IMPORTANT NOTICE

This document provides basic installation guidelines for the Rosemount® 8712. 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 number00809-0100-4664)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-Rosemountsensor 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-woundgaskets. 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.

Environmental Considerations

To ensure maximum transmitter life, avoid excessive heat and vibration. Typical problem areas include:

Warm-climateinstallations 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 4–20mA 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-selectablehardware 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.

STEP3: 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-sectionalarea 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.

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.

STEP4: INSTALLATION

Flanged Sensors

Gaskets

The sensor requires a gasket at each of its connections to adjacent devices or piping. The gasket material selected must be compatible with the process fluid and operating conditions. Metallic or spiral-woundgaskets 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) andTable 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 inFigure 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.

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.
