Introduction
MQV high performance, digital mass flow controllers with advanced
functions have been developed for the general industrial application.
They feature flow rate control with high speed and wide range ability.
MQV
controllers integrate three component technologies: the ultra
quick response μF (Micro Flow) thermal flow sensor, made with pro-
prietary Azbil Corporation technology, a proportional solenoid valve,
and advanced actuator control technology.
Integrating these technologies has achieved a high-speed control with
low differential pressure.

Features
• High-speed controllability
Fast response of 300 ms or less*
(500 ms for the MQV9020/9050 .)
* Response time is the time required for the controlled flow rate to
reach ±2 % of the set value, starting from the fully closed state or
from when the set value is changed during control.
• Low differential pressure operation
MQV controllers can operate at a low differential pressure of 50 kPa
or less.
•
Wide control range
Wide control range of 1 to 100 % FS
•
Wide product line-up
There are two types of models, those with integrated display and
those with separate display. On models with separate display, the
display unit can be detached to allow remote operation via the dedi-
cated 2 m cable.
