Installation and Operation Guide

Pre-Installation

Serial Number Alignment

The ST75 and ST75V (Vortab) can be specied with integral or remote electronics. The ow 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 ow 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 ow arrow indicator marked on the element assembly at the reference HEX at. These ow elements have been calibrated in a particular direction and are designed to be used in service with the ow arrow going in the same direction as ow in the pipe stream. The ow 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 ow 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 signicantly reduce the available pipe diameters, FCI uses ow conditioners to produce a transferable ow prole from the calibration installation to actual eld installations. FCI’s proprietary AVAL software is available to make ow meter installation evaluations where straight run limitations are considered. See Figure C for recommended installation.

FCI ow meters may be installed with less than the recommended straight run, but at the risk of limiting performance. FCI offers VORTAB ow conditioners for use in applications that have signicant straight run limitations. FCI uses the AVAL application modeling 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 ow conditioning.

Flow Element Installation

Caution: The element is shipped installed in the tee, with the element specically oriented for inline installation. Do not remove the sensing element from the tee section during installation as calibration can be adversely affected.

Process Connections

The ST75 is available in pipe tee congurations with NPT threads and tubing tees with a compression tting 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). The compression tting material offered in the tube type conguration is rated for 250 PSIG service.

Pipe Tee Installation: With pipe extensions properly cut to length and the appropriate sealing materials used on the threads, install ow element section by slowly rotating the conguration until rmly secure on the pipe section. Complete by installing opposing end pipe section using care to rmly secure the element assembly either in a top mount or side mount position.

Tube Tee Installation: Clean all mating surfaces of the tee tting, ferrules and the ow tube. Insert the ow tubing into the tee tting. Make sure the tubing rests rmly in the tting counter bore seat. Tighten the nut on both ends of the tee by hand. Hold the tting body steady with a backup wrench, tighten the tting nuts 1-1/4 turns, from hand tight baseline.

The ST75V is available in with ow tube congurations offering male and female NPT threads, ANSI anges and DIN anges. The ow tube assemblies are rated for service up to 240 PSIG at the process temperature maximum of 250 °F (121 °C).

NPT Flow Tube Installation: With pipe extensions properly cut to length and the appropriate sealing materials used on the threads, install ow element section by slowly rotating the conguration until rmly secure on the pipe section. Complete by installing opposing end pipe section using care to rmly secure the element assembly either in a top mount or side mount position.

Instrument Wiring

Before opening the instrument to connect power and signal observe the following ESD precautions:

Use a wrist band or heel strap with a 1 megohm resistor connected to ground. If the instrument is in the shop setting, use a static conductive mat on the work table or oor with a 1 megohm resistor connected to ground. Connect the instrument to ground. Apply antistatic agents such as Static Free made by Chemtronics (or equivalent) to hand tools to be 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. Dept. of Defense Handbook 263.

Warning: Only qualied personnel are to wire or test this instrument. The operator assumes all responsibility for safe practices while wiring and troubleshooting.

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 “Specic 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).

Input Power

The ST75/ST75V is available with both VDC and VAC input power congurations. 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. Only connect the power specied on the wiring module as shown on Figures D and E respectively. Both VAC and VDC inputs require a Gnd wire to be connected. Input power terminal blocks accept 14-26 AWG wire.

Make sure that 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 D and E. Note that when the 4-20 mA outputs are used simultaneously, a single return lead is used.

Analog Output

4-20 mA: The instrument is provided with two 4-20 mA outputs. By default Output 1 is congured for ow and Output 2 is congured for

temperature. Terminal blocks accept 14-28 AWG wire, 500 ohms max load per output.

Setup Interface

All parameters on this meter are set through the RS232 interface connection (P3 plug). The RS232 interface allows the instrument to be set up with either an FC88 hand held communicator or a computer. The FC88 is powered through the meter and comes with the serial interface cable. 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.) congure the PC’s serial port (the one intended to be connected to the instrument) as listed in the table below.

RS232 / FC88

Menu Control and Organization

Most entries require at least two keystrokes; a capital letter and the [ENTER] key, or one or more numbers and the [ENTER] key. All user entries begin at the input mode prompt “>”, except when the instrument is in the Main Function Mode (just press the desired function letter and [ENTER] to make an entry).

