M0300SW Reverse Strap-on Saddle Flow Meter

DESCRIPTION

The M0300SW is a strap-on reverse-helix*
propeller meter designed to shed debris often
associated with surface water applications.
This flow meter is designed with the meter body
turned 180 degrees from normal, a propeller
installed nose-first on the bearing shaft, and
a reverse flow style bearing assembly. This
configuration allows the ell to curve with the
flow, allowing grass or other debris to shed off
with ease. The assembly design also reduces
the ability of sand and silt to accumulate in the
bearing.

All Mc Propeller flow meters are manufactured
to comply with applicable provisions of AWWA
Standard No. C704-02 for propeller-type flow
meters.
