22 MI June Installation Piping Considerations and Mounting Position Refer to the pocket-size bulletin, Ensuring Premium Performance with Foxboro 83 Series Intelligent Vortex Flowmeters shipped with your flowmeter. This provides recommended flowmeter mounting position relative to the type of fluid. Mechanical Installation Procedures 83F Flanged Body Mounting the Flowmeter Body 1. Gaskets are required and must be supplied by the user. Select a gasket material suitable for the process. 2. Insert gaskets between the body of the flowmeter and adjacent flanges. See Figure 6. Position the gaskets so that the ID of each gasket is centered on the ID of the flowmeter and adjacent piping.! CAUTION Verify that the ID of the gaskets is larger than that of the flowmeter bore and pipe and that the gaskets do not protrude into the meter entrance or exit. Protrusion into the flowstream has an adverse effect on performance.! CAUTION Gaskets do not prevent flanges from being wetted by process fluids. NOTE When you install new flanges in the process piping and use the meter as a gauge to set the flanges, protect the inside diameter of the flowmeter from weld splatter. Install a solid sheet of gasketing at each end of the meter during welding. Remove this sheet and install the flange gaskets after welding. Remove any splatter in either the pipe or the meter as it could affect flowmeter accuracy. GASKET GASKET ARROW FLOWMETER NOTE: install the flowtube so that the arrow on the tube points in the same direction as the direction of flow. DIRECTION OF FLOW Figure 6. 83F Flowmeter Body Installation 3. Visually inspect for concentricity (centering and alignment) of mating flanges. 12

23 2. Installation MI June Tighten bolts in accordance with conventional flange bolt tightening practice (that is, incremental and alternate tightening of bolts). Mounting a Remote Electronics Housing If you specified a remote electronics housing on your order, your flowmeter body and electronics housing are connected by a signal cable. Mount the housing to a wall or to a DN50 or 2-inch pipe using the mounting bracket assembly provided. If the flowmeter and electronics housing must be separated for installation with conduit or for any other reason, it is recommended that you disconnect the cable at the electronics housing end. If the cable must be shortened, shorten the electronic housing end per the procedure in MI (83 -A), MI (83 -F), MI (83 -D), or MI (83 -T), on your CD-ROM. To install the flowmeter using conduit, use the following procedure: 1. Remove the electronic module compartment cover from the electronics housing. 2. Unscrew the two captive screws, one on each side of the electronic module. 3. Pull out electronic module far enough to disconnect the remote signal cable. 4. Disconnect the four remote signal wires from the four position terminal block on the rear of the electronic module. 5. Unscrew the knurled nut and pull it back onto the cable jacket. Also pull the rubber bushing onto the cable jacket. Leave these parts on the cable jacket as they will be used when reconnecting the cable. See Table Run the remote cable to the electronic module housing via the conduit. 7. Taking care not to damage the copper braid, push the cable into the connector at bottom of the electronic housing until the outer jacket bottoms out inside the connector. 8. Push the rubber bushing into position, until it sits snug inside the connector. 9. Tighten the knurled nut on the connector to create a compression fit for a good seal. 10. Mount the conduit box or conduit to the 1/2 NPT connector directly or via a 3-piece union/coupler, if necessary. 11. Inside the electronic housing, connect the four signal wires to the color coded 4- position terminal block on the rear of the electronic module. 12. Ensure that the signal and loop power wires are tucked under the electronic module. Taking care not to pinch the wires, place the module in the housing. Tighten the two captive mounting screws. 13. Replace the threaded housing cover tightly. This will prevent moisture or other contaminants from entering the compartment. 13

