Barton Chart Recorders E/E/J8A, formerly known as ITT Barton Recorders, is the leader for recording of DP (Differential Pressure), pressure. The Barton Instruments E is a chart recorder that is used in gas transmission and distribution fields. It is an inch accurate calibration unit that even works.

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. 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.
Check for internal pressure by attempting to move the housing in and out along the bolts. Before installing this instrument, become familiar with the installation instructions in Section 2. Movement of the bellows is transmitted through a torque tube from the DPU to the recording mechanism.
Page 26 Section 5 – Installation Drawings 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. Apply percent differential pressure to the highpressure housing of the DPU. 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.
Mount the DPU on a suitable pipe stand and connect to a standard pressure source. WARNING notes indicate the presence of a hazard which can cause severe personal injury, death, or substantial property damage if warning is ignored. Adapt a graduated degree scale to torque tube housing.

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 DPU is a dual bellows assembly enclosed within pressure housings.

Carefully remove the pressure housings from the bellows unit assembly. Die-cast aluminum, black epoxy resin paint, waterproof and weather resistant hinged door; neoprene gasket seal DP Accuracy: The pointer attached to the torque tube shaft should indicate 8 degrees of travel.
Adapt a pointer to exposed end of the torque shaft. If the pen is low, lengthen the linkage to make a correction 40 times as great in the low direction.
Arrange the differential pressure linkage as shown on page If the pen is high, shorten the linkage to make a correction 40 times as great in the high direction.
Remove the DPU from service and remove the pressure housings.
The bellows are liquid filled and withstand overranges equal to the working pressure of the housing without calibration change. It’s a community-based project which helps to repair anything.
