It does not provide instructions for detailed configuration, diagnostics, maintenance, service, troubleshooting, explosion-proof, flame-proof, or intrinsically safe (I.S.) installations. Refer to the Rosemount 8712 reference manual (document number 00809-0100-4664) for more instructions. The manual and this QIG are also available electronically on www.rosemount.com. WARNING Failure to follow these installation guidelines could result in death or serious injury: Installation and servicing instructions are for use by qualified personnel only. Do not perform any servicing other than that contained in the operating instructions, unless qualified. Verify that the operating environment of the sensor and transmitter is consistent with the appropriate FM, CSA, ATEX, or IECEx approval. Do not connect a Rosemount 8712 to a non-Rosemount sensor that is located in an explosive atmosphere. WARNING The sensor liner is vulnerable to handling damage. Never place anything through the sensor for the purpose of lifting or gaining leverage. Liner damage can render the sensor useless. To avoid possible damage to the sensor liner ends, do not use metallic or spiral-wound gaskets. If frequent removal is anticipated, take precautions to protect the liner ends. Short spool pieces attached to the sensor ends are often used for protection. Correct flange bolt tightening is crucial for proper sensor operation and life. All bolts must be tightened in the proper sequence to the specified torque limits. Failure to observe these instructions could result in severe damage to the sensor lining and possible sensor replacement. 2 4664RevBBQIG.fm Page 3 Friday, January 11, 2013 6:13 PM Quick Installation Guide 00825-0100-4664, Rev BB January 2013 Rosemount 8712 / 8700 Series STEP 1: PRE-INSTALLATION Before installing the Rosemount 8712 Magnetic Flowmeter Transmitter, there are several pre-installation steps that should be completed to make the installation process easier: • Identify the options and configurations that apply to your application • Set the hardware switches if necessary • Consider mechanical, electrical, and environmental requirements Mechanical Considerations The mounting site for the Rosemount 8712 transmitter should provide enough room for secure mounting, easy access to conduit ports, full opening of the transmitter covers, and easy readability of the LOI screen (see Figure 1). The Rosemount 8712 is mounted separately from the sensor, it is not subject to limitations that might apply to the sensor. 3 4664RevBBQIG.fm Page 4 Friday, January 11, 2013 6:13 PM Quick Installation Guide 00825-0100-4664, Rev BB January 2013 Rosemount 8712 / 8700 Series Figure 1.

