The option enables you to access the more advanced features
of the DF868. In this option you can perform five functions:
•
calculate the kinematic viscosity (KV) based on signal strength
(SS), or activate temperature compensation by applying a
temperature vs. viscosity table (see below)
•
enter a table of K-factors (based on velocity or Reynolds number)
that compensates for non-linear flow rates (see the next page)
•
enable mass flow (calculated for static fluid density) (page 1-41)
•
select the size of the transducer transmission signal (page 1-41)
•
actively compensate for widely varying signal delays
SETUP
1. At the window, press
[F1]-[F4]
2. Use the and [←] and [→] keys to select the desired
option.
Use the KVTab option to calculate the kinematic viscosity (KV)
based on signal strength (SS) or temperature. To use this option, you
must select either a static KV value (entered at the
PIPE
prompt in the submenu), a table of KV/SS values (entered in the
KV/SS
submenu, discussed on page 1-54), or a table of temperature vs.
viscosity values (entered in the
55).
