Roots® Meters & Instruments, a part of Dresser Natural Gas Solutions, manufactures Roots rotary positive displacement meters, electronic instruments and accessories.

For almost a century, Roots meters have been used for billing of commercial and industrial gas loads. Accuracy, dependability, and low maintenance are key factors in custody transfer measurement applications. The time-proven Roots meter is the preferred gas meter in the distribution, transmission and production segments of the natural gas industry for accurate measurement of gas from the well to the burner.

Our product line includes a large variety of control and measurement equipment, and we offer a wide range of Roots products and services. Based in Houston, Texas, Roots Meters & Instruments maintains a global network of sales offices, local representatives and distributors to meet the needs of our customers.
 
 


 		 Roots Meters & Instruments offers a complete line of rotary meter sizes to measure a wide range of gas volumes for the majority of commercial and industrial applications in custody transfer applications. Refer to a Meter Sizing Chart to determine the correct meter size for cost effectiveness and accurate measurement. When selecting a meter size for your application, use the minimum operating pressure and maximum instantaneous flow rate.

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 accuracy on a "day-after-day" basis.

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

For further versatility, the five smallest meter sizes (8C through 3M) have 2" (50 mm) flanged connections, and a 6-3/4" (171 mm) flange-to-flange dimension. If application requirements change, this unique, cost-effective feature allows a quick and easy meter exchange without the need to re-pipe the meter set.

Other key features include:
  • Capacity ratings from 800 CFH to 56,000 CFH
    (22,6 m³/h to 1,600 m³/h)
     
  • Maximum operating pressure rating of 175 PSIG
    (12 Bar)
     
  • Models 8C through 2M available with a 200
    PSIG (13,8 Bar) rating upon request
     
  • Operating temperature range from -40º to +140F
    (-40ºC to +60ºC)
