In recent years, the water level of rivers in many provinces in the south of China has skyrocketed ten The water level of three hydrological stations exceeded the alarm, the water level of Poyang Lake and Dongting Lake exceeded the alarm, and the water level of Taihu Lake ranked the first in a row fifteen When the water level exceeds the warning level, the Ministry of water resources raised the emergency response of flood and drought disaster prevention level III to level II, and the national flood control headquarters also upgraded the emergency response of flood control level III to level II.
Let's talk about it first electromagnetic flowmeter The principle of measurement and its application in the field of water conservancy engineering. YJ-LDE Series electromagnetic flowmeter is a high intelligent flowmeter product based on Faraday's law of electromagnetic induction YJ-LDE The measurement accuracy, reliability and stability of the series electromagnetic flowmeter have been improved, and the service life of the electromagnetic flowmeter has been increased. At present, YJ-LDE Series electromagnetic flowmeter is widely used in petrochemical, machinery manufacturing, metallurgical power generation, paper and textile, food and pharmaceutical, sewage treatment, environmental protection supervision and other fields.
This morning, the Ministry of water resources, the national development and Reform Commission and other departments held a briefing on flood control, drought relief and major water conservancy projects, which revealed some important information, including the arrangements to be made one hundred and fifty It is estimated that the total investment of the major water conservancy projects is about one point two nine Trillion yuan, driving direct and indirect investment of about six point six Trillion yuan.
The characteristics of the electromagnetic flowmeter are that the measurement is not affected by the changes of fluid density, viscosity, temperature, pressure and conductivity, there is no obstructed flow part in the measuring pipe, no pressure loss, and the requirement of straight pipe section is lower; the nominal diameter is lower DN15.5 ～ DN3003 。 There are many choices of sensor lining and electrode materials; the converter adopts novel excitation mode, which has low power consumption, stable zero point and high accuracy. The flow range can reach one thousand five hundred and three ： one The flow meter is a two-way measurement system with three integrators: total forward, total reverse and total difference; it can display, reverse and multiple outputs: current, pulse, digital communication HART agreement.
Recently held two thousand and twenty The third annual central water conservancy investment plan implementation and scheduling meeting calls for speeding up the construction of major water conservancy projects. For projects that are expected to be approved for feasibility study this year, the feasibility study review and approval as well as the handling of key elements should be completed as soon as possible, so as to strive for more development and give full play to the role of major project investment. I hope that the electromagnetic flowmeter industry can take the opportunity of this major water conservancy project to get out of the current industry dilemma.
