The Smith Meter® Model E4 Meter is a doublecase, straight-through positive displacement meter.
It incorporates 4-inch ANSI flanges and should be
applied in flow systems that handle rates typical of
3-inch systems, but have 4-inch piping due to pumps
and pressure loss considerations. Applications include:
blending, batching, dispensing, inventory control, and
custody transfer. The relatively high intermittent rating
is for use on systems that would require this flow rate
infrequently.
» Superior Accuracy – The Smith Meter® Rotary
Vane meter principle, combined with the
meter’s uniquely designed (offset) inlet and
outlet nozzles, minimizes pressure drop across
the measuring chamber, which reduces
flow through meter clearances to maximize
accuracy.
» Low Pressure Drop – Streamlined flow path
provides low pressure drop.
» Positive and Accurate Registration – High
torque drive calibrator with adjustment
in 0.05% increments ensures accurate
registration.
» Long Service Life – Low friction ball
bearings, fixed cam-type timing, and rugged
construction give sustained accuracy and long
service life.
