Reference Manual 00809-0200-4101, Rev AA July 2008 Impulse Piping Rosemount 2051 The piping between the process and the transmitter must accurately transfer the pressure to obtain accurate measurements. There are six possible sources of impulse piping error: pressure transfer, leaks, friction loss (particularly if purging is used), trapped gas in a liquid line, liquid in a gas line, and density variations between the legs.
Reference Manual 00809-0200-4101, Rev AA July 2008 Rosemount 2051 Mounting Requirements Impulse piping configurations depend on specific measurement conditions. Refer to Figure 2-8 for examples of the following mounting configurations: Liquid Flow Measurement • Place taps to the side of the line to prevent sediment deposits on the process isolators. • Mount the transmitter beside or below the taps so gases vent into the process line. • Mount drain/vent valve upward to allow gases to vent.
Reference Manual 00809-0200-4101, Rev AA July 2008 Process Connections Rosemount 2051 Coplanar or Traditional Process Connection Install and tighten all four flange bolts before applying pressure, or process leakage will result. When properly installed, the flange bolts will protrude through the top of the sensor module housing. Do not attempt to loosen or remove the flange bolts while the transmitter is in service.
Reference Manual 00809-0200-4101, Rev AA July 2008 Rosemount 2051 O-rings: The two styles of Rosemount flange adapters (Rosemount 1151 and Rosemount 3051/2051/2024/3095) each require a unique O-ring (see Figure 2-9). Use only the O-ring designed for the corresponding flange adaptor. Figure 2-9. O-Rings. Failure to install proper flange adapter O-rings may cause process leaks, which can result in death or serious injury. The two flange adapters are distinguished by unique O-ring grooves.
Reference Manual 00809-0200-4101, Rev AA July 2008 Rosemount 2051 Inline Process Connection Do not apply torque directly to the sensor module. Rotation between the sensor module and the process connection can damage the electronics. To avoid damage, apply torque only to the hex-shaped process connection. Sensor Module Process Connection Housing Rotation The electronics housing can be rotated up to 180 degrees in either direction to improve field access, or to better view the optional LCD display.
Reference Manual 00809-0200-4101, Rev AA July 2008 Rosemount 2051 LCD Display Transmitters ordered with the LCD option are shipped with the display installed. Installing the display on an existing 2051 transmitter requires a small instrument screwdriver. Figure 2-11. LCD Display . Jumpers (Top and Bottom) LCD Display Extended Cover Tagging Commissioning (Paper) Tag When commissioning more than one device on a fieldbus segment, it can be difficult to identify which device is at a particular location.
Reference Manual 00809-0200-4101, Rev AA July 2008 ELECTRICAL CONSIDERATIONS Rosemount 2051 NOTE Make sure all electrical installation is in accordance with national and local code requirements. Conduit Installation If all connections are not sealed, excess moisture accumulation can damage the transmitter. Make sure to mount the transmitter with the electrical housing positioned downward for drainage.
Reference Manual 00809-0200-4101, Rev AA July 2008 Rosemount 2051 Wiring Wiring and power supply requirements can be dependent upon the approval certification. As with all FOUNDATION fieldbus requirements, a conditioned power supply and terminating resistors are required for proper operation. The standard 2051 pressure transmitter terminal block is pictured in Figure 2-13. The terminals are not polarity sensitive. The transmitter requires 9-32 Vdc to operate.
Reference Manual 00809-0200-4101, Rev AA July 2008 Rosemount 2051 Perform the following procedure to make wiring connections: 1. Remove the housing cover on terminal compartment side. Do not remove the cover in explosive atmospheres when the circuit is live. Signal wiring supplies all power to the transmitter. 2. Connect the leads to the two FOUNDATION fieldbus wiring terminals. Refer to Figure 2-14. 3.
Reference Manual 00809-0200-4101, Rev AA July 2008 Rosemount 2051 NOTE The transient protection terminal block does not provide transient protection unless the transmitter case is properly grounded. Use the guidelines to ground the transmitter case. Refer to page 2-25. Do not run the transient protection ground wire with signal wiring as the ground wire may carry excessive current if a lightning strike occurs.

Reference Manual 00809-0200-4101, Rev AA July 2008 Rosemount 2051 HAZARDOUS LOCATIONS CERTIFICATIONS Individual transmitters are clearly marked with a tag indicating the approvals they carry. Transmitters must be installed in accordance with all applicable codes and standards to maintain these certified ratings. Refer to Appendix B: Approval Information for information on these approvals.
Reference Manual 00809-0200-4101, Rev AA July 2008 Rosemount 2051 Rosemount 305 Integral Manifold Installation Procedure To install a 305 Integral Manifold to a 2051 transmitter: 1. Inspect the PTFE sensor module o-rings. Undamaged o-rings may be reused. If the o-rings are damaged (if they have nicks or cuts, for example), replace with o-rings designed for Rosemount transmitter.
Reference Manual 00809-0200-4101, Rev AA July 2008 Rosemount 2051 Integral Manifold Operation Three-valve configuration shown. In normal operation the two isolate valves between the process and instrument ports will be open and the equalizing valve(s) will be closed. L H Drain/ Vent Valve Drain/ Vent Valve Equalize (closed) Isolate (open) Isolate (open) Process To zero the 2051, close the isolate valve to the low pressure (downstream side) of the transmitter first.
Reference Manual 00809-0200-4101, Rev AA July 2008 Rosemount 2051 The manifold valves are now in the proper configuration for zeroing the transmitter. To return the transmitter to service, close the equalizing valve(s) first. L H Drain/ Vent Valve Drain/ Vent Valve Equalize (closed) Isolate (open) Isolate (closed) Process Next, open the isolate valve on the low pressure side of the transmitter.
Reference Manual 00809-0200-4101, Rev AA July 2008 Rosemount 2051 LIQUID LEVEL MEASUREMENT Differential pressure transmitters used for liquid level applications measure hydrostatic pressure head. Liquid level and specific gravity of a liquid are factors in determining pressure head. This pressure is equal to the liquid height above the tap multiplied by the specific gravity of the liquid. Pressure head is independent of volume or vessel shape.
Reference Manual 00809-0200-4101, Rev AA July 2008 Rosemount 2051 Wet Leg Condition Condensation of the gas above the liquid slowly causes the low side of the transmitter piping to fill with liquid. The pipe is purposely filled with a convenient reference fluid to eliminate this potential error. This is a wet leg condition. The reference fluid will exert a head pressure on the low side of the transmitter. Zero elevation of the range must then be made. See Figure 2-20 Figure 2-20. Wet Leg Example.
Reference Manual 00809-0200-4101, Rev AA July 2008 Rosemount 2051 Bubbler System in Open Vessel A bubbler system that has a top-mounted pressure transmitter can be used in open vessels.
