The laser level transmitter is a non-contact level gauge. The product is powerful, sturdy and durable. It has excellent accuracy and high stability. It achieves accurate, non-contact and uninterrupted real-time monitoring of material height. Industrial site and process, river water level monitoring, material height monitoring and other occasions have very broad applications.

Laser level transmitter working principle

The laser level transmitter adopts the phase method laser ranging technology. Using the frequency of the radio band, the laser beam is amplitude modulated and the phase delay produced by the modulated light going back and forth to the measuring line is measured. Then according to the wavelength of the modulated light, the phase delay represented by this is converted distance. That is, the indirect method is used to measure the time required for the light to pass through the measuring line.

The distance D from the surface of the material is proportional to the time travel T of the pulse:

D=C×T/2

Where C is the speed of light

Since the distance E of the empty tank is known, the level L is:

L=E-D

According to the range and full scale information set by the user, the processor calculates the percentage of the current material level, and then outputs 4-20mA or 0-5V analog signals, RS485 Modbus digital signals, and warning alarm relay switch signals in proportion.

The importance of Silo/Bin level monitoring

In the production process of the mixing station, the material in the powder silo is replenished in time by means of pneumatic conveying. Most of the dust collectors on the top of the powder silo of the mixing station lack normal maintenance. During the replenishment of the tank body, the pressure of the powder silo is too high, causing “roof fall”. Cement overflows from the dust collector or safety valve. Or “lift the top”, the separation of the top cover of the powder silo from the body of the powder silo occurs.

The intelligent safety system of the powder silo passes through the intelligent detection equipment installed on the silo. achieve:

• Predict the amount of storage in the warehouse and control the amount of feed;
• Three-level protection to prevent the occurrence of “top falling” and “lifting top” accidents;
• Prevent the wrong storage of cement, fly ash, and mineral powder, and prevent construction quality accidents;
• Cloud platform monitoring platform, real-time monitoring of the status parameters of the powder silo;

Advantages of Radar Silo Level Sensors

High frequency radar Silo Level Sensor is currently the mainstream product for measuring solid level in the world. When measuring solid material level, compared with low frequency radar, high frequency radar has the following advantages:

1) High-frequency radar level gauges (mainly 26GHz and 24GHz) have the advantages of high energy, small beam angle and high precision. However, low-frequency radars have low energy and scattered energy, so all launch angles are large and the directivity is poor. When the diameter of the horn antenna of the low-frequency pulse radar is Φ246, the beam angle is only 15°).

2) The wavelength of 26GHz radar is 11mm, and the wavelength of 6GHz radar is 50mm. When the radar measures the bulk material level, the radar wave reflection mainly comes from the diffuse reflection of the material surface. The intensity of diffuse reflection is proportional to the size of the material and inversely proportional to the wavelength. That is to say, for the same material, the shorter the wavelength is, the easier it is to be reflected, so the echo signal is better during radar measurement. The diameter of most bulk materials is far less than 50mm, which is why 26GHz radar is currently the best choice for bulk material level measurement.

3) Due to the harsh environment on site, dirt, water vapor, etc. will accumulate on the radar antenna over time. The 26GHz radar antenna is small, adding a radome can greatly improve the impact of dirt and water vapor. The 6GHz radar antenna is large, and it is very difficult to add a radome. The overall instrument is large and difficult to clean.

4) When the low-frequency radar (6GHz) measures solids, the measurement range will not exceed 30m. It cannot meet all level measurements of cement lines above 2500T/d scale. The general measurement range of high-frequency radar can reach 70 meters, or even 100 meters. It can fully meet all silos of cement production lines of all scales at present.

5) Because the high-frequency radar level gauge has good directivity and small launch angle. Strong anti-interference ability and so on. It is determined that it is very suitable for the measurement of silos with large aspect ratios. Especially such as calcium carbide furnace material level, converter silo and other material level measurement. Neither of these situations can be measured with low frequency radar.

