DeltaMatic Linebreak Systems

Introduction

The Bettis^® DeltaMatic™ linebreak detection system is designed to automatically monitor a gas pipeline and send an instrument pressure signal if a predetermined rate of pressure drop is exceeded. The system is typically used to detect a pipeline break situation and signal a valve operator. This automatic shutdown function provides safety and environmental protection in populated areas, river crossings, remote areas and other locations.
 

Typical Applications

• Rate of Drop linebreak in gas pipelines

Key Features

• Works on pipeline pressure, no electrical power required
   
• Allows normal pipeline pressure fluctuations without shutdown
   
• Compact and assembled as a complete unit
   
• Can be retrofitted into an existing system with minimal field hook–up
   
• Can be installed remote from or directly on valve operator
   
• Uses a labyrinth type flow restriction (restrictor) providing a large passage size compared to an equivalent orifice or metering valve
   
• Standard rate of drop ranges down to 5 and up to 120 psig/minute
   
• Rate of drop setting can be easily field adjusted
   
• Functions in extreme cold environment to –50°F [–46°C]
