How does an oil level sensor work?

Ultrasonic externally attached oil level sensor uses the principle of ultrasonic echo ranging. The sensor is installed outside the bottom of the fuel tank and sends out an ultrasonic signal from the bottom, which is reflected by the oil surface, and then calculates the height of the liquid level according to time and speed.

At the same time, combined with digital signal processing technology, it overcomes the influence of the container wall and realizes high-precision non-contact measurement of the liquid level in the container, which can meet the requirements of industrial applications in terms of application.

Ultrasonic Oil Level Sensor Installation Steps

Step 1. Choose the installation location

① When selecting the installation area at the bottom of the fuel tank, try to avoid the oil outlet pipes at both ends of the fuel tank and the barrier position near the oil inlet, and try to choose the ideal installation area at the middle position.

②Clean up the dirt at the installation location with a rag at the selected location. Please do not polish the paint layer at the bottom of the fuel tank before confirming the installation point, so as to avoid the wrong location and waste installation man-hours.

Step 2. Test and confirm the installation point

①Spread the prepared clean water on the sensing area of the probe, and add as much water as possible to ensure that the air on the contact surface between the sensor and the fuel tank is removed, and then the sensor is fixed to the fuel tank to select the installation position.

②Connect the waterproof head of the display board and the waterproof head of the oil level sensor, insert the USB plug of the display board into the pre-prepared mobile power supply, and observe whether the data on the display board is stable to determine whether the selected point is correct.

Step 3. Fix the ultrasonic oil level sensor

① Polish the selected installation point with sandpaper to remove the paint layer to ensure that the installation surface is flat, and clean it again with a rag to ensure that no dirt enters the sensor before installation.

②Use a glue gun to hit the glue into the sensor’s sensing area, and use a toothpick to mix the glue evenly, and then fit it to the fuel tank installation position. The glue will initially solidify in 4-5 minutes at room temperature, and then prepare the wiring.

Ultrasonic liquid level sensor is a digital liquid level meter controlled by microprocessor.

In the measurement, ultrasonic pulses are emitted by a sensor (transducer). The sound wave is reflected by the liquid surface and received by the same sensor. It is converted into an electrical signal by a piezoelectric crystal. Measure the distance to the surface of the liquid.

Due to the non-contact measurement, the measured medium is almost unlimited, and it can be widely used in the measurement of the height of various liquid materials.

In fact, there are many types of oil level sensors. Different types of oil level sensors work differently.

For example, the External PasteUltrasonic Oil Level Sensor mentioned in this article is based on ultrasonic measurement.

There is also a common capacitive oil level sensor. The sensing part of the capacitive oil level sensor is a coaxial container. When the oil enters the container, it causes a change in the capacitance between the sensor housing and the sensing electrode. This variation is converted through the circuit and performs accurate linear and temperature compensation, and outputs a 4-20mA standard signal for the display instrument.

The working principle of the ultrasonic liquid level sensor is:

Ultrasonic transducer (probe) emits high-frequency pulse sound waves, and the surface of the measured level (material) is reflected back. The reflected echo is received by the transducer and converted into an electrical signal. The propagation time of the sound wave is proportional to the distance from the sound wave to the surface of the object.

The relationship between the sound wave transmission distance S and the sound speed C and the sound transmission time T can be expressed by the formula: S=C×T/2.

The probe part emits ultrasonic waves, which are then reflected by the liquid surface. The probe part is received again. The distance from the probe to the liquid (object) surface is proportional to the elapsed time of the ultrasonic wave:
hb = CT2
Distance [m] = time × speed of sound/2 [m]
The temperature compensation formula of sound velocity:
Ambient sound velocity = 331.5 + 0.6 × temperature
