Badger M-Series

Model M-2000 Amplifi er

Mag Meter

GENERAL

The innovative design of the Badger® M-Series® mag meter
model M-2000 amplifi er represents the next generation
of electromagnetic (mag) fl ow meter signal processing.
Incorporating the latest developments in microprocessor
signal conditioning, the advanced design of the M-2000
meter allows for an accuracy of ±0.25 percent with a flow
range of 300:1. The M-2000 amplifier can be integrally
mounted to the detector or can be mounted remotely, if
necessary. Housed in a NEMA 4X (IP66) enclosure, the
amplifier targets a variety of applications and is well suited
for the diverse water and wastewater treatment industry.

OPERATION

The M-2000 amplifi er receives the detector's analog signal,
amplifi es that signal and converts it into digital information.
At the processor level, the signal is analyzed through a
series of sophisticated software algorithms. After separating
the signal from electrical noise, it is converted into both
analog and digital signals that are used to display rate of
fl ow and totalization. In addition, the processor controls
zero-fl ow stability, analog and frequency outputs, serial
communications and a variety of other parameters. The large
four-line, 20-character LCD display indicates rate of fl ow,
forward and reverse totalizers and diagnostic messages. The
display also serves to guide the user in simple terms through
the user-friendly programmable routines.

Programmable parameters of the amplifi er include, but
are not limited to: calibration factors, totalizer resets,
unit of measure, analog and pulse output scaling, fl ow-
alarm functions, language selection, low-fl ow cutoff, noise
dampening factor and excitation frequency selection.

APPLICATION

The M-2000 amplifi er's main function is to detect and
condition fl ow information from the electromagnetic detector.
The unit is ideally suited for measuring dynamic, non­continuous fl ow. In applications where a minimum and/
or max imum fl ow rate must be tracked and monitored, the
unit provides pulse signals that can be fed to dedicated
batch controllers, PLCs and other more specialized
instrumentation.
