FLOWMETERS
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. The low pressure
drop and high pressure rating means oval rotor flow
meters are suitable for both gravity and pump (in line)
applications.
Flow meters are available in either Aluminium or
316 Stainless Steel. Standard rotors are made from
PPS (Polyphenylene
Sulfide
