SECONDARY_VALUE parameter
This parameter makes available to the AI block the temperature value of the ST100. There are two valid engineering units associated with
this parameter, ºC and ºF
TERTIARY_VALUE parameter
This parameter makes available to the AI block the Totalizer value of the ST100. This is an optional parameter that can be turned “ON” or
“OFF”. It is associated with the volumetric flow and the mass flow. The units are set by the flow units selected.
QUATERNARY_VALUE parameter
This parameter makes available to the AI block the pressure value of the ST100. This is an optional parameter that can be activated when A
flow sensor is connected to the ST100. The engineering units associated with this variable are PSIG, in H2Og, bar (g), Kpa(g), cm H2O g, in Hg
, KpaA, mm Hg.
Engineering units can be viewed through this block.