25 2. Installation MI June W Wafer Body Mounting the Flowmeter Body For optimal performance, the wafer body flowmeter should be centered with respect to the adjoining pipe. Normally, this requires the use of centering fixtures that are supplied with the meter. NOTE Centering fixtures are not required for meters with ANSI Class 150 flanges. There are two sets of centering fixtures, one for each side. 1. See Figure 7. Insert the first stud through the downstream flange at one of the lower holes, through two hex-nut spacers, and then through the upstream flange. Place the nuts on both ends of the stud, but do not tighten. 2. Using the remaining hex-nut spacers, repeat Step 1 at the lower hole adjacent to the first. 3. Set the flowmeter between the flanges. For centering with the hex-nut spacers, rotate spacers to the thickness that centers the meter. NOTE By rotating the hex-nut spacers to the correct thickness, you can center the meter to any type of flange. 4. Gaskets are required and must be supplied by the user. Select a gasket material suitable for the process fluid. 5. Insert gaskets between the body of the flowmeter and adjacent flanges. Position the gaskets so that the ID of each gasket is centered on the ID of the flowmeter and adjacent piping.! CAUTION Verify that the ID of the gaskets is larger than that of the flowmeter bore and pipe and that the gaskets do not protrude into the meter entrance or exit. Protrusion into the flowstream has an adverse effect on performance. NOTE If welding the flanges to the process piping is required, protect the flowmeter from weld splatter, which could affect flowmeter accuracy. A solid sheet of gasketing should be installed at each end of the meter during welding. Remove this sheet and install the flange gaskets after welding. 6. Visually inspect for concentricity (centering and alignment) of mating flanges. 7. Install the rest of the studs and nuts and tighten the nuts in accordance with conventional flange bolt tightening practice (that is, incremental and alternate tightening of bolts). If flanges cannot be properly aligned, align the meter with the upstream flange rather than the downstream flange. 15

26 MI June Installation GASKET FLOWMETER GASKET 2 HEX-NUT SPACERS PER SIDE (NOT REQUIRED WITH CLASS 150) INSTALL CENTERING FIXTURES ON ADJACENT LOWER STUDS OF FLANGE NOTE: install the flowtube so that the arrow on the tube points in the same direction as the direction of flow. HEX-NUT ALIGNMENT DEVICE (NOT REQUIRED WITH CLASS 150) Figure 7. 83W Flowmeter Centering Mounting a Remote Electronics Housing Refer to Mounting a Remote Electronics Housing on page S Sanitary Flowmeter Mounting the Flowmeter Body Firmly secure the cable that connects the flowmeter body to the electronic housing. The support should be approximately 30 cm (12 in) from the flowmeter body. A loose cable may cause wear at the cable connection and can result in signal noise. The temperature limit of the cable is 105 C (220 F). Do not support the cable on a surface exceeding this temperature. See Figure 8. APPROXIMATELY 30 CM (12 IN) Figure 8. 83S Flowmeter Body Cable Support 16

27 2. Installation MI June 2010 The flowmeter body has six different end connection possibilities. The end connections on your flowmeter body were specified as part of your order. All end connections are welded to the flowmeter body. The mating end connections, gaskets, and clamps are supplied by you, the user.! WARNING The maximum pressure limit of the flowmeter is 1.9 MPa (275 psig) or the limit of the end connection used, whichever is less. For interpretation of model code references, refer to PL on your CD-ROM. Dimensional information on the end connections can be found in DP on your CD-ROM. Mounting the Electronics Housing The electronic housing can be either pipe or wall mounted. Do not mount the electronic housing on process piping. Excess vibration may damage the amplifier and amplifier housing. Support the cable that connects the flowmeter body to the electronic housing. The support should be approximately 30 cm (12 in) from the electronic housing. A loose cable may cause wear at the cable connections (see Figure 9). The temperature limit of the cable is 105 C (220 F). Do not support the cable on any surface that exceeds this temperature.

