The difference between Ultrasonic Depth Sensor and Ultrasonic Level Sensor

Next, we list the differences between Ultrasonic Depth Sensor and Ultrasonic Level Sensor.

1. The working environment is different

The probe and host of Ultrasonic Level Sensor are placed in the air.

Ultrasonic Depth Sensor works in water. The probe of the Depth Sensor needs to be placed in the water to measure the depth of the water.

2. The measurement distance is different

Ultrasonic Level Sensor ranges in the air between 0-70 meters.

The Ultrasonic Depth Sensor can measure distances of several kilometers in water.

3. The working principle is different

The working principle of the Ultrasonic Level Meter is that the ultrasonic probe part emits ultrasonic waves, which are then reflected by the liquid surface, and then received by the probe part. The distance from the probe to the liquid (object) surface is proportional to the elapsed time of the ultrasonic waves.

The working principle of the Ultrasonic Depth Sensor is designed based on the principle that ultrasonic energy propagates in a straight line at a uniform speed in a homogeneous medium, and is reflected when it encounters different medium surfaces.

Ultrasonic Depth Sensor uses water as the ultrasonic medium. When measuring depth, place the ultrasonic probe at a certain position underwater. The depth from the probe to the bottom of the water can be calculated according to the propagation speed of ultrasonic waves in water and the time interval between sending out and receiving ultrasonic signals.

The purpose of a capacitive level sensor is to accurately and reliably measure the level of materials in various industrial applications.

Capacitive level sensor can measure the level of highly corrosive medium, high temperature medium and sealed container, regardless of the viscosity, density and working pressure of the medium.

Let’s first get to know the working principle of the capacitive level sensor.

capacitive level Measurement Principle

Have you ever wondered how we can measure the level of material in a tank? Well, that’s where the magic of capacitance level measurement comes in!

Think of a capacitor like two metal plates, with a thin layer of insulation in between. When the plates are close together, they can hold more electrical charge. In this measurement technique, the probe acts as one plate and the tank wall as the other. When the tank is empty, there’s plenty of space between the two plates, meaning they can hold very little charge. But as the material fills the tank, the plates move closer together and are able to hold more charge.

So, by measuring the electrical charge between the probe and the tank wall, we can determine just how full the tank is! It’s like a secret code between the sensor and the material in the tank, giving us the scoop on its contents.

Capacitance level measurement is a straightforward, dependable, and non-invasive way to keep track of what’s inside a tank. So the next time you’re curious about how much material is left, just remember the wonder of capacitance level measurement!

1. Operating Frequency

Radar level sensors use radio waves to measure the level of solid materials. And the frequency of these radio waves determines the accuracy and reliability of the measurement.

There are two main types of radar level sensors – pulse radar and frequency modulated continuous wave (FMCW) radar. Pulse radar operates at a higher frequency and provides more accurate measurements, but it is also more expensive. FMCW radar operates at a lower frequency and is less expensive, but it is less accurate.

When choosing a radar level sensor, consider the level of accuracy required for your application, as well as your budget.

Our most common ones are 6GHz-26GHz-80GHz-120GHz. You can refer to more 26GHz-80GHz-120GHz radar level meter parameter comparison. List of Radar Level Sensors

2. Material Properties

The properties of the solid material you are measuring will also impact your choice of radar level sensor.

The dielectric constant of the medium is also easy to be ignored, and attention should be paid to the medium with a small dielectric constant.

The problem of antenna hanging can not be ignored. Due to the strong adhesion of steam belt material and most mud, the radar level gauge will encounter the problem of antenna hanging.

The coating has no effect on the medium with small dielectric constant, but it will affect the medium with large dielectric constant. Influence of Dielectric Constant on Radar Level Meter

Introducing high-pressure wind to blow the antenna near the antenna can prevent material hanging. Some devices can be optionally equipped with a dust cover. At normal temperature, just cover the antenna with plastic film and clean the hanging material regularly.

Also, if the material is very dense or has a high moisture content. It can affect the accuracy of the measurement. If the material is very abrasive, it can wear down the sensor over time.

Consider the properties of the material you are measuring when choosing a radar level sensor.

3. Environment

The environment in which the radar level sensor will be installed can also impact its performance.

For example, if the sensor will be installed in an area with a lot of dust or steam. This can affect the accuracy of the measurement.

If the sensor will be installed in an area with high temperatures. Make sure the sensor is designed to operate in these conditions. Consider the environment in which the sensor will be installed when choosing a radar level sensor.

4. Storage Containers

The type of storage container in which the solid material is stored will also impact your choice of radar level sensor.

For example, if the container is very large, a long-range radar level sensor may be required. If the container is very tall, a high-level radar level sensor may be required.

Consider the size and shape of the storage container when choosing a radar level sensor.

The first is the range problem. When choosing a radar, there is often a misunderstanding, that is, the selected range should only be greater than the height of the tank. In fact, the range marked on the radar may be its maximum range.

The type selection also depends on the characteristics of the container. For example, whether the surface of the storage tank is smooth or corrugated, or even stirred.

The actual level that can be measured by the same radar level gauge is very different in different situations. For example, a certain liquid level gauge has a range of 30m. It is only a smooth surface liquid that can be measured to 30m. Once it is used in a non-stirred and rippled On the buffer tank, the result is different. When using it to measure the material level of more than ten meters of stirring, the low material level is often not measured. This is actually because the selection range is not enough. After increasing the range, the problem is solved.

5. Safety Considerations

Finally, safety considerations must also be taken into account when choosing a radar level sensor.

For example, if the material being measured is flammable, make sure the sensor is designed for use in hazardous areas.

If the material is toxic, make sure the sensor is designed to prevent contamination. Consider the safety requirements for your application when choosing a radar level sensor.

Conclusion

Usually level measurement media include water, slurry and powdery materials. The environment has a good static liquid level as well as a liquid level where a lot of vapor builds up. There are materials with severe dust and more steam environment. There is also pressure. There are also open ones. In short, all kinds of complications abound. So if you want to make good use of the radar level gauge and maximize its value, you must pay attention to these issues.

Choosing the right radar level sensor for solid materials requires consideration of several key factors. Including operating frequency, material properties, environment, storage container, and safety considerations. By taking these factors into account, you can choose a specific me radar level sensor that you needs and provides accurate and reliable measurements.
