AWWA
Standard
The Model SW500 Main Line NSF Certified Propeller Flowmeter
is manufactured to comply with applicable provisions
of AWWA Standard No. C-704-92 for propeller-type flowmeters.
Tube
The Model SW500 is designed for a maximum continuous
working pressure of up to 150 PSI and is fitted with
AWWA Class D flanges. The Model SZ500 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.
Register
As with all McCrometer propeller flowmeters, standard
features include and instantaneous flowrate indicator
and straight reading, six-digit totalizer.
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
SW500/SZ500 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.
Magnetic
Drive
As with all McCrometer propeller flowmeters, standard
features include a magnetically coupled drive.
