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. Ratiometric
calculation will be used, there is no requirement for alarms and the flow rate
is to be displayed in litres/second. The totaliser is to record the flow in cubic
metres but is not to be displayed during RUN.
The distance from the end of the transducer horn (dB Mach 3) to zero flow
(P105) is 1 metre and max head (P704) is 0.4 metres, maximum
flow(P705) is known to be 96.5 litres/second.
