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, to use the customers declared maximum flow, 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.
This application is to be assigned to point 1 (Transducer 1).
The distance from the end of the transducer horn (dB Mach 3) to
zero
flow
(
P1-105
) is 40 inches and
max head
(
P71-04
) is 15 inches,
maximum flow
(
P1-705
) is known to be 2.2 Million US Gallons/day.
