Special Devices (P700 = 5)<br />
Point of Measurement<br />
The transducer must be above the maximum head P704 by at least the near<br />
blanking distance P107.<br />
In the case of a Palmer Bowlus flume the point of head measurement<br />
should be half the value of Dim “A” P710 upstream of the device.<br />
For an H-Flume the head measurement is taken at a point downstream<br />
from the flume entrance as detailed in the table below:<br />
