctuation caused by power voltage.
Ultrasonic Fuel Sensor User Guide 3. Principle Analysis This chapter mainly illustrates the principle of the ultrasonic fuel sensor and the common fuel sending units and partitions. k n i l l c a i t e n u Q fide n o C Figure 2. Principle Diagram 3.1. Principle Liquid level in a container is measured by coupling the transducer to the bottom of the container using couplant. The transducer generates a short ultrasonic sound pulse which is transmitted through the container wall and into the liquid.
Ultrasonic Fuel Sensor User Guide 4. Installation This chapter deals with the installation procedure of the square and round fuel tank. 4.1. Installation of Square Fuel Tank 4.1.1. Preparation Fill up the fuel tank and park the vehicle on a horizontal surface, and prepare all the installation tools and auxiliary materials as shown below.

Locations and Structures of Obstacles in Square Fuel Tank 4.1.3. Locate the Installation Area According to the principle of the ultrasonic fuel sensor, the gauged liquid depth could be wrong if the ultrasonic wave is hindered by the obstacles such as supply or return tube and fuel sending unit.
Ultrasonic Fuel Sensor User Guide k n i l l c a i t e n u Q fide n o C Figure 6. Locate the Installation Area Note: the installation area must avoid the possible area with fuel sediments, that is, the prominent surface of the fuel drain bolt. As shown below, the old detector on the left is a faulted one because of the fuel sediments.
Ultrasonic Fuel Sensor User Guide Figure 7. Fuel Drain Bolt Please make sure that the installation area does not obstruct the installation of the stainless steel hose clamp. k n i l l c a i t e n u Q fide n o C 4.1.4. Test Draw an area at the bottom of the fuel tank corresponding to the area available to installation at the top. Wash this area by removing all the grease, dirt and sands on the surface and dry it with a rag.
Ultrasonic Fuel Sensor User Guide Figure 9. Fuel Level and Signal Value Note: Sometimes, the gauged liquid depth is 000mm and the signal strength is 000 when the vehicle is stationary. In this situation, fill the fuel to more than 80% of the full capacity and start the vehicle engine, if the correct depth can be obtained with the signal strength ranging from 1 to 2 by shaking the vehicle, then we can judge the location is suitable for installation.
Ultrasonic Fuel Sensor User Guide used to fix the detector cable. Please refer to the following figures. Figure 11. Stainless Steel Hose Clamp After the detector and the installation surface become dry, put on the disposable plastic mitten and spread glue in the center of the detector. Don't put too much glue.

Ultrasonic Fuel Sensor User Guide 4.2. Installation of Round Fuel Tank 4.2.1. Observe Tank Surface Observe the locations of obstacles such as the fuel sending unit, supply tube, and return tube. k n i l l c a i t e n u Q fide n o C Figure 14. Surface of Round Fuel Tank Judge the structures and locations of obstacles inside the fuel tank based on the observation of those obstacles on the surface. Figure 15. Locations and Structures of Obstacles in Round Fuel Tank 4.2.2.

Installation Area of Round Fuel Tank k n i l l c a i t e n u Q fide n o C Please avoid selecting installation location that will hinder the installation of the stainless steel hose clamp. 4.2.3. Test Refer to 4.1.4. 4.2.4. Finish the Installation Refer to 4.1.5.
Ultrasonic Fuel Sensor User Guide 5. System Connection System connection includes correct wiring and installation of the signal control box. 5.1. Wiring Wire along the vehicle frame for future maintenance. Don't affect the vehicle's functions of dump bucket and vehicle head maintenance. The detector and the extension wire should be wrapped with tape for the purpose of water resistance, and fix them on the stainless steel hose clamp with plastic cable ties. Please refer to Figure 17.
Ultrasonic Fuel Sensor User Guide 5.2. Installation of the Control Box The control box should be fixed on the installation surface of the vehicle with Velcro. Install it on the horizontal surface and fasten it with cable ties. The interface definition of the control box is as follows. k n i l l c a i t e n u Q fide n o C Figure 18. Interface Definition of Control Box Power interface: connect to the vehicle’s battery. GPS tracker interface: connect to GPS tracker device as shown in Figure 19.

Ultrasonic Fuel Sensor User Guide 6. Attention Pay attention to your own safety during installation. Connect cables to the positive and negative of batteries in the correct way. The power interface should not contact other circuits and metal parts of vehicles. Don’t cut or connect circuits arbitrarily in the vehicles. Take some shock-absorbing measures when fixing the signal control box if possible.
