Automatic paint sprayers, like those used in the automotive industry, require a constant flow of gas and paint to evenly apply a coat of paint to a surface. While atomizing the paint, the amount gas and paint supplied to the electric field can be adjusted to shape the stream of paint. This creates a consistent, quality finish.
Consistency between runs of the robotic painting system is vital. Different paint colors have differing properties, like weight, therefore different pressures and flow rates are needed to achieve the same shape. Repeatability and consistency of the flow rate are critical to ensure an even coat in all colors.
Alicat mass flow controllers have a repeatability of ± (0.1% of reading + 0.02% of full scale). They are also calibrated against a NIST traceable standard to ensure that every device is within our stated accuracy of ± 0.6% of reading.
With protocol choices like EtherNet/IP and EtherCAT, it’s easy to automate the process of changing colors without changing the shape of the stream.
