Operation. The C700 is an oscillating piston style,
positive displacement water meter. The product
utilizes a piston that water use rotates in a measuring chamber, each piston revolution being equivalent to a known volume of water. The piston
movement is transferred by a magnetic drive to a
straight reading sealed register which contains the
appropriate reduction gearing.

Installation. The meter must be installed in a clean
pipeline, free from any foreign materials. Install the
meter with direction of flow as indicated by the
arrow cast in the meter case. The meter may be
installed in horizontal, vertical or inclined lines, with
register facing upward.

Application. The meter is for use only with
POTABLE COLD WATER up to 120°F (50°C) and working pressures up to 150 psi. The meter will register
between 98.5% and 101.5% at normal and high
flows and between 97% and 101% at the AWWA
specified low flow. Accuracy tests are made before
shipment, so no adjustments need to be made
before installation.
Construction. The meter consists of a straight
through-flow main case, dual inlet measuring
Maintenance. The measuring chamber
assembly can be removed, repaired or
replaced. Pretested measuring chamber
assemblies are available for exchange or purchase, and spare parts are available from our
central warehouse or designated regional
locations. Elster AMCO Water staffs and operates a repair facility at its U.S. manufacturing
plant in Ocala, Florida.
Pulser Type “BI”. The “BI” pulser is a limit
switch device which requires power from an
external source (2 wire). Contact closure: 1
contact = 1 USG. The switch is rated to 3 amps
at 125 VAC max. Note: Register housing and
register are 3½ in. diameter style. For full details see specification sheet INDC7-PUL-001.
Pulser Type “SFI”. The “SFI” pulser is a solid state device which requries 6-24 VDC from an external
source (3 wire). Note: Register housing and register are 3½ in. diameter style.

chamber, vertically grooved oscillating piston, high
capacity strainer, removable bottom plate, full rubber liner, body bolts with integral washers and a
magnetically driven register. The main case is cast
in bronze with raised characters designating
model, size and direction of flow. Maincase bottom
plates are available in a choice of polymer, waterworks or low-lead bronze or, if frost protection is
desired, in cast iron. The 2-piece snap-fit measuring
chamber is of a top and bottom inlet, side output
design and features a unique self-flushing sediment well. Other features include a removable,
contoured division plate, captive drive bar and high
torque magnet complete with a nylon bushing. The
flow-stream balanced piston has a unique thrust
bearing insert and features a Turbulence Seal™
system which passes debris while sustaining the
most linear accuracy curve in the industry. Each
register is secured to the main case with a tamperproof plug to eliminate tampering.
Direct Read Register. The register is contained
within a 90% copper seamless can which is ovencured at 150°F for 90 minutes to eliminate condensation. The 5 mm true tempered glass lens is
secured with an "L" shaped gasket, then roll sealed
to produce a permanently sealed design. To assure
easy reading, the totalizer wheels are large and
color coded. The applicable size, model, registration, part number and date code are printed on the
calibrated dial face. Moving clockwise during operation, the extra-thin center sweep hand does not
interfere with meter reading, and the 1:1 piston ratio
low-flow indicator gives visual indication of plumbing leaks. For accurate meter testing, 100 clear
graduations appear at the register’s circumference.

Magnetic Drive. The magnetic drive design facilitates coupling between the measuring chamber
and the external register. The coupling is absolute at all rated flows.
Connections. Meter casing spuds have external straight threads conforming to ANSI B.1.20.1.
Bronze coupling nuts and tailpieces are available. Tailpieces have external taper pipe threads conforming to ANSI B.1.20.1. Their lengths and thread sizes are as specified by AWWA Standards.
