Back off all housing bolts 4 turns.

Assure all linkage screws are retightened. Die-cast aluminum, black epoxy resin paint, waterproof and weather resistant hinged door; neoprene gasket seal DP Accuracy: Before installing this instrument, become familiar with the installation instructions in Section 2.

Carefully remove the pressure housings from the bellows unit assembly.

Warranty NuFlo Technologies, Inc. Page 13 Section 4 – Troubleshooting Rotate pen arm and shaft by gripping the range arm and forcing or slipping the pen until it indicates zero. Adapt a graduated degree scale to torque tube housing. The pen should indicate zero.

The torque tube is hermetically sealed to baarton friction and leakage; it does not require lubrication. Adapt a pointer to exposed end of the torque shaft.


Apply percent differential pressure to the highpressure housing of the DPU. Replacements made under this warranty will be shipped prepaid. It’s a community-based project which helps to repair anything. Movement of the bellows is transmitted through a torque tube from the DPU to the recording mechanism.

If the pen is high, shorten the linkage to make bqrton correction 40 times as great in the high direction.

Arrange the differential pressure linkage as shown on page Tighten the bolts and return the unit to the factory or authorized NuFlo service center for repair. This procedure should be performed prior to removing the DPU bartoh bolts, if the DPU has been installed in gas applications with working pressures greater than psig.

Mount the DPU on a suitable pipe stand and connect to a standard pressure source. Make the necessary adjustment by turning the range arm adjust screw counterclockwise if the pen is slightly bartoon and clockwise if the pen is slightly overranged.

If the pen is low, lengthen the linkage to make a correction 40 times as great in the low direction.

Check for internal pressure by attempting to move the housing in and out along the bolts. The bellows are liquid filled and withstand overranges equal to the working pressure of the housing without calibration change. CAUTION notes indicate the presence of a hazard which can cause moderate personal injury or property damage if warning is ignored.

Upon such authorization, and in accordance with instructions by NuFlo Technologies, Inc. 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 pen arm and shaft should rotate at the range arm pivot point without loosening the range arm lock screw.

The pointer attached to the torque tube shaft should indicate 8 degrees of travel.
