The Dresser Series B3 Roots meter is a positive displacement, rotary type gas meter designed for continuous and accurate gas measurement. Considered a standard for both commercial and industrial applications, the Roots meters are suitable for handling most types of clean, dry, common gases at either constant or varying flow rates. Meters of standard construction are not directly suitable for handling acetylene, biogas or sewage gas but specially constructed meters are available for order to meet the challenges of your specific application.
Volumetric accuracy of the Roots meter is permanent, non-adjustable, and is not affected by low or varying line pressure. Dresser Series B3 meters may be used for pressures ranging from a few ounces to the full Maximum Allowable Operating Pressure (MAOP). Displaced volume measurement is completely independent of the gas specific gravity, temperature, and pressure.
Dresser Series B meters have a MAOP rating of 175 psig (1200kPa). Every meter is static pressure tested at the factory at twice its MAOP and leak tested at 125 percent of MAOP in accordance with ASME Boiler Pressure Vessel Codes. Other pressure ratings are available to order.
Dresser meters are manufactured in accordance with ANSI B109.3 for Rotary Type Gas Displacement Meters. Dresser Series B3 meter sizes 8C through 56M, have flanged inlet and outlet connections conforming dimensionally with ANSI/ASME standards. Sizes 8C through 2M are available with 1-1/2” NPT connections, upon special request. The meter operating temperature range is from -40°F to +140°F (-40°C to +60°C) while the temperature compensating mechanism of the mechanical TC accessory provides a corrected reading for temperatures ranging from -20°F to +120°F (-29°C to +49°C).
