SECTION 1 - INTRODUCTION

General

The Barton

®

 Model 202E single DP Flow Recorders measure and record system

operation parameters including gas and liquid flow rate, liquid level in a vessel,

and other system variables that can be measured by differential pressure and

static pressure methods.

Main Components

Differential Pressure Unit

The Barton

®

 Model 199 Differential Pressure Unit (DPU) actuates the recorders.

The DPU is a dual bellows assembly enclosed within pressure housings. The

bellows are liquid filled and withstand overranges equal to the working pressure

of the housing without calibration change. Movement of the bellows is transmit-

ted through a torque tube from the DPU to the recording mechanism. The

torque tube is hermetically sealed to eliminate friction and leakage; it does not

require lubrication.

Before installing this instrument, become familiar with the installation instructions

in Section 2. WARNING notes that appear on the following pages of this manual

should be reviewed before proceeding: 8, 20, 21, 22, and 25.

SAFETY 

!

WARNING notes indicate the presence of a hazard which can cause severe personal injury, death, or substantial

property damage if warning is ignored.

CAUTION notes indicate the presence of a hazard which can cause moderate personal injury or property

damage if warning is ignored.
