Intelligent liquid level display transmitter

I. Overview of the popularity of smart liquid level display transmitters based on single-chip microcomputers. Intelligent liquid level display transmitters are more and more popular among users. The smart liquid level display transmitters are widely used in petroleum, electric power, and environmental protection. Chemicals, paper, metallurgy, construction and other industries, praised by users. The intelligent liquid level display transmitter consists of two parts. One is the field smart meter. The second is a smart level transmitter.

Second, the advantages of intelligent liquid level display transmitter:

1. Strong anti-interference ability The intelligent liquid level display transmitter has extremely strong anti-jamming capability. In the parallel or vertical lines with strong and weak currents, when the same direction and lines in different directions are laid, normal and stable display is maintained. And control work. It is not affected by the AC sine wave.

2. The signal transmission distance is far from the intelligent liquid level display transmitter, which can transmit signals over long distances. Generally, it can transmit a distance of 10km without being limited by the distance of the line.

3, the measurement accuracy is high The level accuracy of the intelligent liquid level transmitter is up to two thousandths of an inch.

4, easy installation Intelligent liquid level display transmitter installation is very simple, as long as the smart liquid level transmitter into the liquid, the smart liquid level display box installed in a suitable location, with a wire to the smart liquid level transmitter Connected with the intelligent display, and then connected to the power and control, alarm device to complete the installation.

5. It is convenient to debug the debugging of the intelligent liquid level display transmitter. As long as the method is set in the display of the display, it can be set according to the steps. The control signal can be arbitrarily set at a certain position for control or alarm.

6. Intuitive smart liquid level display adopts energy-saving LED luminous strips and digital components, both analog light display and digital display of numerical results.

Third, the application of smart liquid level display transmitter application The following examples of practical applications of smart transmitter, to play its unique characteristics, to solve the various problems in the process control measurement. It should be pointed out that on the market, there are various types of smart transmitters, and the internal functions will have different characteristics. Therefore, the individual examples cited in this article may not necessarily be generic, and the reader is requested to identify them.

1: Practical application example A five-star hotel, the original underground reservoir, the use of a float level switch, a simple alarm and control of the liquid level, due to the control of large errors, poor reliability, control methods have no way to resist The power supply interfered with the water tank and caused severe water shortages in all rooms of the five-star hotel.

After receiving this news, our company immediately organized the engineering and technical personnel of our company to go to the investigation. After inspection, we discovered the above problems and promptly recommended the general manager of the engineering department of the large five-star hotel to take rectification.

The general manager of the five-star hotel held an emergency meeting in time and decided to adopt the company's rectification plan after research.

A. The rectification plan is as follows:

1. Using the original signal transmission line, remove the float level switch.
2. Use a smart liquid level display transmitter to perform real-time detection of the liquid level in the reservoir to control the high and low water levels of the reservoir.
3, set the ultra-high, ultra-low water level sound and light alarm.
4. Remote display of the level signal to the duty room, showing the change of the reservoir.

B. Specific requirements:

1. When the water level in the reservoir reaches a low water level, open the electric valve on the water intake pipe to supplement the water in the reservoir and begin to feed water.
2. When the water level of the reservoir reaches a high water level, close the valve on the inlet pipe and stop the water intake.
3. If there is a fault in the electric valve, the water level in the reservoir will continue to increase if the water can't be turned off and the water level in the reservoir will continue to rise. When the water level exceeds a high level, an ultra-high sound and light alarm will be issued.

4: to facilitate the display of various parameters of the scene IV. Conclusion Although the price of smart transmitter is slightly higher than the floating ball level switch, but its performance and price than the non-conventional float level switch can. The above case illustrates the features and advantages of the smart liquid level transmitter and its unique performance. With confidence, peace of mind and peace of mind. In short, the reasonable choice of smart display liquid level transmitter, there is no problem of oversizing, it can help self-control personnel to increase production efficiency, reduce inspection workload, reduce workload, improve work efficiency, and ultimately improve the level of automated water supply operations.

The reason why it is called "the application of intelligent liquid level display transmitter" is mainly because in the near future, the intelligent liquid level display transmitter is truly well-known and fully reflects its advantages. Replace traditional float level switches to solve practical problems. For this reason, only as an application of experience, dedication to peers and the majority of business owners.
