UNIVERSAL AREA X VELOCITY, P3 = 20

Arbitrary area is typically used when the primary element and/or its flow do not fit any

of the primary elements covered by P3. There is no user difference between absolute

and ratiometric calculations P4.

The flow curve is characterized by entering the head (A

even

) and area (A

odd

)

ordinates for the number of data points (n, 4 to 16) over the flow range. The first

point (A0,A1) generally being at 0 head and the last point (A

2n-2

2n-1

) generally being

at maximum head .

‘U’ parameters required * ‘U’ parameters calculated **

U0 = number of data points

(n, 4 to 16)

U1 = area (h)

= head

calculated by OCM-3. May be viewed by accessing ‘U’ parameter.

* The transducer must be above the maximum head by at least the

blanking value, P47.
