The battery-powered electromagnetic flow meter converter adopts internal battery power supply without external power supply. It is suitable for working conditions where the field power grid cannot be reached and the power grid is difficult to lay. It is especially suitable for the monitoring, metering and settlement of the tap water supply system. The battery-powered electromagnetic flow meter converter adopts ultra-low power circuit technology to design efficient and reliable excitation and signal processing circuits to achieve measurement functions to ensure that the converter has high reliability and stability. At the same time, it adopts highly efficient system management technology. The system power consumption is reduced, power supply cost is saved, and accurate measurement is realized at the same time.
Mag meter works based on Faraday’s law, when the liquid goes through the pipe at the flow rate of v with a diameter D, within which a magnetic flux density of B is created by an exciting coil, the following electromotive E is generated in proportion to flow speed v:
E=K×B×V×D
Where:
E－Induced electromotive force
K－Meter constant
B－Magnetic induction density
V－Average flow speed in cross-section of measuring tube
D－Inner diameter of measuring tube
The sensor uses the induced potential E as a flow signal and transmits it to the converter. After a series of digital processing by amplifying, transforming and filtering, the instantaneous flow and cumulative flow are displayed by a dot matrix liquid crystal with backlight.
