AWWA
Standard
Manufactured to comply with applicable provisions
of AWWA Standard No. C-704-91 for propeller-type
flowmeters.
Tube
The Model MW500 is designed for a maximum continuous
working pressure of up to 150 PSI and is fitted
with AWWA Class D flanges. The Model MZ500 is
designed for a continuous working pressure of
up to 300 PSI and is fitted with ANSI B16.5 Class
300 flanges. The meter flow tubes are coated with
fusion-bonded epoxy for maximum corrosion protection
and integral flow straightening vanes reduce upstream
flow turbulence.
Magnetic
Drive
As with all McCrometer propeller flowmeters, standard
features include a magnetically coupled drive.
Impeller
Manufactured of high-impact plastic, capable of
retaining their shape and accuracy over the life
of the meter. Each impeller is individually calibrated
at the factory to accommodate the use of any standard
McCrometer register, and since no change gears
are used, the MW500/MZ500 can be field-serviced
without the need for factory recalibration.

Bearings
Factory lubricated, stainless steel bearings are
used to support the impeller shaft. The shielded
bearing design limits the entry of materials and
fluids into the bearing chamber providing maximum
bearing protection.
Register
The instantaneous flowrate indicator is standard
and available in gallons per minute, Acre Feet,
Acre Inches, Cubic Meters and other units. The
register is driven by a flexible steel cable encased
within a protective vinyl liner. The register
housing protects both the register and cable drive
system from moisture while allowing clear reading
of the flowrate indicator and totalizer.
Installation
Standard installation is horizontal mount. If
the meter is to be mounted in the vertical position,
please advise the factory. A straight run of full
pipe the length of five(5) diameters ahead and
one(1) diameter behind the meter is the minimum
normally recommended.
Register
As with all McCrometer propeller flowmeters, standard
features include and instantaneous flowrate indicator
and straight reading, six-digit totalizer.
