boat fuel gauge installation
The sensor is resistive, with the red wire connected to the signal and the blue wire connected to the negative pole. After the oil tank is placed, the highest oil level shall not be 2.5 meters higher than the diesel generator set base. It is mainly about one positive and one negative wire on the oil meter, of which the positive wire must have electricity, and the resistance on the oil float must also have one incoming and one outgoing wire, and then it can be connected in series with the two wires on the oil meter. The negative wire connected in series must be grounded.
The boat fuel gauge is generally installed in front of the ship's driving position, on the same dial as the water temperature, speed, speed and other indicators. Each gauge is distinguished by a simple icon. The fuel gauge is represented by a rectangular icon.
Today's ships generally have a fuel pump in the fuel tank, which is controlled by the computer to extract fuel and transport it to the engine. The boat's fuel gauge transmitter is located in the car's fuel tank. It is connected to a buoy, which is usually made of foam plastic. The end of the metal rod is mounted to a variable resistor. A resistor is a device that prevents the passage of current. The greater the resistance, the smaller the current through. There is no difference in the operating principle between the oil gauge and the oil level sensor. The boat fuel gauge and the oil level sensor generally have two types of wire and three types of wire. As long as they are matched with each other and the color of the wire is the same. A float is installed on the fuel pump. The float itself is connected to a sliding resistance. The float floats up and down in the gasoline. The change of liquid level causes the change of resistance, so that different electrical signals will be transmitted to the engine computer. Finally, after computer calculation, confirm how much fuel is in the tank.
It seems that the working principle of the oil gauge is quite scientific, but in fact, there are many factors that may cause the inaccurate display of the ship's oil gauge. For example, the float is stuck by the wire in the oil tank, or the wire transmitting the electrical signal from the oil pump fails, or the engine computer has problems, many factors will affect the display of the ship's oil gauge.
