MEJ-LDG Electromagnetic meters are a leading choice to deliver the performance and precision your applications require. These meters are applicable for all conductive liquids, such as water, acids, alkalis, slurries and many others. Typical applications are monitoring of liquids, filling, dosing and precise measurement in custody transfer.
Characteristics
Pipe diameter: DN15~DN1000
Accuracy: ±0.5%(Flow speed > 1m/s)
Theoretical value: Water: Min. 20μS/cm; Other liquid: Min. 5μS/cm
Recommended value: ＞30μS/cm
Turndown ratio: 1:100
Power supply: 100-240VAC，50/60Hz; 22-26VDC
Minimal Maintainice. Has no moving parts or flow obstructiions, which virtually eliminates maintenance and pressure drops
Measuring principle:
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
