Electromagnetic flowmeters quantify your emissions indicators

Introduction: In order to better implement the sewage disposal work, the relevant departments in China require the sewage discharge companies to install measuring instruments— electromagnetic flowmeters— at the sewage outlets. This is a standard instrument for measuring the amount of sewage discharged. The water meter also called electromagnetic flow meter, there are two types, i.e. split electromagnetic flowmeter sewage effluent and an integral electromagnetic flowmeter

The death of the Chinese white dolphin

At 5:00 pm on September 28th, fishermen found a stranded white dolphins in the sea area of ​​the typhoon shelter in Yantian Port. Their heartbeat breathing was weak. After inspection, two front fins, tail fins, chest, back, etc. were surfaced with large stones. Injury, in a state of shock. In the 45 days of rescue in the Xiaomeisha Marine World, only the first-class protected animals called "sea pandas" could not survive.

This kind of tragedy has not occurred rarely in China. Some people have expressed emotion: The Chinese economy ranks second in the world, and China's sewage discharge is far superior to the world level. Many similar situations have also occurred in other regions.

Recently, reporters in Yantai, Zhejiang Province, together with the main leaders of the area and the person in charge of the site, conducted an on-site inspection of the entrance of the Yujian River Coastal Road. Wastewater collection and odor are serious there, directly affecting the ecological environment, the landscape of fish and bird rivers, and the lives of the people. It is understood that the pollution of the Yu Bird River is mainly caused by excessive discharge of sewage by the surrounding chemical companies.

According to China's newly introduced industrial wastewater discharge standards:

To achieve the above-mentioned emission standards, for each chemical company may not be able to achieve, and some companies with large emissions requirements to achieve emission reduction standards, which means that their economic interests will be damaged. Everyone in China under the market economy is seeking to enlarge their own interests. No one wants to lose. This kind of reduction of profits and losses is not feasible for some companies.

In order to better carry out the work of discharging pollutants, the relevant departments in China require sewage discharge companies to install measuring instruments, electromagnetic flowmeters , at the sewage outlets. This is a standard instrument for measuring the amount of sewage discharged. The flowmeter, also called sewage electromagnetic flowmeter , has two types, namely a split-type sewage electromagnetic flowmeter and an integrated sewage electromagnetic flowmeter . Their working principle is based on Faraday's law of electromagnetic induction (When a conductive liquid flows through an electromagnetic flowmeter, an induced electromotive force is generated in the conductor, and the induced electromotive force is proportional to the flow rate of the conductive liquid, the magnetic induction intensity, and the width of the conductor. A pair of electrodes is detected and the flow rate can be obtained by calculation.) The electromagnetic flowmeter provides a strong base for the inspection personnel to determine whether the sewage exceeds the standard by quantifying the index of sewage discharge.

At present, many companies install electromagnetic flowmeters at their main sewage outlets. These sewage outlets are for inspection by relevant departments. In fact, the reduction of profits and losses will make these companies try their best to solve such problems as excavation of secrets. The discharge channels are a good way to evade inspections. Although these practices are profit-and-privacy, they are extremely damaging to the society as a whole. It is hoped that relevant departments will intensify the inspection of such illegal enterprises, and also provide a green and healthy environment for humanity.
