Difficulties Existing in Liquid Level Measurement in Industrial Storage Tank Industry

Most liquid fuels used in industry, such as liquefied petroleum gas, gasoline, diesel, lubricating oil and other refined oils, as well as liquid chemical gases. For example: liquid ammonia, liquid chlorine, are stored in a high-pressure airtight container. In the production process, in order to ensure the safety of production, it is necessary to regularly measure the liquid level of the remaining liquid in the closed container.

Because these liquids are flammable and explosive. Using the traditional liquid level measurement method will cause damage to the tightness of the container. Safety accidents such as liquid leakage are prone to occur. In particular, after the storage tank has been built and put into service. It is hoped that another principle that is different from the existing level gauge will be added, and a level gauge with a different principle will be used. It’s hard for businesses to choose.

80GHZ Radar Level Transmitter Measurement Principle

The general principle of the FM continuous wave radar level gauge is that the radar emits electromagnetic waves on the top of the tank. And the electromagnetic waves are received by the radar after being reflected by the medium.

The frequency difference δf between the received signal and the transmitted signal is proportional to the distance R from the surface of the medium:

R=C (speed)*δf (frequency difference)/2/K (frequency modulation slope).

Because the speed of light C and the frequency modulation slope K are known.

The frequency difference δf can be estimated to obtain the distance R from the radar installation position to the material surface.

And then through the known total height of the tank. Subtract the spatial distance from the radar to the material surface (referred to as Empty height) to get the height of the material level.

Cement Silo Level Measurement

Cement silo seems to be a simple supporting equipment for concrete mixing plant. In fact, it also contains many auxiliary devices. It is not just a simple silo. It also includes auxiliary devices such as dust collector, arch breaking device, pressure safety valve, Level meter, etc.

The material level meter is mainly used for automatic detection and control of the limit material level of various materials such as cement and fly ash. It is indispensable. What does it do?

The material level meter is a sensor used to sense the height change of the material in the container. It can continuously detect the height, volume and other values ​​of the material in real time and convey relevant information to the computer or display instrument.

In the concrete mixing plant, the cement silo is a closed material storage device. The user cannot intuitively understand the amount of powder in it. At this time, a material level meter is needed.

Simply put, the material level meter in the cement silo can accurately record the position of the material in the cement silo, which is convenient for management.

After understanding the function of the level meter, what are the characteristics of the level meter?

1. Anti-interference, ready to use:

Because there are no complicated electronic components and their amplifying circuit parts inside. Therefore, the level gauge is not subject to any electromagnetic wave interference. After installation, it can be used for a long time without any debugging and maintenance.

2. Super anti-shake performance design:

There are no false signals even when the material is flowing.

3. Shock resistance and anti-loosening structure design. Effectively avoid loosening and slipping of parts. High-quality stainless steel material is used to make it have excellent corrosion resistance and wear resistance.
4. The material level meter adopts contact measurement. The result is real, accurate and reliable. It can be installed horizontally, inclined and vertically. It is easy to install and use.
5. Material level display function:

Adopt long-life high-brightness indicator light. The material level display is intuitive and convenient.

6. Excellent measurement reproducibility and adaptability to environmental conditions:

That is, it is not affected by changes in material particle size, shape, specific gravity, medium, wall scale, adhesion, temperature, humidity, dust concentration, etc.

7. Double protection function:

The overload protection function prevents the blades from being damaged by excessive external force. The automatic protection function enables the material level device to be powered off when the rotation of the material blades is blocked in the silo, which protects the motor and effectively prolongs its service life.

The Difference Between Material Level Indicator and Level Switch

First of all, the concept of Material Level Indicator and Level Switch is different.

Broadly speaking, Material Level Indicator is divided into two types: switch type and continuous type. It means that Material Level Indicator includes level switch.

In a narrow sense, the Material Level Indicator can detect the material level change in the container in real time, and can achieve continuous measurement. The material level switch only has the function of switching value, which can only monitor and control the point position, and cannot achieve continuous measurement.

