Gear Gas Flowmeters By Mass Flow Measurements Of Liquids

MUMBAI, India - May 20, 2013 - PRLog -- http://geargasflowmeter.blogspot.in/

GAS Geared Flow Meter OverviewA precision-machined, geared flow meter specifically designed and built for metering gases including air, carbon dioxide, and nitrogen.  Includes option for explosion-proof rating.

GAS  Geared Flow Meter Features• Simple construction for ease of maintenance and long meter life
• Ball bearings in the rotors permit measurement at low differential pressures
• A full range of remote instrumentation is available when equipped with a pulse generator
• EX version offers explosion proof rating including explosion-proof pulse generator
• Mass flow or flow rate under standard conditions available when combined with OVAL’s flow computer and density meter

Typical GAS OVAL Geared Flow Meter Applications• Air, nitrogen, carbon dioxide, city gas, LPG
• Not suitable for gases that come under high pressure gas safety regulations, corrosive gas, and oxygen

As a precisionflowmeter for gasmeasurement, thismeter has the sameconstruction of theOVAL general-purpose PD flowmeter forliquids, field proven foraccuracy and performance.
Specifically designedand built for gasservice, it has a precision-machinedmeasuring chamber.
Ideally suited formetering gases ingeneral, including air, CO2, and nitrogen.

■ FEATURES
1. A high degree of accuracy, thanks to its PD design with oval rotors.
2. With ball bearings that provide support for the rotors, it can measure with lowpressure differential.
3. Equipped with a multifunction electronic register (with LCD display), it comesin battery powered (dedicated to local indication), externally powered (pulsegenerator built in), explosionproof and non-explosionproof type, etc.
4. By selecting the right electronic register with a pulse generator, you can builda telemetering system that best meets your needs.
5. To ensure safety in telemetering, flameproof generators are available.
6. When combined with OVAL flow computer, continuous density meter or otherassociated equipment, mass flow measurement of gases or equivalent flowratemeasurement under  standard  conditions can  also  be achieved.
