Velocity Area
The calculation of flow using Velocity Area is only possible when the
optional current input is available to provide an input from a velocity
sensing device which provides a signal proportional to flow. (Please consult
Pulsar for availability).
Point of Measurement
The transducer must be above the maximum head P704 by at least the near
blanking distance P107.
For all Velocity/area applications the point at which the head is measured
should be chosen such that the surface of the liquid is not affected by
turbulence. (See DRWG 10, 11, 12 and 13)
