8C/11C/15C (Image Above)
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.
2M/3M/5M (Image Below)
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.
7M/11M/16M (Image Below)
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).

23M232 (Image Above)
Our new 23M232 includes four inch flanged connections
and a 232 PSIG (16 bar) maximum working pressure.
This new design complements our standard six inch
23M175. With a maximum capacity of 385 MSCFH
(10,895 Nm3 per hour) the new 23M232 is an ideal
measurement solution for wide array of applications.
Series B3-HPC (Image Above)
Series
B3-HPC (High Pressure Cartridge) Meters
This meter line features a common cast-steel housing for the 1M
(1000 ACFH) and 3M (3000 ACFH) sizes of aluminum cartridges. The meters are available with
either an ANSI Class 300# flange (740 PSIG) or an ANSI Class 600# flange (1480 PSIG).The
cartridges are field replaceable and are interchangeable between housings regardless of
the pressure rating on the housing. As an option, a self-resetting full flow internal
bypass is available on new meters and on replacement cartridges. Since this meter utilizes
the Series 3 Accessory Units, a full line of index options are available.

Series B3-HP
(High Pressure) Meters (Image Above)
For lower pressure loads, the 1M300 (1000 ACFH) and 3M300 (3000 ACFH) are viable
alternatives for pressures up to 300 PSIG. Based on the B3 meter line, the B3-HP meters
offer extremely low start and stop rates and a compact design with a 6-3/4" flange-to-flange dimension and a much lower weight than traditional high pressure meters.
This is achieved by using aluminum for all major meter components. The Series B3-HP meters
mate with ANSI 300# flanges and are easily installed by one person without the need for a
lift or hoist.
7M1440 High Pressure Meter (Image Above)
7M1440 meters are designed for higher capacity applications (7000 ACFH) with a maximum
allowable operating pressure of 1440 PSIG. The materials of construction are cast ductile
iron and cast steel to meet the demands of the higher flow rates and pressures.
Series Z Compact Meters (Image Above)
Ideal for small commercial loads at pressures up to 15 PSIG (1 Bar), the aesthetically
pleasing 5C15 (500 ACFH) and 8C15 (800 ACFH) meters are easy to install and conceal.
Series Z meters provide excellent measurement accuracy starting at "pilot loads" and continuing throughout the range of the meter. To match the meter configuration to the
application, the user selects the following parameters
when ordering:
Series A (LM-MA) (Image on left)
The 8C175 compact meter, like the Series Z, is also ideal for small commercial
applications, but with a higher pressure rating. This meter is rated for a 175 PSIG (12
Bar) working pressure.
Series A1 Foot Mount Meter (Image on left)
The 102M125 Foot Mount meter is used for the measurement of high volume industrial gas
loads for capacities up to 965.3 MSCFH at 125 PSIG (27,941 Nm³/h at 8,6 Bar).
B3-VRM
Vapor Recovery Meter (Image on right)
Rated for a maximum capacity of 3000 actual cubic feet per hour, the B3-VRM meters are
specifically designed and tested for vapor recovery applications and conform to the
California Air Resources Board specifications TP-201.1, TP-201.1A, TP-201.2, and TP-201.5,
as applicable. The extremely low pressure drop associated with the ROOTS positive
displacement meter makes this meter ideal for the accurate measurement in low pressure
recovery systems. Odometers on the vapor recovery meters are marked at 0.02 cubic foot
increments, which allows accurately estimated readings in increments of 0.01 cubic feet.
All B3-VRM meters are supplied with a 7 point certified accuracy curve for reference.
