Good price and quality electromagnetic water flow meter has been widely used in water supply, sewage treatment, chemical industry, medicine, papermaking, food and other industries all over the world. Large diameter instruments are mostly used in water supply and drainage projects.Good price and quality electromagnetic water flow meter with small and medium caliber is often used in solid-liquid double equal, difficult to measure fluid or places with high requirements. Small caliber and micro caliber are often used in places with health requirements such as pharmaceutical industry, food industry and bioengineering. With the acceleration of China's industrialization process, the problem of environmental pollution is becoming more and more serious, and the voice of society for sustainable development is becoming higher and higher. The idea of harmonious coexistence between man and nature is accepted by people, and the treatment of all kinds of pollution is more urgent. In the sewage treatment process, it is necessary to measure and control the discharged sewage, additive sludge, etc., so the flow measurement is very important.
Good price and quality electromagnetic water flow meter cannot measure liquids with low conductivity, such as petroleum products and organic solvents. Gases, vapors and liquids containing large bubbles cannot be measured. It is found from the data that some pure or aqueous solutions have low conductivity and are considered not to be used. However, in practical work, there will be examples that can be used due to impurities, which are beneficial to increasing conductivity. For aqueous solution, the conductivity in the data is measured in the laboratory with pure water ratio. The actual aqueous solution may be proportioned with industrial water. The conductivity will be higher than that found, which is also conducive to flow measurement.
The good price and quality electromagnetic water flow meter is not affected by external factors such as temperature, pressure and viscosity. There is no pressure loss caused by shrinkage or projection inside the measuring pipe
In addition, the initial signal detected by the flow element is a voltage that changes linearly with the average flow rate of the fluid. It has no relationship with other properties of the fluid and has great advantages. According to the characteristics of sewage such as large flow change, impurities, low corrosivity and certain conductivity, good price and quality electromagnetic water flow meter is a good choice to measure the flow of sewage. It has compact structure and small volume. The installation, operation and maintenance are convenient. The measurement system adopts intelligent design, with strong overall sealing, and can work normally in a harsh environment. Therefore, in the water and sewage industry, electromagnetic water flow meter, especially large-diameter electromagnetic flowmeter, has great advantages and has been widely used.
Good price and quality electromagnetic water flow meter is generally powerful and easy to operate. The specific characteristics are as follows:
1) There are no flow blocking parts and pressure loss in the measuring pipeline, and the bottom of the straight pipe section is required.
2) The measurement is not affected by the changes of fluid density, viscosity, pressure, temperature and conductivity.
3) The lining is made of hard rubber, polyurethane, PTFE, PFA and other materials.
4) The DC power supply / AC power supply, four wire system / two-wire system, explosion-proof / non explosion-proof, economical and standard types of transmitters can meet the different needs of users.
5) Photosensitive key, which can avoid cover opening operation; Chinese menu display, more convenient for domestic users.
6) Quick setting menu, guide to complete parameter setting, convenient and fast.
7) High measurement reliability, good repeatability and long-term maintenance free. Range ratio up to 1000:1
8) provides various output modes for selection, such as current, frequency, pulse, Hart, PROFIBUS PA, PROFIBUS DP, FF, etc
