Fluid Metering, introduces the New V300 Stroke Rate Controller for precision control of all FMI V-Series Variable Speed Metering Pumps. The V300 is designed for accurate fluid metering in laboratory, R&D, test stands, pilot plants, process, and production applications. Front panel membrane switches offer convenient manual setting of pump stroke rates adjustable in 0.1% increments. Stroke rate can also be controlled electronically through an interface which can accept 4-20mA, 0-5 VDC, and 0-10 VDC input signals typically provided by process sensors and instrumentation. A 3 1/2 digit LCD readout displays either the percentage of flow rate in the manual position or the actual percentage of selected input signal when controlled electronically. The V-300 is capable of variable control of fluid flow from 0 up to 4 L/min in both forward and reverse directions. In addition, membrane switches can start and stop the pump without the need for re-adjustment of stroke rate settings. The V300 operates on 100-240V 50/60 Hz and is CSA, CSA-US, and CE rated. The unit is compatible with the RHV, QV, QVG, and Q2V Ratio:Matic pump models providing flow ranges from 0 to 4 L/min (60 gal/hr) at pressures up to 100 psig (6.9 bar). When used with the Q2V Ratio:Matic Dual Pump Drive, exceptional proportional metering of two fluids, up to 500:1 ratio, can be accomplished.
