1. Stabaxol I
2. What does AFM mean?
An electromagnetic flowmeter is composed of two parts: a sensor that directly contacts the pipeline medium and an upper signal converter. It works based on Faradays law of electromagnetic induction and is used to measure the flow rate of conductive liquids with a conductivity greater than 5 μ s/cm. It is an instrument for measuring the flow rate of conductive media. In addition to measuring the flow rate of general conductive liquids, it can also be used to measure highly corrosive liquids such as strong acids and alkalis, as well as liquids with uniformly suspended liquid-solid phases, such as mud, slurry, pulp, etc. Electromagnetic flowmeter and Shunda instrument
3. Abbreviations for various sensors in automobiles
1. Oxygen sensor: When the oxygen sensor fails, the ECU cannot obtain this information and does not know whether the amount of gasoline injected is correct. Improper air-fuel ratio can lead to a decrease in engine power and increase emission pollution;
2、 Wheel speed sensor: It mainly collects the rotational speed of the car to determine whether there are signs of slipping. Therefore, there is a specialized sensor for collecting the wheel speed of the car to complete this task. It is usually installed on the hub of each wheel, and once the sensor is damaged, the ABS will be ineffective;
3、 Water temperature sensor: When the water temperature sensor malfunctions, it often displays the temperature signal of the hot car when starting the cold car. The ECU cannot receive the correct signal and can only supply a thinner mixture to the engine. Therefore, it is difficult to start the engine when it is cold, and it may also be

4、 Electronic accelerator pedal position sensor: When the sensor fails, the ECU cannot measure the accelerator position signal and cannot obtain the correct position of the accelerator pedal, resulting in weak engine acceleration and even engine failure to accelerate;
5、 Intake pressure sensor: As the name suggests, an intake pressure sensor senses a series of resistance and pressure changes with different engine speed loads, converts them into voltage signals, and provides ECU with correction of fuel injection quantity and ignition timing angle. Usually installed on the throttle side, if there is a malfunction, it can cause problems such as ignition difficulty, unstable idle, and weak acceleration.
