BARTON Series 7400 Gas Turbine Meter
Overview :
Cameron' s BARTON® 7400 series precision turbine meters 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, BARTON 7000 series meters are a perfect match for electronic output devices — no A/ D conversion required. The rotor response is in milliseconds, providing precise metering in rapidly changing flow pattern applications.
Specifications :
- Standard Features High Accuracy
- Custody transfer quality measurements with ± 0.2% of flowrate repeatability and a single
K-factor linearity of better than ± 1.0% of reading over flow range. Wide Application.
- Metering of 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. Rotor response in milliseconds provides
precision even in rapidly changing environments. High Frequency Digital Output
- Easy interface with digital equipment. Wide Range ability
- Eliminates parallel runs and the cost of extra valves and strainers. Symmetrical bi-directional
design
- Ideal for reverse flow applications, 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, Barton turbine meters are able to 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 both ensure fast response to process flow changes and
reduced bearing load and wear. For meters above 2" ( 50 mm) , the hub is either 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.
