Z-Plate AWWA Strainers
Bronze and Galvanized Plate Steel
Oval and Round Flanged Ends
Sizes 1 1/2" - 12"
 The strainer
is a vertical Z-plate designed to protect cold water meters from the damaging
effects of debris and foreign matter. The strainer improves the velocity
profile of the water being metered and minimizes the effects of velocity
distortion caused by upstream valves and fittings. Consequently, the meter's
accuracy is maximized by the elimination of debris and turbulence.
Compliance to Standards.
The Z-plate strainer complies with
all material and design requirements of the American Water Works Association
Standards C701 and C702 as most recently revised.
Installation.
The strainer should be installed
immediately upstream from the meter it is protecting. It is preferable that the
strainer is installed with the removable top plate vertically accessible for
underpressure flushing and maintenance.
Application.
The Strainer is recommended for
use with the T-3000 and C-3000 meters. Its application ahead of these meters
will maximize revenue and extend the life of the measuring element. The strainer
for use with POTABLE COLD WATER up to 120F (50C) and working pressures up to
150 psi. Working pressure tests are made before shipment. No adjustments are
needed to be made before installation.
