Figure F-5. Cylindrical or spherical tank cross-section
F.3.13 Flow measurement
Table F-1 on page 119 lists the Tank Shape/Non-Linear Profile (P011) options that select a
standard flow structure profile and the conversion (scale) factors used to calculate a flow
process value (PV).
Tank Shape/NLP (P011) = “Special Plot”
The “Special Plot” option is used for irregular-shaped flow profiles.
See page 112 for a full description.
Tank Shape/NLP (P011) = “Flume/Weir-3/2”
This setting is applicable when flow rate measurements are needed from an open channel with a
flume or weir profile (see Figure F-6 on page 117).
The rate of flow per second is calculated by:
Q = k x h
Pwr
Where ‘h’ is the live liquid level, ‘Q’ is flow rate per second, ‘Pwr’ is the power factor and ‘k’ is a
user-entered scale factor.
The transmitter automatically populates parameter Power Factor / Profile Height (page 122)
with a power factor from Table F-1 on page 119.
