Type
Description
FlowValueF Inst actual flow value as float in FlowUnit
FlowValueI Inst actual flow value as int (in 10E-4 steps) in FlowUnit
FlowUnit Inst
recalculate FlowUnit of CalTable to User defined FlowUnit
[SCCM, SLM, SCCH, SLH, SCMM, SCMH, SCFM, SCFH, %, ‰, PPM, PPC,
PPT, PPQ, V, DEFAULT]
FullScale Inst
full scale is calculated from Parameter CalConv=>FullScale and
Meter=>FlowUnit.
GCF Inst global GCF; default = 1.0
EnGCF Inst enable global GCF [0 = disabled, 1 = enabled]
ZeroGain Inst for autozero ZeroGain
ZeroOffset Inst for autozero, -5% .. +5% of full scale
EnAutoZero Inst enable Autozero ZeroOffset and ZeroGain [0,1]; default = 1
AutoZero Inst
0 to 1 transition activates zeroing if (VALVE_OVERRIDE==FLOW_OFF &&
FLOW_SETPOINT < 5%FS)
UserSpan Inst set global user span
UserZero Inst set global user zero
Overflow Inst TBD
Underflow Inst TBD
TotalFlow Inst
Totalized Flow of Meter Object in FlowUnit (in 10E-1 steps) i.e. min. 298 days for
a 500 range
EnableTotalizer Inst enable the totalizer function
ResetTotalizer Inst 0 to 1 transition resets totalizer to zero
SetDefault Func Reset object to default values
Autozero Func
if read or write, execute Autozero if (VALVE_OVERRIDE==FLOW_OFF &&
FLOW_SETPOINT < 5%FS)
ResetAutozero Func if read or write, clear Autozero
Wink Func if read or write, execute WinkStatus
ResetTotalizer Func if read or write, reset the TotalFlow value to 0

Config Inst
[controller, meter, direct]
controller => Valve controls the flow
meter => Valve full open
direct => Valve is controlled with the setpoint from 0% to 100%