Backspaces are made using the backspace [BKSP] key. Some entries are case sensitive between numbers and letters. Be sure the SHIFT key is pressed to indicate the correct case. A square after the prompt caret indicates the FC88 is in lower case. A slightly raised rectangle in the same spot indicates the FC88 is in the upper case.

It is recommended that the FC88 be plugged into the instrument before power is applied. If the FC88 is plugged in while the instrument power is on and the FC88 does not respond, press [ENTER]. If there is still no response press [N] or cycle the power.

Note: The Zero and Span may be changed from the original calibration, provided the new values are within the original calibrat ed range; i.e., if the original calibration was 1 to 100 SCFM (4-20 mA), the new zero (4 mA) must be equal to or greater than 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. Do not change any parameters that require this code unless there is an absolute understanding of the instrument’s operation. 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. Exit a command at any time by entering “Q” [ENTER] in the

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.

Without detailed knowledge of the environmental parameters of the application surroundings and process media, FCI cannot make specic recommendations for periodic inspection, cleaning, or testing procedures. However, some suggested general guidelines for maintenance steps are offered below. Use operating experience to establish the frequency of each type of maintenance.

Calibration

Periodically verify the calibration of the output and recalibrate if necessary. FCI recommends every 18 months at a minimum.

Note: Thirty (30) second warm-up required before calibration check.

Periodically inspect cable connections on terminal strips and terminal blocks. Verify that terminal connections are tight and physically sound with no sign of corrosion.

Remote Enclosure

Verify that the moisture barriers and seals protecting the electronics in the local enclosure is adequate and that no moisture is entering the enclosure.

Electrical Wiring

FCI recommends occasional inspection of the system’s interconnecting cable, power wiring and ow element wiring on a “common sense” basis related to the application environment. Periodically inspect the conductors for corrosion and check the cable insulation for signs of deterioration.

Flow Element Connections

Verify that all seals are performing properly and that there is no leakage of the process media. Check for deterioration of the gaskets and environmental seals used.

Troubleshooting

Application Verication

After verifying that the ow meter is functioning, review the application parameters as shown below to verify the calibration matches the process media.

Equipment Needed

Flow Instrument Calibration Data Process Parameters and Limits

Check Serial Numbers

Verify that the serial number of the ow element and the ow transmitter electronics are the same. The ow element and the ow transmitter are a matched set and cannot be operated independently of each other.

Check the Instrument Installation

Verify correct mechanical and electrical installation. Verify the ow element is mounted at least 20 diameters downstream and 10 diameters upstream from any bends or interference in the process pipe or duct.

Check for Moisture

Check for moisture on the ow transmitter. Moisture may cause intermittent operation. Check for moisture on the ow element. If a compo nent of the process media is near its saturation temperature it may condense on the ow element. Place the ow element where the process media is well above the saturation temperature of any of the process gases.

Check Application Design Requirements

Application design problems may occur with rst time application instruments, although the design should also be checked on instruments that have been in operation for some time. If the application design does not match eld conditions, errors occur.

1. Review the application design with plant operation personnel and plant engineers.

2. Ensure that plant equipment such as pressure and temperature instruments conform to the actual conditions.

3. Verify operating temperature, operating pressure, line size, and gas medium.

Verify Standard Versus Actual Process Conditions

The ow meter measures the mass ow rate. The mass ow rate is the mass of the gas owing through a pipe per time. Other ow meters, such as an orice plate or a pitot tube, measure the volumetric ow rate. The volumetric ow rate is the volume of gas per time. If the readings displayed do not agree with another instrument, some calculations may be necessary before comparing them. To calculate the mass ow rate, the volumetric ow rate, and the pressure and temperature, the point of measurement must be known. Use the following equation to calculate the mass ow rate (Standard Volumetric Flow rate) for the other instrument:

Equation:

Q Q

= × ×

S A

Where: QA= Volumetric Flow QS= Standard Volumetric Flow

PA= Actual Pressure TA= Actual Temperature PS= Standard Pressure TS= Standard Temperature PSIA and °R are used for pressure and temperature units.
