Example 2 BS3680 U-Throated Flume<br />
In this example it is required to calculate to BS3680 the flow through a U-<br />
Throated Flume without any hump. Absolute calculation will be used, and<br />
there is a requirement for an alarm to indicate a low flow condition which<br />
will be set to relay 1. The flow rate is to be displayed in cubic meters/hour<br />
and the totaliser is also to record the flow in cubic metres, the resettable<br />
totaliser is to be displayed during RUN.<br />
The distance from the face of the lower transducer (DUET) to zero flow<br />
(P105) is 1 metre and max head (P704) is 0.4 metres, maximum<br />
flow(P705)<br />
The dimensions of the flume are as follows:<br />
Approach Channel diameter (Dim “A”) P710 = 0.7 m<br />
Throat diameter (Dim “B”) P711<br />
= 0.5 m<br />
Throat length (Dim “C”) P712<br />
= 1.0 m<br />
