ST51 MASS FLOW METER
Installation and Operation Guide
Pre-Installation
The ST51 can be specified with integral or remote electronics. The flow element has a serial number etched into the side of the
extension pipe as shown in Figure A. The 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 flat. These flow elements have
been calibrated in a particular direction and are designed to be used in service with the flow arrow facing in the same direction as
flow in the pipe stream. See Appendix C for orientation and factory calibration details.

Recommended Straight Run
To optimize flow meter system performance, FCI recommends installation with a minimum of 20 pipe diameters upstream straight
run and 10 pipe diameters of downstream straight run. Where straight run limitations significantly reduce the available pipe diam-
eters, FCI uses Vortab flow conditioners to produce a transferable flow profile from the calibration installation to actual field installa-
tions. 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.
Figure C
FCI flow meters may be installed with less than the recommended straight run, but may have performance limitations. FCI offers
Vortab flow conditioners for use in applications that have significant straight run limitations. FCI uses the AVAL application model-
ing software to predict meter performance in each installation. AVAL outputs are available to review prior to order placement and
will indicate performance expectations both with and without Vortab flow conditioning.

Summary of Contents for FCI ST51-1

  • Page 1 10 pipe diameters of downstream straight run. Where straight run limitations significantly reduce the available pipe diam- eters, FCI uses Vortab flow conditioners to produce a transferable flow profile from the calibration installation to actual field installa- tions. FCI’s proprietary AVAL software is available to make flow meter installation evaluations where straight run limitations are considered.

    Fluid Components International LLC ST51 Mass Flow Meter Specifications Instrument Flow Transmitter Media Compatibility: Biogas, Digester Gas, Methane, Natural Enclosure: NEMA 4X [IP67], aluminum, dual conduit Gas, Air, Compressed Air, Nitrogen ports with either 1/2" Female NPT or M20x1.5 entries. Epoxy coated.
  • Page 3 Figure D. Couplings and threadolets come in various dimensions. Proper installation requires that the element be measured with consideration to process connection dimensions and pipe centerline. FCI recommends that the element be first installed in the line with the compression fitting lightly tightened around the extension, then slowly move the pipe extension forward until the element is at centerline as shown.
  • Page 4 A retractable packing gland, with ½" MNPT or ¾" MNPT threads and graphite or Teflon packing, is a process connection option. FCI single point flow meters are calibrated at the centerline of the process pipe. The flow element is properly mounted when the tip of the flow element is located .50 inches (13 mm) past the pipe centerline.
  • Page 5 ST51 Mass Flow Meter Fluid Components International LLC 5. Tighten the packing nut until the internal packing is tight enough to prevent excess process leakage, but also allow the insertion probe to be inserted into place. For ball valve applications, open the ball valve after the packing nut has been tightened.

  • Page 6: Instrument Wiring

    Make sure power is OFF before wiring the instrument. Pull the power and signal output wires through the port, using care not to damage wires. FCI recommends using crimp lugs on the output wires to ensure proper connection with the terminal strip. Connect the output wires as shown on Figures G and H.
  • Page 7 ST51 Mass Flow Meter Fluid Components International LLC Pulse Output Activation The ST51 provides a pulse output feature. Instruments ordered with volumetric or mass flow units will be 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 G and H below. Though only one configuration is shown with the VAC and VDC power supplies, the source or sink can be used with either power input.
  • Page 8 If a computer interface is used, an adapter (RJ to 9-pin PC serial port) is required. The adapter can be obtained from FCI: Part No. 014108-02. Using a serial comm/terminal program (e.g., HyperTerminal, TeraTerm, Putty, etc.) configure the PC’s serial port (the one intended to be connected to the instrument) as listed below.
  • Page 9 ST51 Mass Flow Meter Fluid Components International LLC Startup and Commissioning 1. Verify all input power and output signal wiring is correct and ready for initial power startup. 2. Apply power to instrument. The instrument initializes in the Normal Operation Mode with all outputs active. An instrument with the display option will show flow with the factory-set flow units.
  • Page 10 1 SCFM, and the new span (20 mA) must be equal to or less than 100 SCFM. Some entries require a Factory pass code. If this occurs contact FCI Field Service to continue programming the instrument. The instrument will prompt the user when this is necessary.
  • Page 11 ST51 Mass Flow Meter Fluid Components International LLC “V” Menu Output Configuration Setup Use the V menu to set up the 4-20 mA analog outputs (including NAMUR configuration) and source/sink (pulse) outputs. Note: The display comes up to the last setting saved and stays for 2 seconds. If N or [ENTER] is entered, the menu proceeds to the Pulse out.
  • Page 12 If no change, select N and/or [ENTER] to continue to normal operation (programming finished). Maintenance The FCI instrument requires little maintenance. There are no moving parts or mechanical parts subject to wear in the instrument. The sensor assembly, which is exposed to the process media, is composed of 316 SS and Hastelloy C.

Equipment Needed Flow Instrument Calibration Data Process Parameters and Limits Check Serial Numbers Verify that the serial number of the flow element and the flow transmitter electronics are the same.
  • Page 14 Fluid Components International LLC ST51 Mass Flow Meter Calibration Parameters Verification The instrument uses a set of predetermined calibration parameters to process flow signals. Most of these parameters should not change. A data package included with this manual contains the ST51 Delta R data sheet. This contains the calibration parameters stored in the flow transmitter at the factory.
  • Page 15 Check the fuse for continuity. If fuse reads open, replace with equivalent component (FCI part no. 019933-01), Wickmann Inc. Series 374, 1.6 A (amp code 1160), package 0410 (short radial leads).
