Pro-Meter® VDK Dispensing Systems Compact gear meter technology delivers precise, consistent material application. The Nordson® Pro-Meter VDK dispensing module combines gear metering technology with compact size to provide unmatched precision and control in dispensing high-viscosity silicones, butyls, epoxies and hot melt materials. The module is designed for use in form-in-place gasketing, bonding and sealing operations. The wrist-mountable design positions the Pro-Meter module close to the point of application, minimizing the effects of pressure and viscosity changes. With the Pro-Meter VDK module, you achieve precision bead profiles, accurate shot weights and consistent gasket sizes, realizing potential material savings. Precise Metering Positive-displacement, spur gear pumps are linked to an encoder feedback servo drive within the Pro-Meter VDK module. This closed-loop control provides precise volumetric output. Spur gear design eliminates side loads that can lead to premature wear. External speed input reference signals allow synchronization with automation speed providing uniform material deposition. Nozzle Pressure Control Typical pressure-fed systems are subject to differences between their dynamic and static pressures, and are generally only accurate to ±10 percent. The Pro-Meter VDK gear metering system controls material delivery by positive displacement, limiting pressure differentials. This dispensing system is capable of ±1 percent. Placing the gear meter close to the point of material application minimizes variation in the nozzle pressure. Close proximity also provides faster response time when changing flow rates and output. Nozzle output pressure is controlled so is not affected by system pressure drops. Application Versatility The Pro-Meter VDK dispensing module can be retrofitted to existing systems to improve output control and may be installed with new systems to meet a wide range of application requirements. Standard Pro-Meter VDK models have output ranges from as low as 0-15 cc per minute with a small displacement pump and from 0-600 cc per minute using the largest displacement pump. Mounting configurations include direct module attachment with a Nordson Blue Series™, Auto-Flo™ or AG900 gun, or remote mount with a gun of choice. Diagnostics and Options The Pro-Meter VDK module monitors volumetric output, flow rate and system pressure; readings are displayed on two individual digital readouts. Separate alarm signals are generated if pressure or output volume exceed preset limits.
