DMF-41431

DMF-41431 is a DMF series digital mass flow controller. It program, record, analyze, and control flow rates of various gases with digital mass flow controller. Controller is designed with straight tube sensors with restrictor flow elements to ensure laminar gas flow for accurate and repeatable results. It is unaffected by temperature and pressure variations. Controller can be programmed for various control functions including flow set point, totalizer, stop totalizer, totalize from preset flow, stop and preset total, auto zero, and more. Auto zero feature utilizes an automatic balancing circuit that virtually eliminates drift of zero and span. In addition, controller has two dry contact closures to operate pumps, valves, or other process equipment. It features an auto tune function to optimize control response for a specific gas under actual process conditions. Self diagnostic tests are run at power up to ensure the controller is in optimum working condition.
