⑴ The working principle of the magnetic level gauge is based on Archimedes’ law.
Using the principle that the weight of the float is equal to the weight of the volume of the liquid discharged by the float, the float-equipped with magnetic steel changes with the change of the liquid level.
The position of the magnetic line of force in the float (that is, the actual liquid level position) drives the turning column and the turning plate through magnetic action. When the liquid level rises, the liquid phase turns red.
When the liquid level drops, the gas phase turns white or black. So as to clearly indicate the change of the liquid level in the container.

⑵ A ruler is installed on the display panel so that the liquid level can be read directly. A valve is installed at the lower end of the body for sampling and draining.

The most significant feature of the Magnetic propane tank level indicator is that the liquid medium is completely isolated from the indicator. So it is very safe and durable under any circumstances. Moreover, various types of liquid level gauges are equipped with liquid level alarm and control switches, which can realize the upper and lower limit offside alarm control or interlocking of the liquid level or boundary level.

Equipped with a dry reed chipset liquid level transmitter, it can convert liquid level and boundary signals into two-wire 4-20mADC standard signals. It is transmitted to the computer, regulator, and liquid level indicator to realize remote indication, detection, recording, and control.

Magnetic level gauges are widely used for liquid level measurement and control in various production processes such as petroleum, chemical, metallurgy, pharmaceutical, food, and electric power.

When the ultrasonic liquid level sensor is working, the high-frequency pulse sound wave is emitted by the transducer (probe). It is reflected on the surface of the measured object (water surface). The reflected echo is received by the same transducer (probe) and converted into an electrical signal. The time between sending and receiving the pulse (the movement time of the sound wave) is proportional to the distance from the transducer to the surface of the object.

The relationship between the distance s of sound wave transmission and the speed of sound c and the transmission time t can be expressed by the formula: s=cⅹt/2
The acoustic wave is a kind of media that transmits information. It is closely related to mechanical vibration. The mechanical vibration produced by the impact and movement of objects spreads outward in the form of waves. According to the frequency of the wave generated by the vibration, it is divided into audible sound waves, infrasound waves, and ultrasonic waves. The sound waves higher than 20khz are called ultrasonic waves.

A magnetic Level Gauge is also called a magnetic level indicator. Magnetic Level Gauge is developed based on the principle of buoyancy and magnetic effect. The magnetic float in the measuring cylinder drives the two-color turning column on the external display of the measuring cylinder to flip with the increase (decrease) of the liquid level to be measured. As the position of the float changes, the indicator moves up and down the same amount. Supports top-mounted and side-mounted. It can be used for liquid level detection in high temperature, low temperature, high pressure, strong corrosion, highly toxic and dangerous environments.

Radar Level Measurement System for High Temperature Blast Furnace

Posted on by

Radar Level Measurement System for High-Temperature Blast Furnace. This article is a case introduction for a customized radar level system.

What is a blast furnace?

The blast furnace uses a steel plate as the furnace shell, and the shell is lined with refractory bricks. The blast furnace body is divided into five parts from top to bottom: throat, body, waist, belly and hearth. Due to the advantages of good technical and economic indicators of blast furnace ironmaking, simple process, large production volume, high labor production efficiency and low energy consumption, the iron produced by this method accounts for the vast majority of the world’s total iron output.

During blast furnace production, iron ore, coke, and slag-forming flux (limestone) are charged from the top of the furnace, and preheated air is blown from the tuyere located at the lower part of the furnace along the furnace circumference.

At high temperature, the carbon in the coke (some blast furnaces also inject auxiliary fuels such as pulverized coal, heavy oil, natural gas, etc.) and the oxygen in the air are combusted to generate carbon monoxide and hydrogen. Oxygen, thereby reducing to obtain iron.

The smelted molten iron is released from the iron mouth. Unreduced impurities in iron ore and fluxes such as limestone combine to form slag, which is discharged from the slag port.

The generated gas is discharged from the top of the furnace, and after dust removal, it is used as fuel for hot blast stoves, heating furnaces, coke ovens, boilers, etc.

