Sultan Flow Series MANUAL
Draft 1.2, Mar 2009
There are several exponential types of
flow measuring devices. They are:
- BS3680 flumes - BS3680 Weirs
- Area Velocity - Velocity
- Special - Universal
- Linear - Curved
Flow calculations can be performed using
either absolute or ratiometric methods.
The end result will be the same, the
choice of calculation method is limited ac-
cording amount of information available,
with regards to the primary measuring
device.
Ratiometric
For ratiometric calculation it is normally
sufficient to know the maximum flow at
maximum head for the device in question.
All types of primary measuring devices
can be set up with a choice of alarms.
Exponential
If you want to set-up a basic exponential
device, you then need to select the pri-
mary measuring device for your applica-
tion from the following available options:
suppressed rectangular weir, cipolletti
(trapezoidal) weir, venturi flume, parshall
flume, leopold lagco flume, V notch weir
or other, for any other type of exponential
device.
BS3680 Flume
To set-up an application for a BS680
flume, you then need to select the pri -
mary measuring device for your applica-
tion from the following available options:
rectangular flume with or without hump,
U-throated flume with or without hump.
FLOW MEASURING DEVICE SELECTION
BS3680 Weir
To set-up an application for a BS680
weir, you then need to select the primary
measuring device for your application
from the following available options:
rectangular weir, V notch 90 degree, V
notch 5 degree 8 minutes or a Vnotch
28 degree 4 minutes.
Area Velocity
To setup an application for area veloc-
ity, you then need to select the primary
measuring device for your application
from the following available options:
U-channel (circular bottom with straight
sides), rectangular channel, trapezoidal-
channel or a round pipe.
Special Flow Device
To set-up an application for a special
device, you then need to select the pri-
mary measuring device for your applica-
tion from the following available options:
palmer bowlus flume, H-flume or a non
BS680 V-notch.
Universal Device
For devices which do not match any of
the above devices the application can
be setup using a universal flow calcula -
tion, to select this option choose 6. You
then need to select the primary measur-
ing device for your application from the
following available options: linear flow or
curved flow.
