  • Page 5 Quick Start Guide February 2014 Environmental considerations To ensure maximum transmitter life, avoid extreme temperature and excessive vibration. Typical problem areas: high-vibration lines with integrally mounted transmitters  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.
  • Page 6 February 2014 Quick Start Guide Hardware jumpers/switches The 8750W electronics board is equipped with user-selectable hardware switches depending on the transmitter model ordered. These switches set the Failure Alarm Mode, Internal/External Analog Power, Internal/External Pulse Power and Transmitter Security. The standard configuration for these switches when shipped from the factory is as follows: Failure Alarm Mode: HIGH...

    Quick Start Guide February 2014 Step 2: Handling Handle all parts carefully to prevent damage. Whenever possible, transport the system to the installation site in the original shipping containers. Rosemount flow sensors are shipped with end covers that protect it from mechanical damage. For PTFE lined sensors the cover also prevents normal liner relaxation.

  • Page 8: Mounting

    February 2014 Quick Start Guide 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 Figure 4 diameters downstream from the electrode plane (see Figure 4.
  • Page 9 Quick Start Guide February 2014 The sensor should be installed in a location that ensures it remains full during operation. Vertical installation with upward process fluid flow keeps the cross-sectional area full, regardless of flow rate. Horizontal installation should be restricted to low piping sections that are normally full.

  • Page 10: Installation

    February 2014 Quick Start Guide Step 4: 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. 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.
  • Page 11 Quick Start Guide February 2014 Flange bolts Do not bolt one side at a time. Tighten each side simultaneously. Example: 1. Snug upstream 2. Snug downstream 3. Tighten upstream 4. Tighten downstream Do not snug and tighten the upstream side and then snug and tighten the downstream side.

  • Page 22 February 2014 Quick Start Guide Connecting 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 0.51mm diameter (#24 AWG) for cable runs less than 1,500 meters (@ 5,000 ft.) and 0.81mm diameter (#20 AWG) for longer distances.