28 MI June Installation Field Termination Wiring NOTE The wiring installation must conform to local and national regulations applicable to the specific site and classification of the area. The housing comes with a safety-agency approved threaded metal plug in one of the conduit holes and a plastic plug in the other. After the conduit or cable gland is connected, plug the unused hole with the metal plug using thread sealant. Remove the field terminal compartment cover (shown in Figure 10) to make field wiring connections. Keep the electronic module compartment cover closed to prevent moisture and atmospheric contaminants from entering the compartment. When replacing the cover, tighten the cover to compress the O-ring seal. FIELD TERMINAL COMPARTMENT ELECTRONIC MODULE COMPARTMENT ELECTRICAL CONDUIT OPENING Figure 10. Electronics Housing There are three basic wiring combinations, the choice of which depends on how your flowmeter is to be used: 2-Wire Hook-Up for standard output 3-Wire Hook-Up for scaled pulse only 4-Wire Hook-Up for standard output plus scaled pulse communication. 2-Wire Hook-Up Connect the supply and receiver loop wiring (0.50 mm 2 or 20 AWG typical) to the terminals in the field-terminal compartment of the transmitter, as shown in Figure

Installation MI June 2010 CASE GROUND TERMINAL (EARTH) TERMINAL BLOCK POWER SUPPLY RECEIVER OHM MIN LOAD REQUIRED FOR INTELLIGENT COMMUNICATION A B TWO 1/2 NPT CONDUIT CONNECTIONS ARE PROVIDED (ON OPPOSITE SIDES). INSERT PLUG IN CONNECTION NOT USED. Figure 11. Installation Wiring (2-Wire Hook-Up) Model 83 -D (with Analog Output) or Model 83 -T Twisted pair wiring should be used to prevent electrical noise from interfering with the dc current output signal. In some instances, shielded cable may be necessary. Earthing (grounding) of the shield should be installed at one point only (at the power supply). Do not ground the shield at the transmitter. Transmitter connection polarities are indicated on the terminal block. If the loop is to contain additional instruments, install them between the negative terminal of the transmitter and the positive terminal of the receiver, as shown in Figure 11. The required loop power supply voltage is based on the total loop resistance. To determine the total loop resistance, add the series resistance of each component in the loop (do not include transmitter). The required power supply voltage can be determined from Figure ADDITIONAL RECEIVERS IN LOOP HART COMMUNICATOR PC- BASED CONFIGURATOR, OR I/A SERIES SYSTEM 19

Load Requirements - Model 83 -D or Model 83 -T The transmitter will function with an output load less than 250 ohms, provided that a configurator is not connected to it. Connecting a configurator to a loop with less than 250 ohms may cause communication problems. As an example, for a transmitter with a loop resistance of 500 ohms, referring to Figure 12, the minimum power supply voltage is 22 V dc, while the maximum power supply voltage is 42 V dc. Conversely, given a power supply voltage of 24 V dc, the allowable loop resistance is from 250 to 565 ohms. NOTE 1. The power supply must be capable of supplying 22 ma. 2. Power supply ripple must not allow the instantaneous voltage to drop below 12.5 V dc at the transmitter. 3. The recommended minimum load is 250 ohms. 4. For wiring to an I/A Series system, refer to MI on your CD-ROM. Model 83 -A Twisted pair wiring should be used to prevent electrical noise from interfering with the dc current output signal. In some instances, shielded cable may be necessary. Earthing (grounding) of the shield should be at one point only at the power supply. Do not earth (ground) the shield at the transmitter. 20

31 2. Installation MI June 2010 Transmitter connection polarities are indicated on the terminal block. If the loop is to contain additional instruments, install them between the negative terminal of the transmitter and the positive terminal of the receiver, as shown in Figure 11. The required loop power supply voltage is based on the total loop resistance. To determine the total loop resistance, add the series resistance of each component in the loop (do not include transmitter). The required power supply voltage can be determined by referring to Figure 12. Figure 13. Load Requirements - Model 83 -A As an example, for a transmitter with a loop resistance of 600 ohms, referring to Figure 12, the minimum power supply voltage is 24 V dc, while the maximum power supply voltage is 50 V dc. Conversely, given a power supply voltage of 24 V dc, the allowable loop resistance is from 0 to 600 ohms. NOTE 1. The power supply must be capable of supplying 22 ma. 2. Power supply ripple must not allow the instantaneous voltage to drop below 10.5 V dc. Model 83 -F A flowmeter with FOUNDATION fieldbus communications protocol connects to the bus. Power for the flowmeter is supplied by a FOUNDATION fieldbus power supply module which may be connected anywhere on the bus. Therefore, the power supply and receiver connections shown in Figure 11 are not applicable. Also, there are no polarity requirements with FOUNDATION fieldbus devices. 21

