Flow Controller MFC900 High Sensitivity, Minimal Initial Flow
Response Speed, Fast Full Range Measurement, High Stability, High
Accuracy, And Excellent Repeatability
The MFC900 series, a digital gas quality controller, is made using
microelectromechanical systems (MEMS) flow sensing chips and is
suitable for measuring clean, relatively dry small flow gases and
process control for various purposes. Its unique packaging
technology enables the product to meet different ranges of flow
measurement, ensuring high sensitivity, reliability, stability, and
low cost. The MFC900 series is composed of MEMS flow sensing units
and high-precision digital processing and calibration circuits
(MCU) The integrated Δ - ∑ A/D converter, logic circuit with
internal calibration function, MCU processor, and display unit
module jointly ensure the real-time and effective acquisition of
sensing signals, obtain accurate flow signals, and perform
corresponding compensation algorithm processing internally. The
testing principle of the flowmeter determines that no external
calibration compensation is needed to ensure high-precision flow
output; A friendly digital output communication method, users can
easily use digital communication to obtain corresponding rich data
information; The product has a wide range of applications.
