Volumetric flow
The following fields are used to configure the frequency or current outputs selected to
output a volumetric flow rate. The fields are only enabled if the associated output’s Content
is set to Uncorrected (Actual) or Corrected (Standard).
Full scale volumetric flow rate used with output:
Enter the flow rate to be equivalent to the maximum frequency of the frequency output.
For Daniel Mark III Ultrasonic Gas Flow Meters, each frequency output has its own register.
This property is disabled if Frequency outputs was cleared on the Startup Page.
K-factor:
A read-only value showing the calculated K-factor from the Full scale volumetric flow rate
used with frequency outputs and the Maximum frequency for frequency output. This
property is disabled if Frequency outputs was cleared on the Startup Page.
Vol/pulse:
A read-only value showing the calculated inverse of the K-factor. This property is disabled if
Frequency outputs was cleared on the Startup Page.
Velocity
Maximum scale velocity used with output:
Enter the velocity to be equivalent to the maximum frequency of the frequency output.
These values are only enabled for Daniel Mark III Ultrasonic Gas Flow Meters and if the
Content is set to Average flow velocity or Average sound velocity. This property is disabled if
Frequency outputs was cleared on the Startup Page.
Minimum scale velocity used with output:
Enter the velocity to be equivalent to the minimum frequency (i.e. 0Hz) of the frequency
output. These values are only enabled for Daniel Mark III Ultrasonic Gas Flow Meters and if
the Content is set to Average flow velocity or Average sound velocity. This property is
disabled if Frequency outputs was cleared on the Startup Page.
