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
