Since calcium carbide silo is an open container, the upper limit of the material needs to be limited to ensure the safety and smooth production, and the rotary level switch is more often used for calcium carbide level measurement. However, in the actual application, due to the working conditions and the performance of the instrument itself, the rotary level switch has advantages in the measurement of calcium carbide material level, but there are also some problematic points.

Magnetic flap level meter is common side mounted magnetic flap level meter and top mounted magnetic flap level meter two. So, what are the characteristics of the side-mounted magnetic level gauge, and what do you need to pay attention to in the process of its use?

In industrial production, pulse radar level meter and guide wave radar level meter are two kinds of radar level meters widely used at present. Nevertheless, there are still many instrument users who can't distinguish the difference between these two level meters, and don't know which level meter is used in what occasion.

In the whole conveying process, the material level control is the key to ensure the conveying efficiency, but because the physical characteristics of different materials are not the same, how to choose the right level switch for the characteristics of different powders and granules in pneumatic pull cord conveyor?

The main types of liquid level meter are: magnetic flap level meter, ultrasonic level meter, radar level meter, laser level meter and so on. With the advantages of economical and practical, easy installation, contactless measurement, wide adaptability and not affected by sludge blockage, scouring and liquid corrosion, ultrasonic level meter is very suitable for water level measurement in sluice gate project.

Radar level meter is a more commonly used level measurement instrument, which has the characteristics and advantages of accurate measurement, easy maintenance and wide application, and is quite popular. However, in the actual application process, due to the more complex working conditions or improper use and other reasons, there are often failures. In this paper, the common problems and solutions in the application of radar level meter are introduced as follows.

In level measurement, liquid level measurement, material level measurement and boundary level measurement also have different characteristics due to the different materials measured. These different level measurements have different performance in the actual working conditions and have different requirements for the level measurement instruments​.

We all know that in the conveying system, the operating condition of the belt conveyor is directly related to the safety of the equipment and personnel in the production process. Therefore, how to make the belt conveyor protection device stable and reliable in the production operation to give full play to the role of safety protection, has a very important practical significance.

What is rotameter？The main measuring element of the glass rotameter with transmitter is a vertically mounted conical glass tube and a float that can move up and down.

In the orifice plate flowmeter use stage, its process pipeline needs many times of blowing, it is necessary to frequently disassemble and install the orifice plate flow meter.

Vacuum-jacketed magnetic flap level meter is a kind of level measuring instrument which is very suitable for working in low temperature.

The magnetic flap level meter can realize the purpose of local display and remote (with remote transmitter) liquid level measurement. For different measurement environments and working conditions, the adaptability of the magnetic flap level meter can be greatly enhanced by the addition of suitable components. Among the many parts of the magnetic flap level gauge, the flange valve is a very important structural part of the magnetic flap level meter.

Magnetic level sensor is a continuous level measuring instrument which uses magnetic coupling principle to display or detect the change of liquid level height in real time. It is widely used in pharmaceutical, electric power, paper making, metallurgy, water treatment, petrochemical, food processing and other fields for liquid level monitoring. However, in some applications with strong magnetic field interference and corrosive environment, the magnetic flap level gauge sometimes can not be used normally, affecting the smooth and normal production of safety, so how to avoid such events has become a top priority in safe production.

Radar level meter is a measurement instrument used for level detection and control, radar level meter is also known as radar water level meter, radar level transmitter, radar level gauge, etc., in fact, they are all a measurement instrument. For the radar level meter selection, only know the measurement medium, you can come up with a solution, you can see how much experience this needs to have and accumulated.

As we all know, the formation of an explosion needs to meet three conditions, namely for oxygen, explosive gases, detonation source. Explosion-proof measures must be taken in the electrical engineering, installation and construction, operation and maintenance and safety and technical management of explosion-hazardous places to achieve overall explosion-proof. The use of explosion-proof instrumentation without safety hazards can play a real protective role.
