Remove Device from the Pipeline
If the device has been operated with toxic, caustic, flammable or water-endangering products, check and make sure, by
rinsing or neutralizing if necessary, that all cavities are free from such dangerous substances before you remove the device.
RoHs
The M1000 meter is RoHs compliant.
SYSTEM DESCRIPTION
The Badger Meter M-Series® Model M1000 electromagnetic flow meter is intended for fluid metering in most industries
including water, wastewater, food and beverage, pharmaceutical and chemical.
The basic components of an electromagnetic flow meter are:
• The detector, which includes the flow tube, isolating liner and measuring electrodes.
• The amplifier, 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 specifications on the
intended type of service. We recommend that you review all of the compatibilities consistent with the specifications.
Each meter is factory tested and calibrated. A calibration certificate is included with each meter.
WARNING
CONSULT THE INSTALLATION INSTRUCTIONS BEFORE DETERMINING THE TEMPERATURE RATING OF THE CABLE.

IMPORTANT
Wire connections must meet or exceed a temperature rating of 176° F (80° C).
Measuring Principle
In accordance with Faraday's induction principle, electric voltage is induced in a conductor moving through a magnetic
field. In electromagnetic flow measurement, the moving conductor is replaced by the flowing fluid. Two opposite measuring
electrodes conduct the induced voltage, which is proportional to flow velocity to the amplifier. Flow volume is calculated
based on pipe diameter.
