STP102AA, STP112A, Process Connections and Insertion
Lengths
Compression Fittings: Models ST100A and ST102AA only
¾" or 1" male NPT, stainless steel with adjustable Teflon
ferrule or metal ferrule; or flanged tapped and threaded for ¾"
fitting, ANSI or DIN flanges.
Compression fittings not available with 850 °F [454 °C]
temperature versions of ST100A or ST102AA.
Retractable Packing Glands
Low pressure 50 psig [3,5 bar(g)] or medium pressure 500 psig
[34 bar(g)] with graphite or Teflon packing material; 1¼" male
NPT or ANSI or DIN flange.
Teflon packing required when process media is ozone, chlorine
or bromine. Remote mount required when medium pressure
packing gland is required.
Fixed Fittings / All Welded
1" male NPT, ANSI or DIN flange
Insertion Length
Field adjustable lengths:
1" to 6" [25 mm to 152 mm]
1" to 12" [25 mm to 305 mm]
1" to 21" [25 mm to 533 mm]
1" to 36" [25 mm to 914 mm]
1" to 60" [25 mm to 1524 mm]
Fixed lengths from 2.6" to 60" [66 mm to 1524 mm]
■ ST100AL In-line Flow Body and Process Connections
Flow element is calibrated 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
Size: 1" diameter tubing; 1”, 1½" or 2" Schedule 40 pipe;
1" Schedule 80 pipe
Length: 9 nominal diameters
Process Connections: female NPT, male NPT, ANSI or DIN
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 ft [300 m]). Remote configuration
required with selection of medium pressure packing gland.
