    The Series B3 ROOTS® meter is a positive displacement, rotary type gas meter
    designed for continuously measuring and indicating the accurate measurement of
    gas. 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. Contact the
    factory for information on specially constructed meters made of materials more
    compatible with these and other gases.
    Volumetric accuracy of the ROOTS® meter is permanent, non-adjustable, and
    is not affected by low or varying line pressure. Series B3 meters may be used
    satisfactorily for pressures ranging from a few ounces to full MAOP. Displaced
    volume measurement is completely independent of the gas specific gravity,
    temperature, and pressure.
    ROOTS® meters are manufactured in accordance with ANSI B109.3 for Rotary
    Type Gas Displacement Meters. Series B3 ROOTS® 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 TC accessory provides a corrected reading for temperatures
    ranging from -20°F to +120°F (-29°C to +49°C).
    Series B ROOTS® meters have a Maximum Allowable Operating Pressure
    (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.
