iQ Electronic Flow Controller

Precise flow for the demanding applications

iQ Electronic Flow Controller is designed for applications that require high-precision flow control. It provides exceptional reliability and repeatability. It thrives in settings that require precise control and quick response times. It is designed to maintain a steady flow rate and is perfect for precision flow control in a variety of applications. 

Reliable and Consistent Operation 

The iQ Electronic Flow Controller uses a thermal sensor for accuracy and quick response, resulting in good linearity and repeatability. It functions well within an operational pressure range of 20-100 psig, ensuring precision with <1% full-scale linearity and <2% full-scale accuracy. 

Efficient and Durable Performance 

The Electronic Flow Controller, with a resolution of <25mV and a turndown ratio of 100:1, offers exceptional flexibility and precise control, allowing it to handle significantly lower flow rates. This feature, combined with its ability to withstand operating temperatures from 32°F to 120°F, ensures durability and reliable performance across various applications. Its robust design supports a variety of gases*, making it well-suited for demanding environments where long-lasting performance is critical. 

Versatile and Easy to Install 

The Electronic Flow Controller accepts 0-5V, 0-10V, and 0-20mA control signals. It has an 8-pin electrical connector for easy installation and a low power requirement of <300mA. It is equipped with overcurrent and reverse polarity protection, along with a built-in power indicator.