Typical problem areas include: • Warm-climate installations in direct sunlight • Outdoor installations in cold climates Remote mounted transmitters may be installed in the control room to protect the electronics from the harsh environment and provide easy access for configuration or service. Remotely mounted Rosemount 8712 transmitters require external power so there must be access to a suitable power source. Installation Procedures Rosemount 8712 installation includes both detailed mechanical and electrical installation procedures. Mount the Transmitter At a remote site the transmitter may be mounted on a pipe up to two inches in diameter or against a flat surface. Pipe Mounting To mount the transmitter on a pipe: 1. Attach the mounting plate to the pipe using the mounting hardware. 2. Attach the 8712 to the mounting plate using the mounting screws. Identify Options and Configurations The standard application of the 8712 includes a 4–20 mA output and control of the sensor coils and electrodes. Other applications may require one or more of the following configurations or options: • Multidrop Communications • Digital Output • Digital Input • Pulse Output Additional options may apply. Be sure to identify those options and configurations that apply to your situation, and keep a list of them nearby for consideration during the installation and configuration procedures. Hardware Jumpers/Switches The 8712 electronics board is equipped with three user-selectable hardware switches. These switches set the Failure Alarm Mode, Internal/External Analog Power, and Transmitter Security. The standard configuration for these switches when shipped from the factory are as follows: Failure Alarm Mode: HIGH Internal/External Analog Power: INTERNAL Transmitter Security: OFF Changing Hardware Switch Settings In most cases, it is not necessary to change the setting of the hardware switches. If you need to change the switch settings, complete the steps outlined in the manual. 5 4664RevBBQIG.fm Page 6 Friday, January 11, 2013 6:13 PM Quick Installation Guide Rosemount 8712 / 8700 Series 00825-0100-4664, Rev BB January 2013 Electrical Considerations Before making any electrical connections to the Rosemount 8712, consider local and plant electrical standards and be sure to have the proper power supply, conduit, and other accessories necessary to comply with these standards. STEP 2: HANDLING Handle all parts carefully to prevent damage. Whenever possible, transport the system to the installation site in the original shipping containers. PTFE-lined sensors are shipped with end covers that protect it from both mechanical damage and normal unrestrained distortion. Remove the end covers just before installation. Figure 2. Rosemount 8705 Sensor Support for Handling ½- through 4-Inch Sensors 6 6-Inch and Larger Sensors 4664RevBBQIG.fm Page 7 Friday, January 11, 2013 6:13 PM Quick Installation Guide 00825-0100-4664, Rev BB January 2013 Rosemount 8712 / 8700 Series STEP 3: MOUNTING Upstream/Downstream Piping To ensure specification accuracy over widely varying process conditions, install the sensor a minimum of five straight pipe diameters upstream and two pipe diameters downstream from the electrode plane (see Figure 3). Figure 3. Upstream and Downstream Straight Pipe Diameters 5 Pipe Diameters 2 Pipe Diameters Flow Installations with reduced straight runs from 0 to 5 pipe diameters are possible. In reduced straight pipe run installations, performance will shift to as much as 0.5% of rate. Reported flow rates will still be highly repeatable. Flow Direction The sensor should be mounted so the FORWARD end of the flow arrow, shown on the sensor identification tag, points in the direction of flow through the sensor. Sensor Orientation The sensor should be installed in a position that ensures the sensor remains full during operation. Vertical installation allows upward process fluid flow and keeps the cross-sectional area full, regardless of flow rate. Horizontal installation should be restricted to low piping sections that are normally full. In these cases, orient the electrode plane to within 45° of horizontal. 7 4664RevBBQIG.fm Page 8 Friday, January 11, 2013 6:13 PM Quick Installation Guide 00825-0100-4664, Rev BB January 2013 Rosemount 8712 / 8700 Series Figure 4. Sensor Orientation FLOW FLOW The electrodes in the Rosemount 8705 sensor are properly orientated when the two measurement electrodes are in the 3 and 9 o’clock positions, as shown on the right of Figure 4. The electrodes in the Rosemount 8711 are properly orientated when the top of the sensor is either vertical or horizontal, as shown in Figure 5. Avoid any mounting orientation that positions the top of the sensor at 45° from the vertical or horizontal position. Figure 5.

The gasket material selected must be compatible with the process fluid and operating conditions. Metallic or spiral-wound gaskets can damage the liner. Gaskets are required on each side of a grounding ring. All other applications (including sensors with lining protectors or a grounding electrode) require only one gasket on each end connection. Figure 6. Flanged gasket placement Flange Bolts NOTE Do not bolt one side at a time. Tighten each side simultaneously. Example: 1. Snug left 2. Snug right 3. Tighten left 4. Tighten right Do not snug and tighten the upstream side and then snug and tighten the downstream side. Failure to alternate between the upstream and downstream flanges when tightening bolts may result in liner damage. Suggested torque values by sensor line size and liner type are listed in Table 1 for ASME B16.5 (ANSI) and Table 2 for DIN flanges. Consult the factory if the flange rating of the sensor is not listed. Tighten flange bolts on the upstream side of the sensor in the incremental sequence shown in Figure 7, to 20% of the suggested torque values. Repeat the process on the downstream side of the sensor. For sensors with more or less flange bolts, tighten the bolts in a similar crosswise sequence. Repeat this entire tightening sequence at 40%, 60%, 80%, and 100% of the suggested torque values or until the leak between the process and sensor flanges stop. 9 4664RevBBQIG.fm Page 10 Friday, January 11, 2013 6:13 PM Quick Installation Guide 00825-0100-4664, Rev BB January 2013 Rosemount 8712 / 8700 Series If leakage has not stopped at the suggested torque values, the bolts can be tightened in additional 10% increments until the joint stops leaking, or until the measured torque value reaches the maximum torque value of the bolts. Practical consideration for the integrity of the liner often leads the user to distinct torque values to stop leakage due to the unique combinations of flanges, bolts, gaskets, and sensor liner material. Check for leaks at the flanges after tightening the bolts. Failure to use the correct tightening methods can result in severe damage. Sensors require a second tightening 24 hours after the initial installation. Over time, sensor liner materials may deform under pressure. Figure 7.

