Measurements - DANIEL 2234 Manual

__________________________ MODEL 2234 DIGITAL FLOW COMPUTER
C. Static Pressure Transducer Full Scale (PFS) - Read Code 9
Static Pressure Transducer Zero (PZ) - Read Code 10
Full scale and zero pressure values, used by the computer to scale
input signals from the pressure transducer, are displayed by using
Read Codes 9 and 10. Pressure is displayed in PSIA.
D. Line Differential Pressure Full Scale (HFn) - Read Code 23n
The full scale line differential pressure, used by the computer to scale
pressure differential in line number (n), is displayed by using Read
Code 23n. Pressure is displayed in inches of water. FXD values
greater than zero are acceptable.
Refer to Field Wiring Diagram, DE-9144, for the definition of the
transducer per configuration selected.

3.6.2 MEASUREMENTS

Read Codes for measurements display measured input values used by the computer
in calculation of the flow rates and flow totals. Measurements are displayed as
VAR values. The values may be changed to a FXD value by the operator. Refer
to paragraph 3.5.2.
A. Measured Density (DEN) - Read Code 0
The measured specific density value, used by the computer to calculate flow rates
and flow totals in accordance with API-2565, is displayed by using Read Code 0.
The density is displayed in pounds per cubic foot (LBF3). FXD values greater than
0.1 are acceptable.
