Analysis on the future potential of my country's market for measuring instruments such as level meters and

With the continuous intensification of China's scientific and technological process, all walks of life have achieved unprecedented improvement and progress, and the country's attention to the instrument industry has gradually increased. Among them, the liquid level measuring instrument is an industrial automation instrument that measures the liquid level and loading height of liquid and powder materials, and has a wide range of applications in industry. Therefore, the liquid level instrument has a huge development prospect. So what is a liquid level measuring instrument and what are its characteristics? What is the market development potential? Let's find out.

Liquid level measuring instrument and its characteristics

The liquid level measuring instrument is an instrument that measures the liquid level, solid particles and powder level, as well as the position of the liquid-liquid and liquid-solid interface in the industrial production process. It is related to the quality of the product, the safety of the production process, etc., and the application is also more important. For example: the water level of a large-capacity boiler in a power plant is a very important process parameter. Too high or too low a water level will cause serious safety accidents, so it is required to accurately measure and control the boiler water level.

In addition, the water level of the water tower, the oil level of the oil tank, the coal block stacking height of the coal bunker, and the liquid level of the reaction tower solution in chemical production all need to be measured by a liquid level measuring instrument. So, what measuring instruments does it have? It is reported that liquid level measuring instruments can be divided into direct reading liquid level instruments, electric measuring liquid level instruments, ultrasonic liquid level instruments, etc. according to the physical principles used. But do you know them?

Magnetic flap level gauges , float level gauges, and glass tube level gauges are all direct reading liquid level gauges. Direct reading liquid level gauges are generally used for liquid level measurement in on-site liquid storage equipment. They have a simple and durable structure, are easy to install and maintain, and have clear and intuitive readings. In addition, since the liquid level gauge is in direct contact with the measured medium, the process parameters such as operating temperature, pressure, and viscosity that the liquid level gauge can withstand should be considered when using it.

The electric measuring liquid level instrument converts the liquid level change into the change of electrical parameters, and then converts it into an electrical signal output; it works on the principle of causing the electrode resistance to change when the liquid level changes. The resistance changes gradually due to the change of the liquid level, which can be used to continuously measure the liquid level; the resistance changes suddenly only when the liquid level changes to the contact electrode, which can be used for fixed-point alarm to control the liquid level.

The advantage of ultrasonic level meter is that the detection element can be kept away from the measured liquid, so it is suitable for the measurement of highly corrosive, high-pressure, toxic and high-viscosity liquid levels. In addition, it is not afraid of smoke and light, and is not subject to electromagnetic interference. It can measure the liquid level of various liquids and the level of powdery solids. It can also be used to measure the interface between two liquids, the level difference, and the level difference. After learning so much about level measuring instruments, do you think it has a good market potential?

Market potential from the current development status

According to statistics, the overall scale of China's physical/liquid level instrument market reached 1.57 billion yuan in 2018, an increase of 12.1% compared with 1.4 billion yuan in 2017, and the market growth is relatively stable. It is expected that the growth rate of China's physical/liquid level instrument market will remain between 11-12% in the next three years. Due to the vast territory and complete industrial categories in China, the demand for liquid level instruments is huge, the industry market demand is hot, capital is favorable to the field of liquid level instruments, and the industry development is long-term positive. The growth of downstream industry transaction scale provides new development momentum for the liquid level instrument industry.

In addition, the level meter is an important instrument that is indispensable for industrial production. At present, the instruments used for level measurement are mainly: vibrating rod level switch, magnetic flap level meter, radio frequency admittance level switch, rotary resistance level switch, float level meter, tuning fork level meter, ultrasonic level meter and radar level meter. Since the level measuring instrument can reduce the loss of materials, save energy efficiently, improve production efficiency and reduce safety accidents, the advanced level measuring instrument occupies a pivotal position in industrial production.

However, due to the relatively weak industrial foundation of our country, the instrument industry is no exception, especially in the field of level measurement. For a long time, the measurement method was primitive and the measurement accuracy was low, which was far from the advanced products abroad. In addition, in the field of level measurement with relatively high technical content, domestic instrument enterprises are still relatively weak, which makes some domestic users rely more on suppliers from foreign manufacturers.

Therefore, Chinese enterprises should strengthen the accuracy requirements for level measurement, continuously improve and innovate the performance of level instrument products, improve the quality of products, develop more excellent level instrument products, and strengthen the functional effectiveness of instrument products. In short, the development space of the liquid level measuring instrument industry will become larger and larger in the future, and the market demand will also increase. It is not too late for related companies to know now. As long as related companies seize the opportunity, there is no need to worry about the road to development. So, what should they do specifically? The editor summarizes the following points for everyone, hoping to be helpful to you.

Development direction of liquid level measuring instruments

Although the liquid level measuring instrument market has huge development potential, related companies must also "go right" to develop. At this stage, how can liquid level measuring instrument companies take the right path?

First of all, we must develop towards intelligence. Due to the advancement of microelectronics technology, instrumentation products are further integrated with microprocessors and PC technology, and the digitalization and intelligence level of transmitters are constantly improving. In the future, the development of liquid level measuring instruments will have intelligent products, certain controllability and data processing capabilities. For example, radar level gauges. Looking at the liquid level instrument market, radar level gauges are products with relatively broad applications, good reputation and significant effects. In addition, there are guided wave radar level gauges , radio frequency admittance level gauges and other product types that adapt to different working conditions and industrial production requirements.

Furthermore, enterprises should take market demand as the criterion for product development. Change the past principle of blindly pursuing "high, precise and advanced" to the principle of user demand. The measurement method tends to be "non-contact measurement". Non-contact liquid level measuring instruments are not mainstream yet, but they are developing rapidly and attractive, such as ultrasonic, laser and microwave liquid level measuring instruments. They also develop new liquid level detection instruments. Only by bringing forth the old and getting rid of the old can the liquid level measuring instrument be more advanced.
