Sequoia Scientific - Model FlowControl-Lab -3-way Valve System

• Periodically filtered measurements allow for high-accuracy differential measurements of particle properties
• Electrically-actuated three-way ball valve allows flow to be bypassed through submicron filter cartridge before instrumentation
• Includes valve, power supply, controller, one paddlewheel flow sensor, cables, and Windows software
• Valve position indicator
• Flow sensor data indicates proper system functioning, filter fouling and are used for post-processing and QC
• Removable flow sensor windows for flow visualization, cleaning and servicing
• Software allows for valve scheduling, manual setting of valve position and logs flow rates and system state to hourly ASCII files
• Rugged construction for use in laboratory, ship-board, or dock-side applications
