Badger Meter MS-E1, MS-ER1 Specifications

Pulse Transmitters

Models MS-E1 and MS-ER1

DESCRIPTION

The model MS-E1 is a pulse transmitter designed to be used with
Badger Meter Turbo flow meters and RCDL Disc meters. The pulse
transmitter provides a scaled electrical pulse signal (switch closure
type) for each discrete unit of liquid volume metered. The signal is
used to operate instruments and controls.

Because of the simplicity of this transmitter, maintenance
procedures are minimized. Furthermore, the enclosure provides
watertight protection and is designed to explosion-proof
specifications.

The model MS-ER1 adds a six-digit, non-reset totalizing register
which provides flow totalization in addition to the pulse output.
The mechanical register will totalize under no-power conditions.

OPERATION

Motion of the flow meter measuring element is transferred to the
transmitter by means of an output spindle. The spindle provides
mechanical movement to a gear train designed to rotate a
four-pole permanent magnet. As the magnet turns, the magnetic
field causes a glass-enclosed reed switch to open and close,
generating a pulse output.

By selecting different calculated gear train and driver-to-driven
change gear ratios, a wide variety of pulse output rates
are available.

On the MS-ER1 model, the gear train drive spindle in the
transmitter is geared to the input spindle of the register to totalize
flow. This versatile transmitter/register is available with a wide
choice of pulse rates for measuring in gallons, liters or pounds.

FEATURES

• Operates with direct AC or DC supply

• Glass sealed reed switch, single-pole, single-throw

• Easy recalibration with change gears

APPLICATIONS

The pulse output of the MS-E1 and MS-ER1 pulse transmitters is
used with electromechanical or electronic counters and batch
controllers that do not provide scaling capabilities.

Typical applications include liquid feeding, blending and
batch control.