32 MI June Installation 3-Wire Hook-Up NOTE 4-Wire Hook-Up is preferred. For 3-Wire Hook-Up, refer to MI (83 - D), or MI (83 -T), on your CD-ROM. 4-Wire Hook-Up A separate loop is required when a pulse output is also required. This loop requires its own power supply. Refer to Figure 14. Select the resistor so that the current through the contact closure does not exceed 250 ma.

Electronic Module Switch Locations Signal Noise Filter Switches Electronic filtering is provided in the electronic module to reduce the effect of noise and vibration on the vortex signal. The electronic module noise filter is set at the factory based on the customerspecified flow range. The electronic module filter consists of both high and low frequency noise 23

34 MI June Quick Start filters. Each filter can be independently set, allowing the filtering to be tailored to each application. The filters are settable by the switches on the front of the electronic module. For most installations, there should be no need to change the filter. Approximate Filter Settings If the filters have not been factory set, or if no information is available on either the frequency at maximum flow or the frequency at low flow cut-in, the following settings are recommended as initial settings. Line Size Table 6. Approximate Filter Settings Setting the Electronic Module Filters Set Steps per Table 7 Set Steps per Table 8 Liquid A,B,C Gas A,B,C Liquid D,E,F NOTE The approximate filter settings shown in Table 6 are satisfactory for many installations. Gas D,E,F 3/4, /2, The high frequency noise filter switches are labeled A, B, and C, on the electronic module label board. They are set based on the upper range frequency (calibration frequency) using Table 7. Choose a filter setting for which the upper range frequency falls within the correct step listed in the table. This frequency is shown on the label on the front of the electronic module. The upper range frequency must be known even when the meter is to be used in the pulse output mode. The low frequency filter switches are labeled D, E, and F and are set according to the low flow cut-in frequency. This may be determined from the rangeability factor shown on the sizing program. Simply divide the upper range frequency by the rangeability. Then refer to Table 8 to set the switch positions. 24

Occasionally, erratic output conditions can occur at low flows. This is due to system noise such as pulsing pumps, surging flows, or vibrating pipes. To eliminate these false signals, the low flow cut-in can be raised. Raising the low flow cut-in by one step will increase the low flow cut-in by a factor of two. All flowmeters are set at the factory to the LOW low flow cut-in position, which is the default setting. This setting can be increased to achieve greater noise immunity as described above. It may be decreased for lower flow rate measurement capability as shown in Table 9. Low Flow Cut-In Table 9.

Output Mode Selection Switch J Position Off On Output Mode 4 to 20 ma dc Pulse Calibration Switches Your flowmeter has been factory calibrated to the specified Upper Range Value (URV). If the correct flow range was specified with the purchase order, and the 4 to 20 ma output mode switch (J) and the signal noise filter switches (A-F) have been set correctly, no further calibration is required. If you are using a different flow range or further calibration is required for some other reason, refer to MI on your CD-ROM. NOTE Setting switch J to the pulse output mode disables the calibration switches. Calibration for URV is unnecessary in the pulse output mode. NOTE Certain installations and flow conditions affect flowmeter performance. These effects can alter the calibrated K-factor in either the 4 to 20 ma or pulse mode. To correct for these effects, refer to MI on your CD-ROM. Models 83 -D, 83 -T, 83 -F Each flowmeter is shipped from the factory with an operating configuration database. However, the flowmeter will not provide an accurate measurement if the configuration does not fit your application. Be sure to check the configuration of your flowmeter prior to start-up. If the user information is not supplied with the purchase order, the flowmeter is shipped with the following defaults: Table 11.