Of course, in general, the instruments for continuous measurement use the naming method of Material Level Indicator. Most of the instruments for switching values use the naming method for level switches.

Secondly, the products covered by Level Switch and Material Level Indicator are different.

Divide from a narrow concept.

The material level switch mainly includes vibrating rod material level switch, resistance rotary material level switch, tuning fork material level switch, radio frequency admittance material level switch, etc.

Material Level Indicator mainly includes Ultrasonic Material Level Indicator, Radar Material Level Indicator, Ray Level Indicator, etc.

Why is Boiler Drum Level Measurement important?

In the boiler evaporation equipment, the boiler drum is an important part. The natural circulation loop of the boiler is composed of it, the upper header, the lower header, the lead-out pipe, the descending pipe and the water cooling wall. How the boiler drum level is controlled will affect the following aspects.

When the liquid level of the boiler drum is too high. The space where the steam is located is reduced. This results in increased water carryover in the steam. Causes the steam quality to deteriorate. This is one of them. Second, the water level is too high, and the superheater pipe is easy to accumulate salt scale. The tube is overheated and damaged.

The above two situations will occur when the water level is too high. What happens when the steam drum is full of water?

When the steam drum is full of water, there will be a lot of water in the steam. Severe hydraulic shock to steam lines.

The boiler drum water level is too high or too full. So is it too low?
The answer is of course no.

When the water level in the drum is too low, the water circulation will be disrupted. The water wall will exceed the usual temperature and overheat. If the water level is low to a certain extent, there is a serious water shortage. The device is likely to be severely damaged. even lead to accidents.

From the above content, it can be seen that the high and low water level of the boiler drum will have a certain impact on the safe operation of the boiler. In severe cases, it may even affect the safe operation of the unit. Therefore, it is very important to control the liquid level of the boiler drum. The use of liquid level gauges for liquid level measurement is also an inevitable result.

Liquid level data, seemingly unimportant, is actually very important. So no matter what industry, you must understand your own working conditions when choosing a liquid level sensor. Select the liquid level sensor according to the working conditions, so as to choose the appropriate one.

Guided wave radar level transmitter measures drum level

A new type of Guided wave radar level transmitter is used to measure the liquid level of the steam drum of a certain device. The level gauge is certified as a limiting device for high temperature water (HW) and low temperature water (LW) containers. Complies with EN12952-11 and EN12953-9 (TUV certified) standards.

Guided wave radar level transmitter with GPC function technology. Improve the accuracy and reliability of the Guided wave radar level transmitter in high temperature and high pressure environment.

GPC technology

Under high temperature and high pressure conditions, the propagation speed of electromagnetic wave signals in the vapor above the medium (polarized medium) will decrease. At this time, the liquid level value measured by the radar will decrease.

Use guided wave radar with gas phase automatic compensation. Guided wave radar produces a reference reflection within the distance from the flange (measurement reference point), which varies along the rod probe.

Under normal temperature and pressure. The electromagnetic wave has two reflected echoes at the compensation reference end and the liquid level reflecting surface. The measurement is accurate at this time. At this time, the reference distance (the distance from the measurement reference point to the reference rod) is calibrated.

At high pressure, due to the polarization effect of the gas. At this time, the measured distance (the distance from the measurement reference point to the liquid level) has a large deviation from the actual value of the liquid level. if not compensated. Then there will be a large error in the measurement value.

The measured value is compensated by converting the reference reflection.

The calculation formula is: compensation distance = reference distance × (measured distance/measured distance). An accurate actual liquid level value can be obtained.

Application

The steam drum of the boiler plant is the main part of the steam production system.

Use the high temperature heat in the flue gas section of the reformer and the high temperature waste heat of the reformer gas at the furnace outlet. Produce 10.5MPa high pressure steam.

Part of it participates in the reaction as the steam distribution in the process. The other part is sent to the high-pressure steam pipe network to realize the comprehensive utilization of thermal energy and improve the operation efficiency of the device.

Because the traditional measurement can not meet the measurement requirements well. It is necessary to choose other products to replace.

