BARTON® Model 202E Flow Recorder

 

BARTON chart recorders are the industry standard for accurate, reliable measurement and recording of

pressure differential pressure and temperature pressure, pressure, in a wide variety of applications. In addition, DP models

utilize rupture?proof bellows DPU as the actuating unit — with features like overrange protection and

pulsation dampening (on some models).

 

The 202E is a 12-inch chart recorder that has been widely used in gas transmission and distribution fields

– accurate calibration, even under extreme variations in static pressure and ambient temperatures. The

202E is available in 1 to 4 pen configurations (DP+3 additional pens). The additional pens can be used to

record temperature and supplemental pressure data. The unit is actuated by a BARTON Model 199 DPU,

with standard and NACE units available (up to 6,000 PSI/414 bar SWP) — see DPU bulletin #21700 for

details. Static pressure and temperature pens are actuated by precision wound elements.
