SYSTEM DESCRIPTION
The Badger Meter model M2000 electromagnetic flow meter is intended for fluid metering in most industries including water,
wastewater, food and beverage, pharmaceutical and chemical . The meter is intended for the metering of all fluids with electric
conductivity of at least 5 µS/cm (20 µS/cm for demineralized water) . The meter has a high degree of accuracy, and measuring
results are independent of density, temperature and pressure .
The basic components of an electromagnetic flow meter are:
• The
sensor
, which includes the flow tube, isolating liner and measuring electrodes .
• The
transmitter
, which is the electronic device responsible for the signal processing, flow calculation, display and
output signals .

The construction materials of the wetted parts (liner and electrodes) should be appropriate for the intended type of service .
Review all the compatibilities consistent with the specifications .
Each meter is factory tested and calibrated . A calibration certificate is included with each meter .
Measuring Principle
In accordance with Faraday’s induction principle, electric voltage is induced in a conductor moving through a magnetic
field . In the case of electromagnetic flow measurement, the moving conductor is the flowing fluid . Two opposite measuring
electrodes conduct the induced voltage, which is proportional to flow velocity, to the transmitter . Flow volume is calculated
based on pipe diameter .
