Dresser Roots Meters - Series B3

The ROOTS Meter Series B3 is a positive displacement, rotary type gas meter designed for continuously measuring and indicating the accurate measurement of gas in a pipeline. 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 directly 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 B meters may be used satisfactorily for pressure 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/ASC-B1 09.3 for Rotary Type Gas Displacement Meters. ROOTS Meter Series B 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).

ROOTS Meters Series B have a Maximum Allowable Operating Pressure (MAOP) rating of 175 psig (1200 kPa). 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.

Roots Series B meter bodies accept a wide range of Series 3 accessories for all metering applications

Counter Pulser & TC Versions

Full Range of Sizes:
12 meter sizes offer a complete range of rotary meters for commercial and industrial metering applications. Select the correct meter size for cost effectiveness and accurate measurement.

Standardized Flanges:
Sizes BC through 5M have a 6-3/4" (171 mm.) flange-to-flange dimension for standardization in the meter set design. As loads change, meter sizes can be easily interchanged, saving the cost of re-piping.

Accurate Low Flow Performance:
Low start/stop rates extend the rangeability (gas measured) over a wider range of flow conditions.

Low Pressure Differentials:
Reducing the maximum operating speed provides lower pressure differentials for low pressure applications, as well as extending the meter's life-expectancy.
    

SERIES 3 ACCESSORY UNITS

New Oil-Free Design:
Series 3 accessories feature high quality and long-term reliability with an oil-free, permanently lubricated design. Oil is not required for the Polymer bushings and pre-lubricated, shielded ball bearings. Permanent lubrication equates to easier installation and less
maintenance.

Durable, Weather Resistant Cover:
Optical Quality Lexan covers on Series 3 accessories offer optimal Ultraviolet protection while the cylindrical design allows the unit to easily shed rain, snow, ice, and dirt. The single piece cover design provides added protection against leakage under extreme conditions.

Solid State Pulser Installation Is A Snap:
ROOTS Meters with factory installed Solid State Pulsers are the low cost solution for your AMR requirements. With magnets installed, the pulser assembly literally snaps onto the cover without removing the meter from service. Pulser-ready meters are an economical factory option.

New Non-Moving Odometer Masking System:
A unique and versatile odometer masking design using opaque or semi-transparent covers offers configurable, trouble-free masking.

Universal Instrument Drive Assembly:
One size fits all with the Series 3 Instrument Drive assembly. Inventory costs are reduced by stocking one ID Assembly.
