Program, record, analyze, and
control flow rates of various gases with Series DMF Digital
Mass Flow Controller. Controllers are designed with straight
tube sensors with restrictor flow elements to ensure laminar
gas flow for accurate and repeatable results. Series DMF are
unaffected by temperature and pressure variations.
Controllers 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,
Series DMF controllers have two dry contact closures to operate
pumps, valves, or other process equipment.
The Series DMF 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. Calibration
information for up to 10 gases and conversion factors for up
to 256 different gases are stored in memory. High and low gas
flow alarm limits are programmed via RS-485 interface. Software
supports programmable flow modes, allowing execution of custom
programming of up to ten steps. Dimensional Information |
