Notes:
4. When operating on 1cP liquids the meters may be used up to the nominal (3cP) maximum flow rate rating
for intermittent periods only.
5. For applications above 500cP the maximum flowrate must be reduced according to the table above, for
applications above 1000cP the maximum flow rate must be reduced further in order to limit the maximum
pressure drop across the meter to below 1Bar (14.5psi). Consult the manufacturer if you are unsure.
6. Filtration requirements are for soft particles only; hard particles of any size are not acceptable.
