The DPU is a dual bellows assembly enclosed within pressure housings. Arrange the differential pressure linkage as shown on page If the pen is low, lengthen the linkage to make 202r correction 40 times as great in the low direction.
It’s a community-based project which helps to repair anything. CAUTION notes indicate the presence of a hazard which can cause moderate personal injury or property damage if warning is ignored.

bsrton Die-cast aluminum, black epoxy resin paint, waterproof and weather resistant hinged door; neoprene gasket seal DP Accuracy: Tighten the bolts and return the unit to the factory or authorized NuFlo service center for repair.
The bellows are liquid filled and withstand overranges equal to the working pressure of the housing without calibration change. Assure all linkage screws are retightened.
WARNING notes indicate the presence of a hazard which can cause severe personal injury, death, or substantial property damage if warning is ignored. Back off all housing bolts 4 turns.
The pointer attached to the torque tube shaft should indicate 8 degrees of travel. Replacements made under this warranty will be shipped prepaid. Adapt a pointer to exposed end of the torque shaft. Upon such authorization, and in accordance with instructions by NuFlo Technologies, Inc. The torque tube is hermetically sealed to eliminate friction and leakage; it does not require lubrication.

Apply percent differential pressure to the highpressure housing of the DPU. The pen should indicate zero. If the pen is high, shorten bartton linkage to make a correction 40 times as great in the high direction.
Rotate pen arm and shaft by gripping the range arm and forcing or slipping the pen until it indicates zero. Warranty NuFlo Technologies, Inc. The pen arm and shaft should rotate at the range arm bartoh point without loosening the range arm lock screw. Page bartn Section 5 – Installation Drawings 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.

Adapt a graduated degree scale to torque tube housing. Page 13 Section 4 – Troubleshooting Check for internal pressure by attempting to move the housing in and out along the bolts.
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. Carefully remove the pressure housings from the bellows unit assembly.
Before installing this instrument, become familiar with the installation instructions in Section 2. 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. Movement 2202e the bellows is transmitted through a torque tube from the DPU to the recording mechanism.
