Analysis of Development Status of Level Meter Products

Most modern high-end instrumentation is imported. In particular, level meters used in large-scale enterprises are basically imported instruments. Even pressure or magnetic 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. Article Summary:

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 this stage.

Magnetic tilt level gauge market trends

The use of magnetic flip level gauges is very different, so the variety is also numerous.

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, buoy, capacitive magnetic level gauge also has a considerable amount of application. With the development of technology, the use of magnetostrictive, ultrasonic and RF-admittance magnetic flap level gauges will increase rapidly, and the proportion of pressure (differential pressure) magnetic flap level gauges will decrease. According to the differences in media and on-site conditions, various magnetic flap level gauges will show their advantages and will form a diversified situation.

Tank storage tanks, due to their large volume, require high accuracy of the magnetic flip plate level gauges. In the past most of them used float strip type magnetic flap level gauges. Servo and static pressure also have a certain amount of application. However, whether it is a float-belt, servo-type or static-pressure magnetic flap level gauge, it is not the best way to measure the tank level in the tank area. The float strip type magnetic flap level gauge is complicated to install and has low reliability; the static pressure type magnetic flap level gauge is greatly influenced by the medium density and temperature. To eliminate these effects, a complete set of static pressure measurement system is provided. The price is also high; the servo-type magnetic flap liquid 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 magnetic level gauges have entered the market. Because of their high precision, high reliability, and ease of use, their use in the tank area has rapidly increased, making them the first choice for tank level in the last decade. meter. In recent years, magnetostrictive magnetic flap 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 volume will also increase rapidly. And the radar magnetic leveler is evenly divided. The fiber-optic magnetic level gauge can achieve on-site power-free detection with 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.
