Overview

BARTON Series 7400 gas turbine flowmeters are designed for gas service in a wide range of industrial, commercial, pipeline, and aerospace applications. Because the output from the pickup coil is digital, our range of BARTON Series 7000 liquid turbine flowmeters are a perfect match for electronic output devices because no A/D conversion is required. For the BARTON 7400 Series gas turbine flowmeters specifically, the rotor response is in milliseconds, providing precise metering in rapidly changing flow pattern applications.

Specifications

Standard Features
  • High Accuracy – Custody transfer quality measurements have ±0.2% of flow-rate repeatability and a single K-factor linearity of better than ±1.0% of reading over flow range
  • Wide Application – Able to meter gases from oxygen to ethylene for natural gas production, gas transmission, petrochemical, transport, aerospace, and petroleum production/refining industries
  • Responsive – A major advantage over other primary flow devices, the rotor response in milliseconds provides precision even in rapidly changing environments
  • High-Frequency Digital Output – Easy interface with digital equipment
  • Wide Range – Eliminates parallel runs and the cost of extra valves and strainers
  • Symmetrical Bi-Directional Design – Ideal for reverse flow applications since accuracy and flow capacities are the same in either direction; Electronic options provide instantaneous flow direction sensing
  • Wide Temperature and Pressure Ranges – Measurement options for hot hydrocarbon to cryogenic applications
  • Compact and Efficient – Compared to other precision metering techniques, our BARTON turbine meters can handle a larger flow rate in a smaller meter and at a lower pressure drop; With the use of reduced diameter block valves and meter runs, substantial installation cost savings are achieved
  • Low-Mass Design – The small, lightweight rotor hubs ensure fast response to process flow changes and reduced bearing load and wear; For meters above 2", the hub either is hollow or indented to further reduce the rotating mass
  • Low Maintenance – Sealed self-lubricating bearings feature a maintenance-free 10-year design life
  • Integral Pressure Tap – Precisely positioned to accommodate pressure measurement at the turbine meter