Due to the importance of the steam drum to the boiler plant. To measure the liquid level of the steam drum, three measuring instruments are designed and used: Guided wave radar level transmitter and differential pressure liquid level level transmitter.

Measured by example. At high temperature, the measurement error of ordinary guided wave radar (without GPC) is as high as 18%. With GPC, the measurement error is only 2%.

The measurement data of the GPC guided wave radar level gauge at high temperature is relatively stable and true.

Therefore, it is a perfect combination of guided wave radar technology with GPC and advanced signal processing technology. This makes the guided wave radar level gauge with GPC an ideal solution for level measurement in steam and turbulent boiling conditions.

Wastewater Level Sensors Types

In sewage treatment, the level of waste water, sludge, chemical solutions, etc. needs to be measured. In the sewage treatment system using automatic control. The Level Sensor is used to measure liquid level. Many also involve the start and stop of interlocking pumps and the opening and closing of control valves in automatic control.

Compared with other types of measuring instruments, there are many types of level gauges suitable for sewage treatment projects. There are two types of contact and non-contact measurement.

All of the above must be considered. Pay attention to the physical and chemical properties of different measured liquids according to different types of Level Sensors.

The following will analyze the selection of the sewage treatment Level Sensor according to the combined process.

Ultrasonic Septic Tank Sensor

Septic tank ultrasonic level meter is used as an instrument to intelligently detect the height of the septic tank. Played a vital role in the maintenance of public toilets.

In the previous toilet maintenance, the manure trucks were cleaned regularly and fixedly. Doing so will inevitably cause some waste of resources.

Install septic tank ultrasonic level gauges in public toilets. The liquid level of the manure tank can be monitored in real time. It will automatically alarm when it reaches a certain height. The transmission system is connected to the control center. The front calls the police and the rear supports.

This can greatly save manpower and material resources. It is of great significance for energy saving, environmental protection and resource saving.

Septic tank ultrasonic level meter needs to be equipped with automatic alarm device or SMS alarm device. Ultrasonic module with 485 communication is used for liquid level monitoring. And through multiple communication modules with 485, the liquid level is monitored uniformly by the unified terminal system. This can not only display in real time. It is also possible to remind the user management personnel through a text message reminder or terminal alarm device when the septic tank is almost full.

Septic Tank Alarm Float Switch

The float level switch is specially used for liquid level detection of various medium and small normal pressure and pressure liquid storage tanks, remote transmission of on-site indicator signals, and liquid level alarm. It can be applied to various sanitary, toxic, corrosive media and explosive gas dangerous places. There are also many types of installation. Suitable for various forms of containers.

External Tank Level Indicator

The external tank level indicator is a new type of non-intrusive ultrasonic level measurement system. This is a real non-invasive, non-contact measurement method.

Just install the measuring probe on the outer wall of the bottom of the tank or container. The reflection and transmission characteristics of ultrasonic waves are used to realize the measurement of the liquid level inside the storage tank.

The calculated liquid level value is displayed locally, and a remote signal is output. The meter can output the measurement result to the control system through 4-20 mA analog signal, HART, RS-485 and other interfaces. At the same time, data can also be sent to the Internet via wireless transmission via WIFI, GPRS and NBIOT.

When the ultrasonic wave emitted by the probe propagates to the inner wall of the bottom of the container. The first reflected echo is generated due to the change of the propagation medium. After that, the ultrasonic wave continues to propagate in the measured liquid medium. When propagating to the gas-liquid interface, the propagation medium changes again. Produce a second reflection echo.

Assume that the time difference between the first reflected echo and the second reflected echo is T. According to the propagation speed c of the ultrasonic wave in the measured liquid. The liquid level value L =c*T/2 can be obtained in the container.

The advantage of this liquid level measurement method is that there is no need to open holes or install flanges for the container to be tested. The internal liquid level information can be obtained directly from the outside of the container. The non-intrusive liquid level measurement is truly realized.

Marine Holding Tank Level Indicator