The gasket material selected must be compatible with the process fluid and operating conditions. Metallic or spiral-wound gaskets can damage the liner. Gaskets are required on each side of a grounding ring. See Figure 8 below. Figure 8. Wafer gasket placement Spacer Installation Horizontal meters Vertical meters O-ring Alignment 1. On 1.5 through 8-inch (40 through 200 mm) line sizes. Rosemount strongly recommends installing the alignment spacers provided to insure proper centering of the wafer sensor between the process flanges. Sensor sizes of 0.15, 0.30, 0.5 and 1 in. (4 through 25 mm), do not require alignment spacers. 2. Insert studs for the bottom side of the sensor between the pipe flanges and center the alignment spacer in the middle of the stud. See Figure 8 for the bolt hole locations recommended for the spacers provided. Stud specifications are listed in Table 3. 3. Place the sensor between the flanges. Make sure that the alignment spacers are properly centered on the studs. For vertical flow installations slide the oring over the stud to keep the spacer in place. See Figure 8. To ensure the spacers match the flange size and class rating for the process flanges see Table 4. 4. Insert the remaining studs, washers, and nuts. 5. Tighten to the torque specifications shown in Table 5. Do not overtighten the bolts or the liner may be damaged. Table 3.

Follow the conduit information, cable requirements, and disconnect requirements in the sections below. Conduit Ports and Connections Both the sensor and transmitter junction boxes have ports for 1/2-inch NPT conduit connections with optional CM20 or PG 13.5 connections available. These connections should be made in accordance with national, local, and plant electrical codes. Unused ports should be sealed with metal plugs. Proper electrical installation is necessary to prevent errors due to electrical noise and interference. Separate conduits are not necessary for the coil drive and signal cables, but a dedicated conduit line between each transmitter and sensor is required. Shielded cable must be used for best results in electrically noisy environments. When preparing all wire connections, remove only the insulation required to fit the wire completely under the terminal connection. Removal of excessive insulation may result in an unwanted electrical short to the transmitter housing or other wire connections. For flanged sensors installed into an application requiring IP68 protection, sealed cable glands, conduit, and conduit plugs that meet IP68 ratings are required. Conduit Requirements A single dedicated conduit run for the coil drive and signal cable is needed between the sensor and the remote transmitter. See Figure 14. Bundled cables in a single conduit are likely to create interference and noise problems in the system. Use one set of cables per conduit run. Figure 14.

Run the power cable from the power source to the transmitter. Run the coil drive and signal cables between the flowmeter sensor and transmitter. • Installed signal wiring should not be run together and should not be in the same cable tray as AC or DC power wiring. • Device must be properly grounded or earthed according to local electric codes. • Rosemount combination cable part number 08732-0753-1003 (ft) or 08732-0753-2004 (m) is required to be used to meet EMC requirements. Transmitter to Sensor Wiring The transmitter can be integral to the sensor or remotely mounted following the wiring instructions. Remote Mount Cable Requirements and Preparation For installations using the individual coil drive and signal cable, lengths should be limited to less than 1,000 feet (300 meters). Equal length cable is required for each. See Table 7. For installations using the combination coil drive and signal cable, lengths should be limited to less than 330 feet (100 meters). See Table 7. Prepare the ends of the coil drive and signal cables as shown in Figure 15. Limit the unshielded wire length to 1-inch on both the coil drive and signal cables. Any unsheathed wire should be wrapped with proper insulation. Excessive lead length or failure to connect cable shields can create electrical noise resulting in unstable meter readings. Figure 15.

