THE ROOTS METER OPERATING PRINCIPLE

The ROOTS meter is designed to measure the volume of gases and gas mixtures with a high degree of accuracy. The industry accepted rotary type positive displacement operating principle ensures permanent, non-adjustable accuracy by using precision machined two-lobe impellers encased within a rigid measuring chamber.

Unlike other meter types, measurement accuracy is not affected by changes in gas specific gravity, pressure, or fluctuating flow. ROOTS meters may be used from a few ounces to full capacity up to the meter's maximum pressure rating with highly accurate measurement over a wide operating range. This equates to a lower total cost.

The condition of a ROOTS rotary meter can be verified by performing a differential rate test while the meter is still in service. This simple and cost-effective preventive maintenance procedure contributes to a significant reduction in the wholelife cost of the meter.

A complete line of rotary meter sizes are available to measure a wide range of gas volumes for the majority of commercial and industrial applications in custody transfer applications. Refer to the Meter Sizing Chart in this brochure to determine the correct meter size for cost effectiveness and accurate measurement.

ROOTS meters are suitable for handling most types of clean, common gases at either constant or varying flow rates and pressure. They are ideal for applications throughout the meter's operating range, from a few ounces to full maximum allowable operating pressure.

Our meters are widely recognized for their highly accurate measurement capabilities at both the low and high end of their rated capacity. The meter's rangeability (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.
