State of liquid level instruments: zero tolerance for interference with environmental monitoring behavior / since May, many domestic water conservancy and hydropower, environmental governance, artificial intelligence / 5G use and many other pavements have been launched. More than 100000 domestic technology-based enterprises have deepened their investment in human and material resources to realize "made in China 2025", although no concessions have been made in national environmental governance and work benefiting future generations, To realize the rejuvenation of the country through industry,
Monitoring data quality is the "lifeline" of ecological environment monitoring. At a regular press conference held by the Ministry of ecological environment on the morning of June 2, Bai said that with the increasing public attention to the quality of ecological environment, from "going out to see the weather" to "going out to see the air", caring about the monitoring data of ecological environment has become a part of the daily life of ordinary people. The background concentration of ozone produced by the government is increasing. The average annual increase is about 1 microgram, which is consistent with the change trend of background stations in China. This is mainly related to global warming, man-made pollution emissions, and regional large-scale transmission and other factors. The spatial distribution of ozone pollution in China is consistent with PM2.5. The main reason is that volatile organic compounds and nitrogen oxides are not only the precursors of photochemical reaction to o? But also the main precursors of secondary components in PM2.5. In 2019, Beijing, Tianjin, Hebei and surrounding areas, Fenwei plain are not only the heavily polluted areas of PM2.5, but also the areas with high o? Concentration.
Huaheng transmitter manufacturers have developed two core technologies, sensor and intelligent circuit board. Not only do they master all the core component technologies of all products, but also the accuracy of industrial automatic transmitter manufacturers is constantly improving, from level 0.2 to level 0.1. Through the extension of the core technology, other products for measuring flow and temperature can be deformed.
磁致伸缩变送器是将磁子系统耦合过来的液位信号，以间隔1.5μs 发送的脉冲，精确地测量磁致伸缩液位变送器中磁浮子的位置。这个脉冲产生的磁场沿波导管向下传导。当磁浮子的磁场和脉冲电流磁场相遇时，产生“返回”脉冲(又叫“波导扭曲脉冲”)。敏感元件探测到这个“返回”脉冲。根据电流脉冲与“返回”脉冲之间的时间，通过单片机计算出浮子的位置，确定被测液位或界位。防爆变送器安装时仔细核对型号规格及防爆标志ExdIIBT4～T6,ExiaIICT1～T6，在安防确认以后，和现场的工作人员核 磁致伸缩变送器
Magnetostrictive transmitter is a liquid level signal coupled with magnetic subsystem, which can accurately measure the position of the magnetic float in the magnetostrictive liquid level transmitter with a pulse sent at an interval of 1.5 μ s. The magnetic field generated by this pulse travels down the waveguide. When the magnetic field of the magnetic float meets the magnetic field of the pulse current, a "return" pulse (also known as "waveguide twisted pulse") is generated. The sensor detects this "return" pulse. According to the time between the current pulse and the "return" pulse, the position of the float is calculated by the single chip microcomputer, and the measured liquid level or boundary position is determined. During the installation of explosion-proof transmitter, carefully check the model, specification and explosion-proof signs ExdIIBT4 ～ T6, exiaiict1 ～ T6. After the security confirmation, work with the field staff on the nuclear magnetic telescoping transmitter
In order to ensure the authenticity and reliability of the monitoring data of ecological environment, the Ministry of ecological environment mainly focuses on the two aspects of "fidelity" and "cracking down on counterfeits".
This year, the Ministry of ecological environment will continue to strengthen supervision and inspection. We will adhere to the principle of "zero tolerance" for behaviors that interfere with the monitoring of ecological environment, and will not tolerate them when they are found, investigated, and reported. In addition to administrative punishment according to law, if a crime is constituted, it shall be firmly transferred to the judicial organ for criminal responsibility investigation, and the warning and deterrent function shall be strengthened
At present, Xi'an liquid level transmitter manufacturers have three major technical strength, one is the fully isolated intelligent circuit processing unit technology, the other is the manufacturing technology of metal capacitance sensor, and the third is the multi parameter technology of the whole series of throttling devices.
With its own sensor and intelligent circuit board core technology, Huaheng transmitter manufacturers can extend and transform the core technology at low cost according to customer requirements to achieve personalized product customization. The main products are smart (SMART) series pressure transmitter, multi parameter transmitter, flowmeter, temperature sensor and level (liquid level transmitter manufacturer, which provides high performance price ratio industrial automatic transmitter manufacturer products for China's power, petroleum, chemical, metallurgical, cement, mining and other industries
