Flow Element Wiring
The ST/STP102A can be configured with one integral and one remote flow element or with two separate flow elements and remote electron-
ics. Wiring diagrams for these configurations are located in Appendix B. Each of the flow elements on the ST102A/STP102A are connected to
the transmitter using an 8-conductor shielded cable as specified in the
Instrument Wiring Table 1
.
ST/STP102A Electronics Description
The electronic transmitter for the ST/STP102A type instruments provides a two point averaged flow and temperature output on the display
and the customer selected output mode, analog or digital.
Analog 4-20mA output: factory default setup
• Output #1 – Two point average Flow
• Output #2 – Two point average Temperature
• Output #3 – Pressure, available on STP models
