ST100AL In-Line Process Connection
The in-line ST100AL flow element assembly can be threaded, flanged or butt weld mounted to the process piping. The specific type in-line process
connection is customer-specified on the order information sheet (OIS). See Figure 9 below.
Mount the sensor to the process piping per the application piping requirements. Verify the flow direction arrow is pointed in the correct direction. After
the sensor head has been located correctly and tightened into place, verify the process seal does not leak by slowly applying pressure until the
normal operation pressure is applied. Check for leaks at the process connection boundary.

Flow Transmitter Electronics Installation
The instrument electronic transmitter can be an integral part of the flow element or it can be mounted remotely using a shielded cable between the
flow element and the electronics.
Use power wiring with a minimum 90 °C rating.
ESD Precautions
Caution:
FCI flow meters contain static-sensitive devices. To avoid damage to the instrument observe the ESD precautions
listed below before opening the instrument for wiring.
● Use a wrist band or heel strap with a 1 MΩ resistor connected to ground.
● Use a static conductive mat on the work table or floor with a 1 MΩ resistor connected to the ground when working on the instr ument in
a shop setting.
● Connect the instrument to ground.
● Apply antistatic agents such as Static Free made by Chemtronics to hand tools used on the instrument.
● Keep high static-producing items away from the instrument.
The above precautions are minimum requirements. The complete use of ESD precautions can be found in the U.S. Department of Defense
Handbook 263.
