Status and Development Trends of Level Meter Market - Focus on Microfluidic Control Technology

Level meters are an indispensable instrument for industrial production. China has a vast territory and a wide range of industries. Therefore, there is a large demand for level meters. During the "10th Five-Year Plan" period, about 75,000 to 80,000 units are needed each year. This is a big market and the competition is fierce. There are numerous domestic level instrument manufacturers, but most of them are products with low technical content and low prices. There are many sales units but the value is not high. High-end modern modern instruments are mostly imported, especially for large-scale enterprises. The level meters are basically imported instruments, and even pressure or differential pressure ultrasonic level gauges use pressure or differential pressure transmitters from imported or joint ventures. Therefore, the development and production of high-end advanced level instruments are still the key to occupying the domestic level instrument market. The following is a detailed analysis of the market trends for various level meters.
Level switch market trends
Level switch is a large amount of low value products, there are liquid level switch and level switch points. At present, the leading product of liquid level switch is float level switch, followed by tuning fork type and capacitive liquid level switch. This trend will not change much in a long time in the future. However, with the improvement of the management level of enterprises, not only the price of the instrument itself is low, but also the installation is simple, the reliability is high, and the maintenance amount is small. Therefore, the market share of RF admittance (capacitive) and ultrasonic level switches will continue to increase. Because of the simple installation of radio frequency admittance level switch, no moving parts, high reliability, small maintenance, and better than the float switch in pressure and corrosion resistance. Ultrasonic level switches are non-contact measurements, and their superiority is obvious. As their own manufacturing prices continue to decrease, they will also occupy a considerable share of the market.
The solid level switch is currently mostly blocked in rotation, followed by tuning fork and capacitance. However, due to the continuous rotation of the rotary level switch, the reliability is low. For the same reason, the market share of RF admittance and ultrasonic level switch will increase significantly. In particular, the RF admittance level switch is the best type for measuring solid materials at the current stage. Market Trend of Ultrasonic Level Gauge

Ultrasonic level gauges have very different applications and therefore have many different types.
In the production process, the detection of liquid level in various types of tower stills is still based on pressure and differential pressure transmitters. In addition to its own cost-effectiveness and certain advantages, there are also customary problems in design and application. Followed by magnetic float type, buoyancy type, capacitive ultrasonic level meter also has a considerable amount of application. With the development of technology, the use of magnetostrictive, ultrasonic, and radiofrequency admittance ultrasonic level gauges will increase rapidly, and the proportion of pressure (differential pressure) ultrasonic level gauges will decrease. According to different media and site conditions, various
The advantages of ultrasonic level gauges will form a diversified situation.
Because of its large volume, tank storage tanks require highly accurate ultrasonic level gauges. In the past, most of them used float-belt type ultrasonic level gauges. Servo and static pressure models also had a certain amount of application. However, whether it is a float strip, servo or static pressure ultrasonic level gauge, it is not the best way to measure the tank level in the tank area. The float-belt ultrasonic liquid level gauge has complicated installation and low reliability; the hydrostatic ultrasonic liquid level gauge is greatly influenced by the medium density and temperature. To eliminate these effects, a complete static pressure measurement system is also very expensive. Servo ultrasonic level gauge has high precision, but due to its mechanical transmission mechanism, it will inevitably bring about the problem of wear, and the price is also high. Since the 1990s, radar ultrasonic liquid level gauges have entered the market. Due to their high precision, high reliability, and ease of use, the amount of use in the tank area has rapidly increased. . In recent years, magnetostrictive ultrasonic liquid level gauges have risen rapidly. Because of their high precision, high stability, high reliability, and long lifespan, they are more suitable for tank level measurement in tanks, and their application will also rapidly increase. Ultrasonic liquid level meter evenly divided. The optical fiber ultrasonic liquid level gauge can be used for on-the-spot powerless detection and has good safety. This is its outstanding advantage. The disadvantage is that there are still many mechanical transmission components, the failure rate will increase, and the installation will be more complicated. Ultrasonic level gauges are slightly less accurate, but they are simple to install and affordable, and therefore have a place in the tank area.
