D07-9 Thermal Analog Gas Mass Flow Controller

The D07-9 thermal mass flow controller/flow meter utilizes the capillary heat transfer differential thermometry principle. It features a settable analog range and is not susceptible to fluctuations in temperature and pressure, eliminating the need for temperature and pressure compensation while enabling precise measurement and control of various gases. The D07-9 series is a high-precision, fast-response analog product developed by Hua Cheng Electronics.

Advantages

Stable Control, Good Repeatability

Accuracy is less than ±1.5%F.S., linearity is less than ±1%F.S., and repeatability is less than ±0.2%F.S.

Stable at Zero, Insensitive to Position

Adopts a brand-new analog sensor, with horizontal calibration and support for installation in any direction.

Easy to Maintain

Designed to be simple, easy to use, and easy to maintain, reducing both usage and maintenance costs.

Innovation

Valve Control Technology of VCP

Valve control technology adopts a number of new achievements, collectively known as VCP technology. This structure has a small internal gas dead zone, fast valve response speed, and no hysteresis. Using VCP technology can effectively improve the flow control stability of the gas mass flow controller.

Constant Power Sensor
