Electromagnetic flowmeter is composed of sensor and transmitter. Its operating principle is based on the Faraday's law of electromagnetic induction. The subject could be electric liquid or liquid and solid medium, and the conductance not lower than 5μs/cm, which equal to the soften water. The conductance of the general tap water and the natural water is about 100-500 μs/cm. Therefore, the acid, soda and salt liquid, the paper slurry , the mineral slurry, etc, can all be measured effectively. Note that the subject can't contain too many Fe-magnetic substances or bubbles.
Electromagnetic flowmeter is the main flow meter for the electric liquid measurment. It is widely applied in the municaipal management, water building and the many other fields such as metallurgy, chemical industry, paper making, environmental protection, petroleum, light&textile industries, foods, municipal management, irrigation infratructure and so on.

Characteristics 

1. As there are no blocking flow and active parts in the measuring pipe, no additional energy will be caused lost and no blocks will be formed. It's very effective in energy-saving, especially applied well in the two-phased flow measuring such as the wastewater, the slop, the mineral sulrry, water-coal slurry, the paper slurry, and et al.
2. As only the lining and the electrode contact the measuring medium, if their materials are properly chosen, good erosion-resistance and abrasion-resistance will be achieved. So the flowmeter can be used to measure various chemical liquids such as thick acid, alkali and so on
3. Mount quite easy, there needs 5D for the front straight pipe and 2D for the back straight pipe
4. High measuring accuracy, could reach ±0.2%
5. Consists of dual frequency excitation wave, not violated from the working frequency and all other electromagnetic fields, stable in performance
6. Only consumes a very little power(<20VA)
8.Operable flow range is wide, could reach 1500:1
