China's level instrument product growth status and market trends

The development status and market trend of China's level instrument products! High-end contemporary new instruments are imported in addition to nights, especially the level gauges used in night-type enterprises are imported instruments, even pressure-type or differential-pressure ultrasonic level gauges are used. Import or joint venture pressure or Drucker differential pressure transmitter. Therefore, the level meter that defies the land and produces the high-end ancestors is still the key to the market of the domestic level meter. The above detailed analysis of the market trend of various level instruments.

The level switch is divided into the low value of the night, and there are points for the liquid level switch and the level switch. At present, the leading product of the liquid level switch is still the float type liquid level switch, followed by the tuning fork type and the capacitive type liquid level switch. This trend will not change very much in the future for a long time in the future. However, with the progress of the management level of the enterprise, not only the meter itself is required to have a low price, but also the request for simple resettlement, high reliability and small amount of shelter. Therefore, the market share of RF admittance (capacitive) and ultrasonic level switches will continue to increase. Due to the simple placement of the RF admittance level switch, no movable parts, high reliability, small amount of repair, and superior to the float switch in pressure and corrosion resistance. The ultrasonic level switch is a non-snoring type measurement, and its superiority is obvious. As its own production price continues to drop, it will also occupy a considerable share of the market.

The solid level switch is currently dominated by the rotary type, followed by the tuning fork type and the capacitive type. However, since the rotary-type level switch is constantly changing, the reliability is low. Therefore, the same source, the market share of RF admittance and ultrasonic level switch will be more than the night, especially the RF admittance level switch is the best type of measuring solid materials at this stage.

The detection of the liquid level of various tower tanks in the production process is still based on pressure and Druck differential pressure transmitters. In addition to its own price/performance ratio, there are other advantages that are planned and manipulated. Secondly, the magnetic float type, buoy type, and capacitive ultrasonic level gauge also have considerable manipulation. With the development of technology, the amount of magnetostrictive, ultrasonic and RF admittance ultrasonic level gauges will increase sharply, and the proportion of pressure (differential pressure) ultrasonic level gauges will decrease. According to the different media and field conditions, various ultrasonic level gauges will have their advantages and will form a diversified place.

Due to the volume of the tank in the tank area, the ultrasonic level gauge is required to be highly accurate. In the past, the float steel strip ultrasonic level gauge was used in addition to the servo type and the static pressure type. However, whether it is a float steel belt type or a servo type static pressure type liquid level gauge, it is not the best way to measure the tank level in the tank area. The floating steel belt ultrasonic level gauge has complicated installation and low reliability. The static pressure ultrasonic level gauge is affected by the medium density and temperature. In order to eliminate these effects, a set of Drucker pressure transmitters has perfect static pressure. The measurement system is also very expensive; the servo-type ultrasonic level gauge has a high precision, but due to its organic machine head structure, it is not possible to prevent the wear of the title, and the cost is also high. Since the 1990s, the radar ultrasonic level gauge has entered the market. Due to its high precision, high reliability and easy handling, it has increased its use in the tank area and has become the preferred instrument for tank level in the past decade. . In recent years, the magnetostrictive ultrasonic level gauge has sprung up. Because of its high precision, high constant, high reliability and long life, it is more suitable for measuring the tank level in the tank area. The amount of manipulation is bound to increase, and it will gradually become radar. The ultrasonic level gauge is equally divided into autumn colors. The fiber optic ultrasonic level gauge can achieve on-site non-electrical detection and good safety. This is its outstanding advantage. The disadvantage is that there are still many machine transmission components, the obstruction rate will increase, and the placement will be more complicated. The ultrasonic level gauge has a slightly lower accuracy, but its placement is moderately priced, so it will also have a place in the tank area.
