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 on 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 diameters, FCI
utilizes Vortab 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 Fig 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.

Epoxy coated.
  • Page 3 The ST51 is available with both Teflon compression fitting ferrules and metal ferrules. While the Teflon ferrule configuration can be readjusted, it is possible that over tightening may result in permanent positioning or damage to the extension pipe and will make future adjustment difficult.

  • Page 4: Instrument Wiring

    Input Power The ST51 is available with both VDC and VAC input power configurations. Customers selecting VDC input power will have a VDC input board only. Similarly, the VAC power board is supplied only with VAC powered units. In addition, both boards are marked for either AC or DC power.
  • Page 5 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. Wiring either sink or source mode is shown in Figures E and F below.

  • Page 6: Setup Interface

    If a computer interface is used, an adapter (RJ to 9 pin Computer Serial Port) is required and may be obtained from FCI: Part No. 014108-02. Using Windows Terminal (usually located in Accessories) execute the program by double-clicking on the Terminal Icon.

    ST51 MASS FLOW 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 instrument. The instrument will initialize in the Normal Operation Mode. All outputs will be active and instru- ments with the display option will indicate flow with the factory set flow unit.
  • Page 8 SCFM, the new span (20mA) 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. Do not change any parameters that require this code unless there is an absolute understanding of the instrument's operation.

  • Page 10 PDA IR Communication Interface The IR interface software is an optional accessory kit and can ordered using FCI part number 019819-01. The software is compatible with PALM OS 4.1 or greater. If the software was ordered with the instrument, a CD should be located with the instrument documen- tation.

  • Page 11: Maintenance

    FLUID COMPONENTS INTERNATIONAL LLC 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 13 The instrument uses a set of predetermined calibration parameters to process flow signals. Most of these parameters should not change. A data package located with this manual contains the “ST51 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: 1.

    3. Mark all sensor element wires connected to the circuit board, so they may be reconnected to the proper terminals. Disconnect the wires. 4. Connect the resistance decade box to the electronics as per the appropriate diagram for the ST51. NOTE: Interconnector wiring (resistance decade box to electronics) must be 24 AWG and 45 inches long, to avoid any inaccuracies in the Delta R verification, caused by improper wire lengths or wire gauges.
