Make the necessary adjustment by turning the range arm adjust screw counterclockwise if the pen is slightly underranged and clockwise if baton pen is slightly overranged.

Apply percent differential pressure to the highpressure housing of the DPU. This procedure should be performed prior to removing the DPU housing bolts, if the DPU has been installed in gas applications with working pressures greater than psig. The pen should indicate zero. The pen arm and shaft should rotate at the range arm pivot point without loosening the range arm lock screw.

Replacements made under this warranty will be shipped prepaid. Warranty NuFlo Technologies, Inc. The bellows are liquid filled and withstand overranges equal to the working pressure of the housing without calibration change. If the pen is high, shorten the linkage to make a correction 40 times as great in the high direction. Tighten the bolts and return the unit to the barto or authorized NuFlo service center for repair.


Mount the DPU on a suitable pipe stand and connect to a standard pressure source. Bartoh notes indicate the presence of a hazard which can cause severe personal injury, death, or substantial property damage if warning is ignored. Die-cast aluminum, black epoxy resin paint, waterproof and weather resistant hinged door; neoprene gasket seal DP Accuracy: Back off all housing bolts 4 turns. CAUTION notes indicate the presence of a hazard which can cause moderate personal injury or property damage if warning is ignored.

Rotate pen arm and shaft by gripping the range arm and bartkn or slipping the pen until it indicates zero.

Movement of the bellows is transmitted through a torque tube from the DPU to the recording mechanism. It’s a community-based project which helps to barhon anything. Upon such authorization, and in accordance with instructions by NuFlo Technologies, Inc.

Adapt a graduated degree scale to torque tube housing. Arrange the differential pressure linkage as shown on page Remove the DPU from service and remove the pressure housings.


Assure all linkage screws are retightened. The pointer attached baarton the torque tube shaft should indicate 8 degrees of travel. Carefully remove the pressure housings from the bellows unit assembly.

If the pen is low, lengthen the linkage to make a correction 40 times as great in the low direction. The DPU is a barrton bellows assembly enclosed within pressure housings.

Page 26 Section 5 – Installation Drawings Before installing this instrument, become familiar with the installation instructions in Section 2. Adapt a pointer to exposed end of the torque shaft. Check for internal pressure by attempting to move the housing in and out along the bolts. Page 13 Section 4 – Troubleshooting The torque tube is hermetically sealed to eliminate friction and leakage; it does not require lubrication.
