VERFAHREN ZUR BESTIMMUNG EINER VENTILÖFFNUNG FÜR EINEN MASSENFLUSSREGLER |
摘要 |
<p>A system and method for controlling a mass flow controller to have a constant control loop gain under a variety of different types of fluids and operating conditions, and for configuring the mass flow controller for operation with a fluid and/or operating conditions different from that used during a production of the mass flow controller. Further, the system and method includes providing control by reducing the effects of hysteresis in solenoid actuated devices by providing a non-operational signal to the solenoid actuated device.</p> |
