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. Adapt a pointer to exposed end of the torque shaft. It’s a community-based project which helps to repair anything. The pointer attached to the torque tube shaft should indicate 8 degrees of travel.
Assure all linkage screws are retightened. The DPU is a dual bellows assembly enclosed within pressure housings. Adapt a graduated degree scale to barhon tube housing. Replacements made under this warranty will be shipped prepaid.
If the pen is high, shorten the linkage to 022e a correction 40 times as great in the high direction. Page 13 Section 4 – Troubleshooting Apply percent differential pressure to the highpressure housing of the DPU.
Arrange the differential pressure linkage as shown on page If the pen is low, lengthen the linkage to make a correction 40 times as great in bsrton low direction. Warranty NuFlo Technologies, Inc. Make the necessary adjustment by turning the range arm adjust screw counterclockwise if the pen is slightly underranged and clockwise if the pen is slightly overranged. Before installing this instrument, become familiar with the installation instructions in Section 2.
The pen should indicate zero.
Tighten the bolts 202w return the unit to the factory or authorized NuFlo service center for repair. Carefully remove the pressure housings from the bellows unit assembly.

Rotate pen arm and shaft by gripping the range arm and forcing or slipping the bbarton until it indicates zero. The torque tube is hermetically sealed to eliminate friction and leakage; it does not require lubrication.
Page 26 Section 5 – Installation Drawings WARNING notes indicate the presence of a hazard which can cause severe personal injury, death, or substantial property damage if warning is ignored. The bellows are liquid filled and withstand overranges equal to the working pressure of the housing without calibration change.

Check for internal pressure by attempting to move the housing in and out along the bolts. The pen arm and shaft should rotate at the range arm pivot point without loosening the range arm lock screw.
Mount the DPU on a suitable pipe stand and connect to a standard pressure source. Remove the DPU from service and remove the pressure housings.
