SP4000 Flow Computer
The DP-Factor (K
DP
) can be entered manually or the flow computer
can compute it for you. The information necessary for this calculation
can be found on the sizing sheet from a flowmeter sizing program.
Note:
The following data must be entered before the flow computer can
compute the DP-Factor.
1. Flow equation see "SYSTEM PARAMETER"
2. Fluid Data see "FLUID DATA"
3. Beta see "FLOW INPUT"
4. Meter expansion coef. ref see "FLOW INPUT"
5. STP Ref. temperature*, pressure see "OTHER INPUT"
7. Inlet Pipe Bore
see "FLOW INPUT"
8. Calibration Temp. see "OTHER INPUT"
* only for gas flow equations.
