Dispensing specs are based
on tests with 1.0 mL of RO water at room temperature and
1 atm of pressure.
* Please consult Car-May for information specific to your
application.
* * Specifications are dependent on control system used.
* * * For flow rates of less than 1 mL/min the calculated
instantaneous pulsation levels increase.
Observed pulsation levels depend greatly on fluidic setup
and measurement technique.
Cv: The coefficient of variation, expressed in percent,
is used to describe the standard deviation
(s) relative to the mean (X). Cv = [ (100) (s)/ X ] |

Wetted
Materials
The wetted parts of "Standard configuration"
Car-May System Modules are made from chemically-resistant
materials, creating a versatile, durable fluid control
system. For applications that involve more aggressive
fluids, an even more robust "Inert" wetted parts option
is available. Other options may be available- please
contact us about your 'problem liquid.'

Nova
System Communications
To harness precision, you must have control.
| |
|
|
|
That's why our Nova Systems have
a flexible communications platform. RS-485 communication
capability allows you to easily control the Nova
Systems with our predefined commands. Use a PC,
PLC, or any other source that can generate 8-bit
ASCII commands to precisely control as many Nova
Systems as you need.
LabVIEW™, C++ and Visual Basic
compatibility provide the versatility required
for simple and effective integration into your
process. Connect the Nova System, assign it to
an address on your network, and you are ready
to go. Up to 250 Modules can be controlled on
one RS-485 network using ASCII serial strings.
Digital I/O and analog capability are standard
in Nova Systems and in Basic Systems that use
the integrated motor/drive. |
|
Move it. Control it. Measure it.
Car-May systems are different from
basic pumps because they do more than typical
pumps. Measurement and flow control capabilities
are incorporated into the pump's design. No external
valves or flow meters are needed.
