Cameron's Barton 7000 Series Liquid Turbine Meters - 25235 7000 SeriesLiquid Turbine Meters
Models 71xx, 72xx, & 73xx
Low mass design : The small lightweight rotor hubsboth ensure fast response to processflow changes and reduced bearing
load and wear. On meters above 2-in. (50 mm) the hub is eitherhollow or indented to further reduce
the rotating mass.• Low maintenance : True fluid thrust design hydro-
dynamically balances the rotorduring operation. This unique design eliminates the need for
mechanical thrust leveling. This low
friction design both improvesmetering linearity and reduces wear and maintenance. Barton
® 7000 series turbines aredesigned for a broad range of precise
liquid measurement applications. Based
on 35 years of turbine manufacturing,
this built-to-order series features a
range of sizes, materials, bearingsystems, and options. • Wide rangeability : 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 thesame in either direction. Electronicoptions provide instantaneous flow
direction sensing.• Wide temperature and pressure ranges : Measurement options for hot hydro-
carbon to cryogenic applications.• High quality bearings : Wear resistant tungsten carbide
sleeve bearings standard on 71xx/73xx meters and self-lubricating,precision stainless steel bearings (dry lubricant impregnated ballseparators on 72xx meters).

Features
• Linearity : Better than ±1% of reading overlinear flow range of fractional sizemeters. Better than ±0.25% of
reading over linear flow range of
meters 1-in. size and above.• Repeatability : ±0.02% of reading.• Compact and efficient : Compared to other metering
techniques, Barton
® turbine metersare able to handle a larger flowratein a smaller meter and with a lowerpressure drop. With the use of
reduced diameter block
valves andmeter runs,substantial installed cost savings are achieved.• Self-flushing design : Longer sustained accuracy.• High frequency digital output :Easy interface with digital
equipment.
