BETE® FlexFlow Precision Spray Control Systems for Automatic Spray Nozzles

BETE’s FlexFlow Spray Systems ensure precision control and flexible automation for our Electric
HydroPulse® and other automatic spray nozzles for use in Food Processing or any other industry
looking to save resources and improve product quality. These plug-and-play controllers are an
elegant solution for precision coating, moistening, and lubricating applications. Consider the
FlexFlow for any industrial process where expensive compounds or ingredients need to be sprayed
directly onto the process target. Each control panel can function as a standalone system. Our 2000
model features an Ethernet port to allow integration with your existing plant operations. Visit

SPRAY THE EXACT AMOUNT YOU NEED, PRECISELY WHEN YOU NEED IT

With FlexFlow precision spray control systems, you can activate spray zones using automatic
triggers such as photoelectric and proximity sensors, or make adjustments manually. Additional
trigger delay settings provide flexible parameters to reduce material consumption and minimize
cleaning maintenance by fine tuning the timing of the intermittent spray onto moving targets.

ACHIEVE UNIFORM COATING WITH PULSE WIDTH MODULATION

FlexFlow spray controllers achieve optimum spray precision by regulating the spray flow rate using
Pulse Width Modulation (PWM). With traditional single-fluid spray nozzles, the only way to adjust
the flow rate is by adjusting liquid supply pressure, which results in changes to spray performance
characteristics such as drop size and spray pattern. By comparison, PWM flow control works by
cycling spray nozzles on and off at high frequencies (up to 150 times per second). Adjusting the duty
cycle, or ratio of ON versus OFF dwell time, enables FlexFlow to control the average flow rate
without changing the supply pressure or spray performance characteristics. The high-frequency
operation ensures that spray coverage remains uniform, even when coating products on high-speed
conveyors.
