6.5 General Configuration
PV Type
Selecting PVs for
Broadcast
The PV Type field is found on the General tab card.
Select one of the PV Types in Table 10 to choose which of the
transmitter’s PVs are to be sent (broadcast) to the control system.
Optionally, you can select whether the secondary variable (SV1) is
included as part of the broadcast message. The secondary is the SMV
transmitter’s meter body temperature.
NOTE: This configuration parameter is valid only when the transmitter is in DE mode.

with the Secondary Variable (SV1).
PV1 (DP) w/SV1 & PV2 (SP) Differential Pressure (PV1) and
Static Pressure* (PV2) measurements with
the Secondary Variable (SV1).
PV1 (DP) w/SV1 - PV3 (TEMP) Differential Pressure (PV1),
Static Pressure* (PV2) and
Process Temperature (PV3) measurements
with the Secondary Variable (SV1).
PV1 (DP) w/SV1 - PV4 (FLOW) Differential Pressure (PV1),

and the Calculated flow rate value (PV4) with
the Secondary variable (SV1).
* Static pressure may be absolute or gauge pressure, depending on the SMV model
type. (For models SMA110 and SMA125, PV2 measures absolute pressure. For
model SMG170, PV2 measures gauge pressure.)
