Model EC-A
GENERAL
Badger Meter's Electric Contacting Register, Model EC-A, is
used on Disc and Turbo meters to provide an electric pulse
output for a given quantity of liquid metered. In a typical application, the pulses would be transmitted to a chemical feed
pump for boiler makeup water or for cooling towers.
The top portion of the EC-A unit consists of a register with
a nonresettable totalizer. This register is mounted on top of
the contactor section which consists of a gear train assembly,
cam-operated switch and appropriate change gears.
The contact rates of the EC-A accessory can be adjusted in
the field with the use of change gears and/or different gear
train assemblies.
The register can be indicating one unit of measure while the
contact rate is supplied in a different unit of measure. For
example, gallons and cubic feet.

OPERATION
Water or other liquid flowing through the meter will cause the
cam in the contactor section to rotate. The cam operates a
single-pole, double-throw (SPDT) switch. When connected
to a suitable power supply, the EC-A register will provide a
pulse output corresponding to a predetermined quantity of
liquid. The pulse rates range is from 10 gallons to 10,000 gallons per contact, depending on the meter size. If desired, the
pulses can be used to actuate a relay which, in turn, would
operate other equipment.
