Example 1 ‘V’ Notch Weir
In this example it is required to calculate the flow through a Simple
Exponential Device, which on this occasion is a V-Notch Weir. The K factor
for the weir is unknown so ratiometric calculation will be used, there is no
requirement for alarms and the flow rate is to be displayed in Mil USG/day.
The totaliser is to record the flow in 1000’s USG but is not to be displayed
during RUN. The transducer to be used is a dB3.
The distance from the face of the transducer to zero flow ( P105 ) is 40
inches and max head ( P704 ) is 15 inches, maximum flow ( P705 ) is known
to be 2.2 million US gallons/day.
