Pre-Installation
Serial Number Alignment
The ST75 and ST75V (Vortab) can be specified with integral or remote electronics. The flow element has a serial number etched
into the side of the HEX as shown on Figure A. In addition, the enclosure tag also shows serial and model numbers. The associated
transmitter circuit card has a serial number noted on the board as shown in Figure B. The flow sensor and transmitter circuit have been
calibrated as a matched set and should be paired together in service unless otherwise approved by a factory technician.
Flow Direction Alignment
All sensor elements have a flow arrow indicator marked on the element assembly at the reference HEX flat. These flow elements have
been calibrated in a particular direction and are designed to be used in service with the flow arrow going in the same direction as flow in
the pipe stream. The flow element has been calibrated directly in the pipe tee or tube tee with careful consideration for orientation and
insertion depth. Removal from the tee section while physically possible is not recommended unless authorized by a factory technician.

Recommended Straight Run
To optimize flow meter system performance, FCI recommends installation with a minimum of 20 diameters upstream straight run and 10 pipe
diameters of downstream straight run. Where straight run limitations significantly reduce the available pipe diameters, FCI uses flow conditioners
to produce a transferable flow profile from the calibration installation to actual field installations. FCI's proprietary AVAL software is available
to make flow meter installation evaluations where straight run limitations are considered. See Figure C for recommended installation.

Process Connections The ST75 is available in pipe tee configurations with NPT threads and tubing tees with a compression fitting suitable to clamp down on concentric smooth surface tubing. The pipe tee versions are standard 150# class rated tees suitable for service up to 150 PSIG at the process temperature maximum of 250 °F (121 °C). -
Page 4: Instrument Wiring
Install an input power disconnect switch and fuse near the instrument to interrupt power during installation and maintenance. Operator must have power disconnected before wiring. See the “Specific Conditions of Use” and “Safety Instructions” sections in Appendix A for use of the ST75/ST75V (AC and DC versions) in Hazardous Areas Category II (Zone 1). -
Page 5: Pulse Output Activation
Pulse Output Activation The ST75/ST75V provides a pulse output feature. Instruments ordered with volumetric or mass flow units are factory set with totalizer and pulse output activated. The mode can be changed in the field. Source and sink output wiring is shown in Figures D and E below. -

ST75/ST75V Mass Flow Meter Fluid Components International LLC Start-up and Commissioning 1. Verify all input power and output signal wiring is correct and ready for initial power start-up. 2. Apply power to the instrument. The instrument initializes in the Normal Operation Mode with all outputs active. An instrument with the display option indicates flow with the factory-set flow units. - Page 8 The user cannot exit some routines unless all entries are completed or the power is cycled. The top level of the menu is shown in “Table 5. ST75/ST75V List of Single Letter Commands” on page 23. Enter the command letter mnemonic as listed in the tables below and in Appendix B to run a command.

Equipment Needed Flow Instrument Calibration Data... - Page 12 The instrument uses a set of predetermined calibration parameters to process flow signals. Most of these parameters should not change. A data package shipped with the instrument (typically on a CD-ROM) contains the ST75/ST75V Delta R Data Sheet. This contains the calibration parameters stored in the flow transmitter at the factory. To verify that these parameters have not changed, complete the following: Identify the appropriate Delta R data sheets by serial number of the instrument.

Contact FCI to obtain a Return Authorization before returning the instrument. The form contains a declaration of decontamination cleaning information that the instrument must comply with before it is shipped to FCI.

Connect the resistance decade box to the electronics as per the appropriate wiring diagram for the ST75/ST75V. Note: Interconnecting wiring (resistance decade box to electronics) must be same gauge and length to avoid any inaccura- cies in the Delta R verification caused by unequal wire lengths and/or wire gauges.
