INSTRUCTION MANUAL
This Flow Meter has incorporated the oval rotor
principal into its design. This has proven to be a
reliable and highly accurate method of measuring
flow.
Exceptional repeatability and high accuracy over a
wide range of fluid viscosities and flow rates are
features of the oval rotor design. With a low pressure
drop and high pressure rating oval rotor flow meters
are suitable for both gravity and pump (in line)
applications.