The main product of blast furnace smelting is pig iron, as well as by-product blast furnace slag and blast furnace gas.

Difficulties in Level Measurement of Blast Furnace Silo

The level detection and control of blast furnace silo is very important to ensure the continuous production of blast furnace. However, due to the particularity of its working conditions, the material level measurement has the following difficulties:

  1. The temperature is too high.
    The temperature of the blast furnace silo is high. Its working temperature range is generally between 200 and 300 ℃.
  2. The dust is large.
    The dried raw materials in the blast furnace silo. Such as carbon, lime, ores, etc., will emit a large amount of dust suspended in the air during the feeding and production process.
  3. Strong impact and wear.
    The height of the blast furnace silo is much higher than that of ordinary containers. The solid material such as block material inside it will have a large downward gravitational impact on the measuring instrument during the feeding process. And each time it causes different degrees of wear and tear to the measuring instrument.
  4. The dielectric constant varies greatly.
    Since the material ratio will change and the mixing is not uniform, it may also be affected by a small amount of steam. Therefore, the dielectric constant of the medium changes greatly. At the same time, more dust in the blast furnace will also interfere with the dielectric constant.

What kind of level meter can be used for blast furnace level measurement, can radar level meter be used?

To solve the problem of blast furnace level measurement, it is possible to use a radar level gauge to measure it. The radar level gauge is a continuous level measuring instrument with a measurement accuracy of up to ±1mm. The temperature can meet the measurement conditions of 1200 degrees, and fully meet the blast furnace material level measurement conditions.

In the blast furnace level measurement process, the most important thing is the selection of the level meter. Only when the on-site measurement conditions are met, can the work efficiency be effectively improved. The selection of radar level gauge can be based on three parameters of measuring medium, temperature and pressure. The second is its installation method and output signal. In this way, the difficult problem of blast furnace level measurement can be easily solved.

Necessity and feasibility of using radar level meter for blast furnace molten iron

The replacement of each product has its necessity and feasibility. It is also necessary and feasible to use radar level gauges to replace manual visual inspection in ironworks.

Before the radar level meter entered the ironmaking plant, many factories used manual visual inspection to measure the liquid level in the blast furnace. This method has many advantages and many limitations.

First of all, the molten iron temperature in the blast furnace is very high, sometimes as high as 1490 ℃, and even exceeds this temperature. Manual visual inspection requires close observation, which is very dangerous for employees who are visually inspecting.

Other seasons are fine. In winter, the visibility is low, the fog is heavy, the degree of danger is self-evident, and the accuracy of the measurement is also very poor.

Secondly, factors such as man-made or weather can easily cause the molten iron cans to be canned or overflowed, resulting in production accidents.

From the above two limitations of manual visual inspection, it is very necessary for ironworks to use meters. At least the safety of employees is guaranteed, and production accidents caused by molten iron overflow can be avoided.

Purge Device

The purging device uses the dynamic pressure compensation method of hydrodynamics to truly reflect the pressure value of each measuring point online. The purging pressure is greater than the measured pressure, which completely solves the blockage and burning of the pressure measurement pipeline under the condition of dusty and high temperature. The use of pressure regulators can stabilize the gas source provided by the power plant to ensure that the flow rate output by the flow controller is stable and runs reliably for a long time.

In the following conditions, a purging device needs to be added to the blast furnace liquid level measurement system:

First, when the measured powder concentration is relatively large, it is necessary to purge;
Second, the concentration of vapor in the measurement medium is relatively large, and condensation is easy to form on the surface of the sensor, which must be purged.
Third, when the temperature is too high, purging and cooling can also be increased.

Since 1956, the 3-A mark has become a registered mark used to prove that the materials, hygienic design, and production and assembly procedures of the equipment affixed to the label meet the requirements of the 3A standard. In order to improve the credibility of the 3-A mark, in 2003, under the leadership of the 3-A SSI, the third party verification (TPV) was implemented.

