Azbil MQV Digital Mass Flow Controller Standard Gas, Medium Flow Rate Models features high-performance mass flow controllers that incorporate a thermal mass flow sensor developed by Azbil Corporation, the µF (Micro Flow) sensors, in addition to a proportional solenoid valve and advanced actuator control technology. 700 ms control can be used for low differential pressure work. The ultra-high-speed response Micro Flow sensor and unique PID tuning realize exceptionally high-speed response in reaching the set flow rate from a fully closed state. Material of gas-contacting parts 316 stainless steel, Teflon, fluororubber. Selectable control range, power circuit isolation, and emphasis on usability. The MQV series does not use capillaries that have large pressure loss, so the MGV series can control in the low pressure difference. The MQV Series comes with a multitude of standard functions such as flow rate, indication and totalizing. A convenient personal computer loader function has been integrated as a standard feature. The MLP loader software, which is sold separately, allows not only configuration of various settings, but also monitoring of flow rate trends and other operating status information on the PC screen. Acquired data can also be saved on a CSV file. The power circuit is isolated from analog I/O circuits. If multiple MQV controllers are connected to analog I/O by a PLC or the like, there is no need to use an isolated circuit in the analog module on the PLC side. A common power supply can be used to supply power to the MQV. MQV controller can operate at a allow differential pressure of 50 kPa or less. An AC adaptor is available that is suitable for use in laboratory setting or for similar application. On models with a integrated display, the display direction can be changed 180 degrees.
