Dresser Rotory Displacement Gas Meter
The Dresser Meter is designed to measure the volume of gases and gas mixtures with a high degree of accuracy. The industry accepted rotary positive displacement operating principle ensures permanent, non-adjustable accuracy by using precision machined two-lobe impellers encased within a rigid measuring chamber.
Dresser Meters are recognized for highly accurate measurement from Qmin to Qmax. The meter’s rangeability, the ability to measure gas over a wide flow range within a specified accuracy, provides the best over-all measurement accuracy on a “day-after-day” basis, not just laboratory testing. Our meters are designed to provide accurate gas measurement over widely fluctuating flow, pressure, and temperature conditions.
Unlike other meter types, measurement accuracy is not affected by changes in specific gravity, pressure, or fluctuating flow. Dresser Meters may be used from a few ounces up to full capacity of the meter’s maximum pressure rating with highly accurate measurement over a wide operating range. This equates to a lower total cost.