With the continuous development and progress of the certification, the 3-A symbol far exceeds a symbol. Based on decades of cooperation and recognition of key stakeholders such as dairy products, food health experts, equipment manufacturers, etc., the 3-A brand has been widely recognized in the food processing equipment market. The value of 3A is manifested in many aspects of stakeholders:

1) The value of 3A to food processors
As leading manufacturers, processors and USDA and FDA regulatory health experts have participated in the development of the 3A standard. Users of dairy processing equipment can ensure that their equipment complies with all applicable hygiene regulations and can achieve effective cleaning. And it can be expected that the inspection by the regulatory agency can be successfully completed.

2) The value of 3A to equipment manufacturers
Because of the high recognition of 3A in the sanitary equipment range. It has now become a passport to enter the US food, dairy, and pharmaceutical and sanitary equipment markets. It is also a symbol of global quality products. It is well-known in various markets around the world. Because the 3A symbol has been recognized by almost all health experts and regulatory officials. Products affixed with the 3A logo can be widely accepted worldwide.

At the same time, because each standard details the hygienic aspects of materials, design and manufacturing. Therefore, the equipment meets the requirements of processors and health experts. Standards also reduce mold, tooling costs, and the expected delivery time due to the lack of uniform standards. At the same time, 3A certification has also formed a huge marketing advantage.

FAQ

Where should a flow meter be placed?

Different types of flow meters have different requirements for the choice of installation location. Where to install the specific flowmeter, you need to decide according to the product you purchase.
Such as electromagnetic flowmeter.
1. Choice of installation site:
　　·Choose a place where there is no negative pressure in the measuring tube;
　　·Avoid installing in strong electric equipment accessories such as motors, transformers, etc., to avoid electrical interference;
　　·Avoid places with strong corrosive gas around the installation location;
　　·When measuring mixed-phase fluids, avoid places that cause phase separation;
　　·The ambient temperature should generally be within the range of -25℃～60℃, avoid direct sunlight as much as possible;
　　·Installed in a vibration-free or small vibration environment, if the vibration is too large, fixed supports should be added to the pipes before and after the sensor;
　　·The relative humidity of the environment should be within the range of 10%～90%;
　　·Avoid installing in a place that can be directly drenched or submerged by rain;
2. Requirements for the length of straight pipe section: (D is the inner diameter of the flowmeter)
The electromagnetic flowmeter has relatively low requirements for the front and rear straight pipe sections. Generally for 90° elbows, T-shaped tees, reducers, fully open valves and other flow resistance parts. There should be a 5D straight pipe section away from the center line of the electrode axis of the electromagnetic flowmeter (not the end face of the sensor).
For valves with different opening degrees (such as valves with adjustable opening degrees), the length of the upstream straight pipe section needs to be 10D. One
Generally, the straight pipe downstream of the sensor only needs 3D to meet the requirements. When measuring mixed liquids of different media, the distance between the mixing point and the flowmeter must be at least 30D.
3. Installation position and flow direction:
The electromagnetic flowmeter can be installed on the pipeline horizontally, vertically and obliquely

What does a flow meter control?

The flow meter itself does not have a control function. The flowmeter can output signals according to the requirements of your control system. Such as 4-20mA, pulse signal, etc. And HART or, RS485, etc.
If you need a flow meter with a switch output function, it should be a flow switch.

What is the most accurate flow meter?

Generally speaking, the accuracy of mass flow meters is the highest. What is measured is mass quantity, which is a flow meter often used as a trade settlement.
The flowmeter can generally reach 1.0 level, and 0.5 level is considered high accuracy. The accuracy of liquid flow meters is generally 0.2%-0.5%.
Of course, the accuracy of the flowmeter still depends on the site conditions. If the measurement of temperature and pressure is not very difficult, the accuracy of the flowmeter must be relatively high. In addition, to ensure the accuracy of the flowmeter, correct installation and use are also very important.

How do you clean a flow meter?

The cleaning method of the flowmeter should be determined according to the type of the flowmeter and the measured medium. It can be rinsed with water, or a cleaning solution can be used according to specific conditions. It is best to remove and clean.
