Electromagnetic flowmeter is the first choice for corrosive liquid flowmeter, which is used to measure the flow of strong corrosive liquids such as acid, alkali, and salt solution.
According to the pH value, temperature and concentration of the liquid, the appropriate lining material and electrode material are selected.
The working principle of electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. The conductive medium in the measuring tube is equivalent to the conductive metal rod in the Faraday test, and the two electromagnetic coils at the upper and lower ends generate a constant magnetic field. When a conductive medium flows, an induced voltage is generated. Two electrodes inside the pipe measure the induced voltage generated. The measuring tube is electromagnetically isolated from the fluid and the measuring electrode by means of a non-conductive lining (rubber, Teflon, etc.).
1. There are no moving parts and no blocking parts in the pipeline of the electromagnetic flowmeter, and there is almost no additional pressure loss in the measurement.
2. The measurement results have nothing to do with physical parameters such as flow velocity distribution, fluid pressure, temperature, density, and viscosity.
3. The range can be modified online according to the actual needs of the user on site.
4. High-definition backlit LCD display, full Chinese menu operation, easy to use, simple to operate, easy to learn and understand.
5. Adopt SMD devices and surface mount (SMT circuit has high reliability.
6. Adopt 16-bit embedded microprocessor, fast operation speed, high precision, programmable frequency low-frequency rectangular wave excitation, which improves the stability of flow measurement and low power consumption.
7. Full digital processing, strong anti-interference ability, reliable measurement, high precision, flow measurement range up to 150:1
8. Ultra-low EMI switching power supply, using a wide range of power supply voltage changes, good EMC resistance
9. There are three totalizers inside, which can display the forward accumulated amount and the difference accumulated amount respectively. There is a non-power-off clock inside, which can record 16 times of power-off time.
10. With RS485, 4-20MA output, pulse output and Hart (optional) and other digital communication signal output.
▲It has the function of self-inspection and self-discipline
