Features
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 the meter clearances to maxi-
mize 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.
Model C2-S1 with Large Numeral Counter and Ticket
Long Service Life – Low friction ball bearings, fixed Printer
cam-type timing, and rugged construction give sus-
tained accuracy and long service life.