6) Low frequency radar compared to high frequency radar. Due to its low frequency, the energy is scattered and the energy is not concentrated enough. Therefore, the ability to fight against dust is far inferior to high-frequency radar.

It is generally composed of transmitter, sensor and pressure probe. The sensor is a special metal rod or cable with a built-in capillary hose, and the probe is constructed as a stainless steel cylinder core with a diaphragm at the bottom.

The probe intrudes into the liquid and tests the difference between the static pressure of the liquid and the actual atmospheric pressure, which varies with the liquid level. The electronic components receive the differential pressure signal to reflect the change in liquid level. According to the different materials of sensors are divided into two types of rod and cable type.

Liquid level meter measured by reflection

Water Tank Level Monitoring and Control Systems

Water Tank Level Monitoring and Control Systems are a sophisticated set of technical devices used to track and manage water levels in water tanks in real time. Such systems typically include key components such as level sensors, controllers, displays, and actuators (such as pumps or valves).

• Water Tank Level sensors are the core of the system, responsible for measuring and transmitting water level data. These sensors can be of various types such as float type, pressure type, ultrasonic type, capacitive type, etc., selected according to different application scenarios. They convert water level changes into electrical signals and send them to the controller in real time.
• The controller is the brain of the system. It receives signals from the sensors and makes judgments based on the preset water level range. For example, when the water level is below the minimum limit, the controller will start the water pump to fill the water. When the water level reaches the maximum limit, the water pump will be stopped or the drainage valve will be opened to avoid overflow.
• The display provides the operator with an intuitive interface showing current water levels, as well as system status and alarm information. This information helps operators understand whether the system is functioning properly or if manual intervention is required.
• Finally, actuators, such as pumps and valves, are the actual devices that respond to controller commands and are responsible for physically regulating the flow of water. The system can automatically or manually adjust these mechanisms as needed to maintain water level stability.

Therefore, with Water Tank Level Monitoring and Control Systems, automatic management and control of water tank level can be achieved.

When the water level of the water tank drops to the set lower limit water level value, the liquid level controller sends a command to instruct the pump valve to open the water supply.

When the water level reaches the set upper limit water level value, the controller will issue an instruction to instruct the pump valve to close and stop the water supply.

In the same way, if necessary, the liquid level controller can also instruct the water pump or electric valve to perform the opposite operation.

Know more about Liquid Level Switch

Liquid level switch, also known as water level switch, liquid level sensor. As the name implies, it is a switch used to control the liquid level.

In terms of form, it is mainly divided into contact type and non-contact type.

Commonly used non-contact switches include capacitive liquid level switches, and contact float-type liquid level switches are the most widely used. Electrode liquid level switches, electronic liquid level switches, and capacitive liquid level switches can also be realized by contacting methods.

Continuous Float Level Sensor

The floating ball continuous level gauge uses the floating ball to move up and down with the liquid to trigger or release the reed switch in the tube, and output 4-20mA or other different standard models through circuit processing.

With multi-interface measurement, easy to install, and corrosion-resistant, it can meet most measurement needs. Suitable for various tanks and tank level measurement, optional on-site display.

Point Level Float Switch

The float level switch uses a magnetic float to rise or fall with the liquid level. The sensor detects the reed switch chip at the set position in the tube, and sends out a contact opening (closing) conversion signal.

One or more dry reed pipes are installed in the closed non-magnetic pipe. Then the pipe passes through one or more hollow floats with ring magnets inside. The rise or fall of the liquid will drive the floating ball to move up and down together. Then the reed tube in the non-magnetic tube will pull on or off, and then output a switch signal.

According to needs, one or more liquid level switch points can be set.

Whether it is Continuous Float Level Sensor or Point Level Float Switch, they all need to be in contact with the medium.

However, in some cases, we need to measure and control the liquid level without contacting the medium. Then we can consider the following liquid level sensors.
