Velocity Area (P700 = 4)<br />
The calculation of flow using Velocity Area is only possible when the<br />
“Speedy” velocity sensor is available to provide a signal input proportional<br />
to the velocity of flow and should be installed as detailed in Chapter 3<br />
Speedy Velocity Sensor.<br />
Point of Measurement<br />
The ultrasonic transducer used to measure the level of flow (head) must be<br />
above the maximum head P704 by at least the near blanking distance<br />
P107.<br />
For all Velocity/area applications the point at which the head is measured<br />
should be chosen such that the surface of the liquid is not affected by<br />
turbulence. (See DRWG 10, 11, 12 and 13)<br />
