Flow Meters (MA,
MB, MS)
The following optional flow meters are available from Graco:
• G3000 is a general purpose gear meter typically used in flow ranges of 75-3800
cc/min. (0.02–1.0 gal/min.), pressures up to 4000 psi (28 MPa, 276 bar), and viscosi-
ties of 20–3000 centipoise. The K-factor is approximately 0.119 cc/pulse.
• G3000HR is a high resolution version of the G3000 meter. It is typically used in flow
ranges of 38–1900 cc/min. (0.01–0.5 gal/min.), pressures up to 4000 psi (28 MPa,
276 bar). and viscosities of 20–3000 centipoise. The K-factor is approximately 0.061
cc/pulse.
• G250 is a general purpose gear meter, used in RoboMix systems. It is typically used
in flow ranges of 75-3800 cc/min. (0.02–1.0 gal/min.), pressures up to 300 psi (2.1
MPa, 21 bar), and viscosities of 20–3000 centipoise. The K-factor is approximately
0.119 cc/pulse.
• G250HR is a high resolution version of the G250 meter, used in RoboMix systems. It
is typically used in flow ranges of 38–1900 cc/min. (0.01–0.5 gal/min.), pressures up
to 300 psi (2.1 MPa, 21 bar). and viscosities of 20–3000 centipoise. The K-factor is
approximately 0.061 cc/pulse.
• S3000 is a gear meter used for solvents in flow ranges of 38-1900 cc/min. (0.01–0.50
gal/min.), pressures up to 3000 psi (21 MPa, 210 bar), and viscosities of 20–50 centi-
poise. The K-factor is approximately 0.021 cc/pulse. Required to use the Solvent
Push feature.
• Coriolis is a specialty meter capable of a wide range of flow rates and viscosities.
This meter is available with 1/8 in. or 3/8 in. diameter fluid passages. For detailed
information on the Coriolis meter, see manual 313599.
The K-factor is user-settable; at lower flow rates use a lower K-factor.
➜ 1/8 in. fluid passages: set K-factor to .020 or .061.
➜ 3/8 in. fluid passages: set K-factor to .061 or 0.119.
Color Change
Valves (ACV) and
Color Change
Module (CCM)
An optional component. It is available as a color change valve stack for either low or high
pressure with up to 30 color change valves. Each stack includes one additional valve for
solvent to clean the fluid line between color changes.
Catalyst Change
Valves (BCV)
An optional component. It is available as a catalyst change valve stack for either low or
high pressure with up to 4 catalyst change valves. Each stack includes one additional
valve for solvent to clean the fluid line between catalyst changes.
Dual Fiber Optic
Cable (FO)
Used to communicate between the EasyKey and Wall Mount Fluid Station or RoboMix.
Fluid Station Power
Supply Cable (PS)
Used to provide power to the Wall Mount Fluid Station or RoboMix.
Flow Control
Regulator
Assembly (FC)
Includes an air operated fluid pressure regulator, fluid pressure sensor, voltage to air
pressure transducer and circuit board. The function of this unit is to receive the flow ana-
log signal and drive (manage) the desired flow rate.
