The material level indicator refers to an instrument for real-time detection of changes in the height of solid materials in a container. Material level indicator is also known as material level transmitter, material level controller, material level meter, etc.
Level measurement usually refers to the detection of the height of materials (solid or liquid level) in closed or open containers during industrial production. Instruments that accomplish this measurement task are called level gauges. Level measuring instruments are used to monitor liquid or solid material levels. Includes slurries and granular solids.
Material Level Monitoring
Level measuring instruments are industrial automation instruments that measure the liquid level and loading height of liquid and powdery materials. Measure the stacking height or surface position of solid materials such as lumps, granules and powders.
Material Level Monitoring is the measurement of the surface position of solid blocks or powders in a silo to understand the amount of material stored in the silo.
In thermal power plants, it is necessary to detect the position of coal lumps and pulverized coal in the raw coal hopper and pulverized coal bunker.

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?
- 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.
- Super anti-shake performance design:
There are no false signals even when the material is flowing.
- 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.
- 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.
- Material level display function:
Adopt long-life high-brightness indicator light. The material level display is intuitive and convenient.
- 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.
- 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.
Sino-Inst offers over 20 Material Level Indicators for level measurement. For detecting high, intermediate, or low levels of liquids, powders and free flowing granular solids stored in tanks, bins, silos or other containers. About 50% of these are Radar level meters, 40% is other tank level sensor.
