Electromagnetic Water Flow Meter
Electromagnetic water flow meter can measure the conductivity ≥5μs/cm flow of acid, alkali, salt solution, water, sewage, corrosive liquid and mud, mineral pulp, paper pulp, etc. But electromagnetic flow meter can not measure the flow of gas, steam and pure water. Electromagnetic water flow meter can be used for various water , such as fresh water, drinking water, waste water, salt water, sea water etc.
Electromagnetic water flow meter output signal is linear with the measured flow rate, and the accuracy is high. Electromagnetic flow meter can measure the conductivity ≥5μs/cm flow of acid, alkali, salt solution, water, sewage, corrosive liquid and mud, mineral pulp, paper pulp, etc. But electromagnetic flow meter can not measure the flow of gas, steam and pure water. Electromagnetic water flow meter can be used for various water, such as fresh water, drinking water, waste water, salt water, sea water etc.
What is the main features of Electromagnetic water flow meter?
1. Changes in fluid density, viscosity, temperature, pressure, and conductivity have no effect on measurement;
2. The measuring tube has no obstructive parts, no pressure loss, and unique adaptability to slurry measurement;
3. Good corrosion and abrasion resistance due to proper selection of sensor lining and electrode materials;
4. The converter has low power consumption and high accuracy;
5. Split and Integrated flow meter, the split electromagnetic flow meter can output 4-20mA current signal for recording, adjustment, and control;
6. Convenient parameter setting, LCD display, can display cumulative flow, instantaneous flow, flow rate, flow percentage, etc.
