For almost a century, ROOTS®
meters have been used for billing
of commercial and industrial gas
loads. Accuracy, dependability,
and low maintenance are of key
importance in custody transfer
measurement applications.
The time-proven ROOTS® meter
is the preferred rotary positive
displacement gas meter in
distribution, transmission and
production segments for accurate
measurement of gas from the
well to the burner.
To meet the evolving needs
of our customers, our product
line has expanded to include
a large variety of control and
measurement equipment.
ROOTS Meters & Instruments
is much more than just a meter
supplier. We offer a wide range
of ROOTS® products and services.

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.
As shown in the picture, two contra-rotating impellers of two-lobe or “figure 8” contour are encased within a rigid measuringchamber, with inlet and outlet connections on opposite sides.Precision machined timing gears keep the impellers in correctrelative position. Optimal operating clearances between theimpellers, cylinder and headplates provide a continuous, non-contacting seal.
ROOTS® meter product lineA 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.
