ST100L In-line Flow Tube
Flow element is threaded and keyed in an in-line flow tube, calibrat-
ed and supplied as a spool-piece; options include low flow injection
tubes and built-in Vortab flow conditioners for optimum low flow
rangeability and performance

flanges, or butt weld prepared
Option: Flanges sized for flow tube
Remote Transmitter Configurations: Transmitter may be
mounted remotely from flow element using interconnecting cable
(up to 1000’ [300 m])
STP Models: Additional Specifications on Pressure Sensor

Outputs
Analog
Standard: Three (3) 4-20 mA*, 0-1kHz, or 0-10 kHz pulse/frequency
4-20 mA outputs are user assignable to flow rate, temperature
and/or if so equipped, pressure; outputs are user programmable to
full flow range or subsets of full flow range; pulse/frequency output
is user selectable as pulse for external counter/flow totalizer, or as
0-1 kHz or 0-10 kHz frequency representing flow rate
* Outputs are isolated and have fault indication per NAMUR NE43
guidelines, user selectable for high (>21.0 mA) or low (<3.6 mA)
Optional: Standard output plus two (2) 2A SPDT relays
Relays independently user assignable to flow, temperature or
pressure; user programmable for hi/lo trip, hysteresis from 00.0 to
99.9 counts and time delay from 00.0 to 99.9 seconds
Digital
Standard: USB, Ethernet
Optional: HART (comes standard with analog outputs, V7 compliant
F
oundation
fieldbus H1, PROFIBUS PA or Modbus RS-485
Auxiliary Inputs
Two 4-20 mA input channels; used for FCI administered special
configurations to allow ST100 Series to accept inputs from external
devices such as gas analyzers, gas composition or pressure sensors
