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

V-notch angle weirs, the head is measured upstream of the weir plate at a
minimum distance of 3 times maximum head to ensure the surface of the
liquid is not effected by turbulence or drawdown. See Exponential devices,
above, for further details.
