3039 / 3040

CT
Calibration Coefficient CF20
- One of the coefficients used to accurately calculate the values measured
by the sensor, defined during the manufacturing process.
Format : Floating Point
Range : -1,000,000 to +1,000,000
Default Value : 0
3041 / 3042
CT
Meter Correction Factor
- A user defined correction factor for adjusting the flow rate reading in situ to
compensate for local process variations.
Format : Floating Point
Range : -100% to +100%
Default Value : 0
3043 / 3044 Pipe Diameter
- This setting is used in conjunction with the volume flow rate to determine
the velocity of the flow through the pipe. By default this is the internal
diameter of the measuring tube of the sensor being used. It can be
changed to determine the velocity of flow through a preceding piece of pipe
work by ent ering t he i nternal di ameter of t hat pi pe w ork. T his v alue i s
scaled in millimetres.
Format : Floating Point
Range : 1 mm to 500 mm
Default Value : Depends Upon Sensor Size (See Appendix D).
3045 / 3046 Measurement Time Constant
- The filtering period used to remove noise from the Mass Flow reading.
Format : Floating Point
Range : 0.2 to 20 seconds
Default Value : 4 seconds
3047 / 3048
CT
Low Flow Threshold
- The flow rate (as a percentage of nominal flow) below w hich t he M ass
Flow reading is automatically set to 0.
Format : Floating Point
Range : 0% to 10%
Default Value : 0.2%
3049 / 3050
CT
User Flow Offset
- A f ixed of fset t hat t he us er c an em ploy t o t est the associated systems.
This value i s s caled ac cording t o t he V alue of t he M ass F low U nits ( see
Holding Register No.1020) . It is reset when a zero calibration is performed
( Output Status Register No. 1002).
Format : Floating Point
Range : -11.945 kg/sec to +11.945 kg/sec.
Default Value : 0 kg/sec
