A.5 Configuration, Continued

SENSRTYP Parameter The default sensor type for a given SMV 3000 transmitter PV is listed in Table A-4.

Table A-4 Sensor Type Selections for SMV 3000 PVs

IF Process Variable Number is…

PV1

PV2

PV3

PV4

THEN SENSRTYP is …

SPT_DP

SPT_AP *

STT

SFM

* Use SPT_AP if PV2 is measuring absolute pressure or gauge pressure.

ATTENTION

When using an SMV Model SMG170, the SENSRTYP parameter for PV2 may be set to SPT_AP, but will display a gauge pressure value that may be negative.

PVCHAR Parameter

The PV characterization selection for each SMV transmitter PV can be as

 

listed in Table A-5.

 

Table A-5

PV Characterization Selections for SMV 3000 PVs

IF Process Variable Number is…

PV1

PV2

PV3

PV4

THEN PVCHAR can be …

LINEAR or SQUARE ROOT *

LINEAR only.

LINEAR only.

LINEAR/N/A †

 

* Does not affect PV4 flow calculation.

 

Linear is shown on detail display, but it has no meaning.

STI_EU Parameter

 

Select any valid Engineering Unit (EU) for PV1, PV2, and PV3, so that the

 

values displayed for URL, LRL, URV, and LRV on the Detail Display will

 

be converted to the selected EU. There is no check for mismatch of EUs,

 

since the transmitter sends these values as a percent of Upper Range Limit

 

so the value is the same regardless of EU.

 

NOTE: You can only select BLANK or CM_HR as EU for PV4. Keep in

 

mind, that the URL, LRL, URV, and LRV are displayed in “base”

 

units of tonnes per hour (t/h) or cubic meters per hour (m3/h) as

 

applicable.