Connect the 4–20 mA Analog Signal Cabling considerations If possible, use individually shielded twisted pair cable, either in single pair or multi-pair varieties. Unshielded cables may be used for short distances, provided ambient noise and cross-talk will not adversely impact communication. The minimum conductor size is 0.51 mm diameter (#24 AWG) for cable runs less than 1,500 meters (@ 5,000 ft.) and 0.81 mm diameter (#20 AWG) for longer distances. Resistance in the loop must be 1000 ohms or less. The 4–20 mA analog output loop signal may be powered internally or externally. The default position of the internal/external analog power switch is in the internal position. The user-selectable power supply switch is located on the electronics board. 8712E - connect negative (-)DC to Terminal 8 and positive (+)DC to Terminal 7. See Figure 18. Figure 18. 8712E Analog Signal Wiring Diagram +4–20 mA –4–20 mA Internal Power Source The 4–20 mA analog signal loop is powered from the transmitter itself. External Power Source The 4–20 mA analog signal loop is powered from an external power source. HART multidrop installations require a 10–30 V DC external analog power source. NOTE: If a HART Field Communicator or control system will be used, it must be connected across a minimum of 250 ohms resistance in the loop. To connect any of the other output options (pulse output and/or digital input/output), consult the comprehensive product manual. 22 4664RevBBQIG.fm Page 23 Friday, January 11, 2013 6:13 PM Quick Installation Guide 00825-0100-4664, Rev BB January 2013 Rosemount 8712 / 8700 Series Powering the Transmitter The 8712E transmitter is designed to be powered by 90-250 Vac, 50–60 Hz or 12–42 Vdc. Before connecting power to the Rosemount 8712E consider the following standards and be sure to have the proper power supply, conduit, and other accessories. Wire the transmitter according to national, local and plant electrical requirements for the supply voltage. See Figure 19. Figure 19. DC Power Supply Current Requirements Supply Current (Amps) 0.9 0.8 0.7 0.6 0.5 0.4 0.3 0.2 12 18 24 30 42 36 Power Supply (Volts) I = Supply current requirement (Amps) V = Power supply voltage (Volts) Supply Wire Requirements Use 12 to 18 AWG wire rated for the proper temperature of the application. For connections in ambient temperatures above 140 °F (60 °C), use a wire rated for 176 °F (80 °C). For ambient temperatures greater than 176 °F (80 °C), use a wire rated for 230 °F (110 °C). For DC powered transmitters with extended cable lengths, verify that there is a minimum of 12 V DC at the terminals of the transmitter. Disconnects Connect the device through an external disconnect or circuit breaker. Clearly label the disconnect or circuit breaker and locate it near the transmitter and per local electrical control.

These parameters can be configured through either a local operator interface or a HART communication device. A table of all the parameters are on page 26. Descriptions of the more advanced functions are included in the comprehensive product manual. Basic Setup Tag Tag is the quickest and shortest way of identifying and distinguishing between transmitters. Transmitters can be tagged according to the requirements of your application. The tag may be up to eight characters long. Flow Rate Units The flow rate units variable specifies the format in which the flow rate will be displayed. Units should be selected to meet your particular metering needs. Line Size The line size (sensor size) must be set to match the actual sensor connected to the transmitter. The size must be specified in inches. URV (Upper Range Value) The upper range value (URV) sets the 20 mA point for the analog output. This value is typically set to full-scale flow. The units that appear will be the same as those selected under the units parameter. The URV may be set between –39.3 ft/s to 39.3 ft/s (–12 m/s to 12 m/s). There must be at least 1 ft/s (0.3 m/s) span between the URV and LRV. LRV (Lower Range Value) The lower range value (LRV) sets the 4 mA point for the analog output. This value is typically set to zero flow. The units that appear will be the same as those selected under the units parameter. The LRV may be set between –39.3 ft/s to 39.3 ft/s (–12 m/s to 12 m/s). There must be at least 1 ft/s (0.3 m/s) span between the URV and LRV. Calibration Number The sensor calibration number is a 16-digit number used to identify sensors calibrated at the Rosemount factory. 25 4664RevBBQIG.fm Page 26 Friday, January 11, 2013 6:13 PM Quick Installation Guide Rosemount 8712 / 8700 Series 00825-0100-4664, Rev BB January 2013 Table 11.
