B.1 Miscellaneous conversion factors
Use the following calculations:
• 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.

*TimeUnit: Time conversion factor depends on the VolFlowRate
• volume/second = 1 s/s
• volume/minute = 60 s/m
• volume/hour = 3600 s/h
• volume/day = 86400 s/d
