Encynova OEM System Modules-
Encynova System Modules are complete fluid delivery systems for metering and dispensing. These compact modules precisely move, control, and measure fluid.
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/driver.
Dispensing specs are based on tests with 1.0 mL of RO water
at room temperature and 1 atm of pressure.
* Please consult Encynova 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 ]

2-Series Model 2-1 Single-cylinder design; pulsation depends on control method.
Model 2-4 Nova 2-4 System includes NovaFlow™ for near-pulseless metering, and NovaSpense™ for dispensing accuracy up to 0.1% Cv. |

All dimensions shown in inches |
16-Series 16-series systems are recommended for applications with higher-viscosity fluids. Model 16-2
Model 16-4 Nova 16-4 System includes NovaFlow™ for near-pulseless metering, and NovaSpense™ for dispensing accuracy up to 0.1% Cv. |
Move it. Control it. Measure it.
Encynova 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.
