INATEC – LDG Battery Powered Electromagnetic Flowmeter

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.

Characteristics

Diameter : DN 03 – DN 2100.

Accuracy : 0.5 %.

Environmental temperature : – 20℃ ~ 50℃.

Ingress protection : IP65, IP68 (Optional)

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
